Quick answer: what to know before you move

What distinguishes this assignment. A 579-acre base on the Miura Peninsula on Tokyo Bay, about 30 miles southwest of Tokyo, home of the U.S. Navy Seventh Fleet and host to 13 afloat commands plus more than 50 shore and tenant commands. An OCONUS tour in a dense, non-English-speaking metropolitan region with an exceptional rail network and housing priced for Tokyo commuters.

Biggest housing decision. Not "on-base or off-base" as a free choice. For accompanied members, residing in Military Family Housing is required when MFH is available; only if MFH is not available within 60 days of arrival may the member be authorized to live off base. Off base is the fallback, not the default.

Biggest cost pressure. Japan uses Overseas Housing Allowance plus Cost of Living Allowance — not BAH. OHA is a three-part package (rent ceiling, utilities and recurring maintenance, MIHA), and third-party 2026 figures for Japan disagree. Pull your own locality numbers from DTMO rather than planning around a blog's table.

Major commute consideration. Commuting here is multimodal: you walk from a gate to a ship and ride a train from a neighborhood station. Stations cited for base access include Yokosuka-Chuo, Shioiri, Kinugasa, Oppama, Uraga and Hemi. The gate-to-ship walk is a real share of door-to-work time and the part families most often forget to model.

School and health-care consideration. Schooling runs through the DoDEA/DoWEA federally operated system: Nile C. Kinnick High School on base, Ikego Elementary serving the Ikego housing area. Health care is TRICARE Overseas Program territory with an on-base Branch Health Clinic; specialty-care continuity, not the emergency room, is what to verify earliest.

Most important thing to verify before signing a lease. Written confirmation from the CFAY Housing Office of your off-base authorization status — without it the 60-day MFH rule governs your household.

Life at the installation

CFAY sits where Tokyo Bay meets the Pacific approaches, about 30 miles southwest of central Tokyo, across 579 acres. Its mission identity is unmistakable: home of the U.S. Navy Seventh Fleet, hosting 13 afloat commands alongside more than 50 shore and tenant commands. This is not a base where the installation is the whole town — Yokosuka City wraps it in a Japanese urban and coastal fabric of shopping streets, station districts, hospitals and beaches within a short train ride.

The physical address is 1 Banchi Tomarimachi, Yokosuka City, Kanagawa 238-0001, with mail to PSC 473 Box 1, FPO AP 96349. The base operator is 046-816-1110, DSN 113 — put it in your phone before you land.

Three realities shape daily life. The rail network is the transportation backbone, with central Tokyo about an hour away and Kinnick High School describing itself as roughly 45 km from Tokyo. Neighborhood-level walkability is real around station-front commerce. And the language environment outside the gate is Japanese, which affects everything from medical appointments to school paperwork.

The installation carries a housing program spanning three housing geographies, a school, a clinic with pharmacy and laboratory services, a dental clinic, mental health services and MWR programs. Book MWR activity through Navy MWR Yokosuka, not a third-party summary.

Weather is a daily-life factor, not a backdrop. The recorded climate profile is humid subtropical — summer averaging about 86 °F, winter about 42 °F, roughly 63 inches of precipitation a year — with typhoons, earthquakes and tsunamis as the named hazards. Expect real summer humidity, a genuinely wet rainy season, and a household typhoon and earthquake plan, because both the base and Japanese authorities expect one.

Best places to live nearby

One caveat governs this section: because MFH is mandatory when available, off-base neighborhoods matter mainly to households already authorized to live off base, and secondarily to families comparing areas they may later be offered. Rent evidence is labeled by kind; none of it is a Yokosuka median.

Maborikaigan (eastern Yokosuka City, chome 1–4). IINO Real Estate's area guide calls it "the most popular area for military families" — agency-published marketing, not an independent measurement — with an agency-stated 13-minute drive from the main gate, about 2,000 families, development since the 1970s, and two-parking-space properties common. Suits households wanting a short car commute and room for two vehicles, in larger detached and low-rise homes with unusual parking provision. Rent evidence: none captured. Commute basis: the agency's stated 13-minute drive. Shopping/services: eastern Yokosuka City services. Health care: city facilities plus the on-base clinic. Recreation: Tokyo Bay frontage. Advantage: the shortest, most car-friendly base access named here. Tradeoff: the popularity claim is the agency's own, and parking premiums are priced in.

Yokosuka-Chuo. RealEstateGuide.jp's off-base guide highlights central convenience — base access, shopping, restaurants, errands — and shorter commutes. Suits households wanting station and errands on foot rather than a car-first pattern; urban apartments over commercial streets. Rent evidence: none captured — treat any figure as an advertised asking rent until verified as a market statistic. Commute basis: named as a base-commute station. Schools: the DoDEA/DoWEA set serving the installation. Shopping/services: strongest day-to-day commerce of the named areas. Health care: city facilities plus the clinic. Recreation: station-district dining and easy regional rail. Advantage: minimal car dependence. Tradeoff: density and less parking than the eastern city areas.

Shioiri. The same guide names it convenient for base access, shopping, restaurants and errands, and favorable for shorter commutes. Suits a compact daily radius in urban apartments. Rent evidence: none captured. Commute basis: a named commute station. Shopping/services: strong local commerce. Health care: city facilities plus the clinic. Advantage: convenience density. Tradeoff: the space, parking and quiet you give up in any station district.

Keikyu corridor stations (Kinugasa, Oppama, Uraga, Hemi). These appear in the research as stations cited for the base commute — reference points, not characterized neighborhoods. Suits a rail-based peninsula commute. Housing type, rents, schools, services, health care and recreation were not captured; verify locally. Advantage: rail access outside the central station districts. Tradeoff: the research establishes neither character nor price level, so treat these as leads to investigate, not recommendations.

Zushi. Zushi Portal's Zushi/Hayama comparison, citing municipal data and Japanese listing platforms, describes a coastal resort municipality west of Yokosuka with a walkable station-front, a quieter west side around Sakurayama, and an east-exit area efficient for commuters. Suits households trading a slightly longer rail commute for coastal living and calmer streets, in mixed station-front apartments and hillside residential. Rent evidence: none captured. Commute basis: Keikyu and JR rail, with the east-exit area the commuter-efficient one. Schools: the DoDEA/DoWEA set — Ikego Elementary serves the Ikego housing area in Zushi, but neighborhood-to-school assignment is not guaranteed. Shopping/services: coastal municipal services, bus and rail links. Health care: city facilities plus the clinic. Recreation: beaches, coastal walks, resort-town food, plus resident impressions. Advantage: genuinely walkable daily life with sea access. Tradeoff: station-front premiums and a longer run to the main gate.

Hayama. The same comparison describes Hayama as quiet, with protected sea-and-mountain scenery, and explicitly notes lower daily convenience than Zushi. Suits households for whom scenery, quiet and outdoor access outweigh errands, in low-density residential across a protected landscape. Rent evidence: none captured. Commute basis: not established in this pass — verify before committing. Shopping/services: limited relative to Zushi by the comparison's own account. Recreation: the strongest sea-and-mountain outdoor profile of the named areas. Advantage: space, quiet, landscape. Tradeoff: daily convenience.

Preference-based guidance

Shortest commute: Maborikaigan on the agency-stated 13-minute drive basis, or a station district with direct rail — but the gate-to-ship walk is part of door-to-work time however you arrive. Housing value: nothing here supports a value ranking. Advertised asking rents sampled from offbase.jp current listings run from ¥189,000 for 864 sq ft and ¥240,000 for 1,380 sq ft up to ¥500,000 for 1,517 sq ft at Spanish Hills and ¥470,000 for 1,700 sq ft — all asking rents from a sample, not a median. Schools: the determinant is the DoDEA/DoWEA system and your eligibility, not a neighborhood's reputation; never rent on an assumed assignment. Walkability: Yokosuka-Chuo, Shioiri and Zushi station-front are the areas the cited sources actually call walkable. Outdoor: Zushi and Hayama, with Hayama stronger on scenery and weaker on convenience. Urban: the Chuo and Shioiri districts. Medical: favor proximity to city facilities for continuing specialty needs and confirm TRICARE Overseas Program participation before signing. Space and parking: Maborikaigan is the one area the evidence describes as commonly offering two-parking-space properties.

On-base vs off-base housing

The decisive installation-specific fact: for accompanied members, residence in Military Family Housing is mandatory where MFH is available, and only if MFH is not available within 60 days of arrival may the member be authorized to reside off base. That rule appears in the CFAY housing FAQ published for incoming personnel, and determinations are made by the Housing Office — so this guide states the rule rather than predicting anyone's outcome.

Government housing areas. Three have been in the picture: Yokosuka on the main base, Ikego in Zushi, and Negishi in Yokohama. Negishi was returned to Japan for redevelopment, reported by Stars and Stripes on 2026-07-01. Treat realistic inventory as Yokosuka and Ikego, and the Negishi change as a completed event rather than pending policy.

Eligibility and application. Eligibility flows from accompanied status and your orders, applied through the CFAY Housing Office; Military.com's CFAY housing guide is useful secondary orientation. Do not rely on a broker, forum post or third-party summary for authorization status.

Availability verification. No current CFAY on-base wait-time figure is published in the sources reviewed here, and none is asserted. The 60-day window is a rule with a clock attached; ask the Housing Office to document, in writing and early, where you sit relative to it.

Utilities. On-base and off-base arrangements differ, and the local grid runs 100V / 50 Hz. Verify appliance by appliance — a 120V/60 Hz device will not behave the same, and transformers are not a universal fix.

Pets. No primary-source pet policy for CFAY MFH was captured, and Japan import involves Japanese authorities as well as the installation. Make no pet decision on any claim, including anything here, without written confirmation from the Housing Office and the relevant quarantine authority.

Schools, space and commute. Kinnick High School is on the base and Ikego Elementary serves the Ikego housing area, so living on base shortens school logistics. On-base housing in Japan is generally more compact than stateside expectations; the offset is that it removes the train-and-gate walk from your day.

Temporary lodging and rent vs. buy. Confirm temporary lodging directly with the installation — no rate, availability or eligibility claim is made here. OHA is an allowance for renting, and nothing in this evidence supports a purchase path for a typical accompanied tour.

Cost of living

Start with the misconception that costs families the most planning time: Japan does not use BAH. Yokosuka uses Overseas Housing Allowance plus Cost of Living Allowance, and a budget built on a stateside BAH assumption will be wrong in both size and mechanics.

The OHA framework, in three parts. OHA comprises the rent ceiling, the utilities and recurring maintenance allowance, and the Move-In Housing Allowance (MIHA) for move-in costs. Yokosuka's OHA locality is JA043. Because third-party 2026 sources conflict — MilitaryToolkit's Japan OHA page reports a monthly utility allowance equivalent to about ¥112,012 (roughly $732.82 at publication) while another source reports $450, and a separate source attributes a $1,900 E-5–E-6 rent ceiling and $370 MIHA to Yokosuka — this guide states no dollar ceiling and no utility figure. Pull your own locality's figures from the Defense Travel Management Office's Overseas Housing Allowance page, using the MilitaryToolkit OHA calculator only as a sanity check at most.

COLA. Yokosuka's index is reported at 110 — roughly 10 percent above the U.S. baseline, against 108 at Yokota and 102 on Okinawa — per aggregator calculators with an index date of 2025-12-31. COLA is non-taxable and subject to change: do not build rent on a COLA assumption, and do not treat an aggregator index as permanent. Those tables live at the MilitaryToolkit OHA rates index; DTMO remains authoritative.

Recurring costs to model: rent against the ceiling, utilities and recurring maintenance, internet, renters insurance, groceries, transport, rail fares and any road tolls, child care, taxes. One-time costs: MIHA-eligible move-in costs, the outlays of setting up a household on 100V / 50 Hz power, and OCONUS shipping and storage frictions.

Currency sensitivity. OHA, COLA, rents and everyday costs here are yen-denominated, so every USD figure in any guide — including this one — shifts with the exchange rate. Plan in yen.

A note on comparisons. The batch specification calls for BAH illustrations using a stateside example. BAH does not apply at CFAY, so rather than transplant a stateside figure into a Japan article, this guide states the OHA/COLA framework and points to DTMO.

Schools

Schooling runs through the federally operated school system, branded on current official pages as the Department of War Education Activity (DoWEA) and long known as DoDEA — a naming transition in progress, with both labels in circulation. It is described as one of 161 accredited schools and serves children of active duty military members and DoD civilians.

Nile C. Kinnick High School, "Home of the Red Devils," sits on Yokosuka Naval Base about 45 km from Tokyo, roughly an hour by train, and publishes enrollment as usually around 600 students — approximate. It opened in Yokohama in 1946, moved to Yokosuka in 1971 into a renovated Marine Barracks building, and was named for Nile C. Kinnick in 1990; Kinnick was a Heisman Trophy winner from the University of Iowa killed in a WWII training flight off USS Lexington. Published awards include AP Honor Roll Platinum in 2025 and 2024, Gold in 2023, and a Cognia System of Distinction in 2022.

Ikego Elementary School serves the Ikego Housing Area in Zushi with grades PK–5, publishes enrollment at about 400 students — again approximate — and holds a Cognia System of Distinction from 2022. Kinnick and Ikego are the two schools surfaced directly by these sources; other schools in the Pacific East structure may serve your household depending on address and orders.

What to verify: boundary and eligibility determination for your specific address and status; enrollment steps and records; the school liaison officer's role in your transition; mid-year transfer timing; special education and IEP/504 processes; and transportation eligibility. DoWEA immunization requirements for school year 26-27 are published. Do not accept a neighborhood-to-school assignment as guaranteed, and do not reduce a school's quality to a commercial rating — read the school's own published information and talk to the liaison.

Child care

On an installation of this size, care typically spans Child Development Centers, Family Child Care and School Age Care, with registration managed through the installation's Child and Youth Programs. This pass captured no CFAY-specific availability, wait-list length or fee schedule, and none is invented here.

Process: register as early as orders allow, ask explicitly for current wait-list position and estimated movement, and ask which priority category your household falls into. Military OneSource publishes the services framework and eligibility context, and Military.com publishes the fee structure framework. Use those for structure; get CFAY's actual numbers from CFAY. Civilian alternatives exist in Yokosuka and Zushi, but no verified provider-level information was captured — verify licensing, language of care and hours directly before enrolling.

Health care

Facility and services offered. On-base care is at Branch Health Clinic level, recorded as Level 2, a Community Hospital / Multi-Specialty Clinic, with primary care, pharmacy, laboratory, radiology, urgent care, periodic health assessments, immunizations and physical therapy. Dental clinic, mental health services and preventive medicine are also on the installation. Yokosuka falls under the TRICARE Overseas Program (TOP) — a different structure from stateside TRICARE regions. Verify TOP participation and referrals for any specific provider.

On-base care. Yokosuka hosts U.S. Naval Hospital Yokosuka, which Navy Medicine describes as the largest U.S. military treatment facility on mainland Japan: a 47-bed core hospital in Yokosuka, near Tokyo. It is part of Navy Medicine Readiness and Training Command (NMRTC) Yokosuka.

Where mainland Japan is served from. The same command lists branch health clinics in Sasebo, Iwakuni, Atsugi, Camp Fuji, and Yokohama in mainland Japan, plus Chinhae in Korea and Diego Garcia in the Indian Ocean. If you are assigned to one of those sites, expect primary care locally and specialty care routed to Yokosuka — Branch Health Clinic Atsugi, for example, states plainly that specialists are at USNH Yokosuka, roughly one to two hours away by a weekday shuttle.

Do not confuse mainland Japan with Okinawa. Okinawa is a separate island chain roughly 1,500 km southwest, served by U.S. Naval Hospital Okinawa at Camp Lester. A mainland-Japan assignment does not put you near it, and any source that names an Okinawa facility as the nearest hospital to Yokosuka, Misawa, Atsugi, Sasebo, Camp Fuji, or Kure is wrong about the geography.

Separate five questions for any facility you count on: (1) how close is it; (2) what services does it actually offer; (3) is your dependent eligible there; (4) does it participate in the relevant TRICARE network or referral path; (5) is it accepting new patients. Proximity says nothing about the other four.

Continuing specialty care — verify before you move: that a named provider is available and accepting patients; the referral path from the on-base clinic; whether care is delivered on base or in a Japanese facility; prescription continuity for maintenance medications; and the pediatric and behavioral-health pathways. Emergency and maternity planning belong in the same conversation — confirm which facility you would actually be routed to. EFMP families should complete screening and open the conversation with the gaining installation as early as possible; the on-base service list is not a substitute for confirming your specific specialty need.

Spouse employment and education

Japan adds real constraints: a Status of Forces Agreement environment affects what employment is available to dependents and where, so OCONUS rules — not stateside assumptions — govern your spouse's search. Research that first, using the installation as your source for how the rules apply to you.

Paths worth pursuing: federal and installation employment, including the NAF and MWR structure and the tenant-command ecosystem that comes with 50+ shore and tenant commands; spouse employment programs; and remote work for U.S.-based employers, which sidesteps many local labor-market constraints but raises tax and time-zone questions — Yokosuka runs 13–14 hours ahead of U.S. Eastern time depending on daylight saving.

Yokosuka City and Zushi have local employment markets, but language is a real gate, and no verified employer-level capture for dependents exists in this evidence. For education, colleges and credentialing pathways exist regionally and through military-affiliated programs; verify accreditation and transferability with the program and your state licensing body before relying on a credential.

Things to do

Routine local life: coastal walking and cycling along Tokyo Bay; station districts for dining and shopping; MWR programs booked through Navy MWR Yokosuka, the installation's own channel and the only source to use for what is currently running; and base community and youth programming. No prices, hours or discounts are stated because none were verified.

Destination trips: Tokyo is roughly an hour by train and about 45 km away, which makes day trips routine rather than once-a-tour events. The Miura Peninsula offers coastal and outdoor days, Zushi and Hayama add a resort-town and beach dimension on the western side, and Kamakura and the wider Kanagawa region sit within the same rail network.

By age band. Young children: coastal parks, local play facilities and MWR-booked base programs. Teens: the rail network is the real asset — independent travel to Tokyo and Yokohama defines this assignment for teenagers. Outdoor households should build the year around the coast and peninsula. Seasonal: summer heat pushes activity into water, early mornings and air-conditioned venues; the rainy season is a real stretch; typhoon season demands a plan; autumn and spring are the travel windows.

Weather and local challenges

The recorded profile — humid subtropical, summer averaging about 86 °F, winter about 42 °F, roughly 63 inches of precipitation a year — means a wet, humid environment rather than a temperate one, with typhoons, earthquakes and tsunamis as the named hazards.

Practical implications: build a typhoon kit and know your shelter plan; anchor tall furniture and know what to do when the ground moves; treat the rainy season as a logistics constraint on moves and travel; and expect humidity to affect storage, electronics and household goods. Weather closes roads and disrupts rail — build buffer into appointment days.

The less-discussed challenge is isolation. Yokosuka is not remote, but it is linguistically isolating for a spouse who does not speak Japanese, and the first months require deliberate effort to build a network. Base community programs and the school community are the two most reliable bridges.

Safety

This pass captured no official crime statistics for Yokosuka with a defined geography and reporting period, so no crime figures or area safety characterizations appear here. Obtain published statistics from the relevant Japanese prefectural and municipal police sources and from installation-provided safety and emergency information rather than relying on neighborhood reputation or forum impressions. Hazard preparedness — typhoon, earthquake, tsunami — is better documented in the sources reviewed here and is the more actionable planning item.

Pets

No primary-source pet policy for CFAY Military Family Housing, on-base veterinary services or dog park facilities was captured, and no verified detail on Japan's animal import requirements was captured either. No claim is made in those areas.

What can be said honestly: moving a pet to Japan involves Japanese government animal quarantine authorities in addition to U.S. military transportation, and the timelines typically require planning well before your pack-out. Start with the CFAY Housing Office for housing policy and the Japanese quarantine authority for the import path, then confirm transport through your transportation office. Do not rely on a guide, including this one, for those specifics.

PCS checklist

60–90 days before

  • Open the housing conversation with the CFAY Housing Office early enough to understand how the mandatory MFH rule and the 60-day window apply to you.
  • Pull your own OHA framework figures for locality JA043 — rent ceiling, utilities and recurring maintenance, MIHA — from DTMO, not a third-party table.
  • Treat COLA as a variable income line, not fixed income.
  • Start the pet path with animal quarantine authorities; contact DoWEA schools and the school liaison about enrollment, records and any IEP/504 needs.
  • Register with Child and Youth Programs for child care; begin the EFMP or specialty-care conversation if it applies.

30 days before

  • Get written documentation of your housing status and where you sit relative to the 60-day clock.
  • Confirm temporary lodging directly with the installation.
  • Build a yen-denominated budget separating recurring from one-time costs.
  • Note the base operator (046-816-1110, DSN 113) and verify the appliance plan for 100V / 50 Hz.

Before signing anything

  • Confirm off-base authorization in writing, and confirm rent against the applicable ceiling.
  • Verify TRICARE Overseas Program participation and the referral path for every provider you plan to use.
  • Verify school eligibility for the specific address — never assume by neighborhood.
  • Read the lease in translation, including move-out conditions.

Arrival week and first 30 days

  • In-process through the Housing Office before committing to any off-base arrangement.
  • Register with the medical clinic and establish primary care; get transit cards and learn your station-to-gate route.
  • Confirm child care placement status in writing and set up the household hazard plan for typhoon, earthquake and tsunami.
  • Build a social network deliberately — the base community and school are the fastest routes.

Common mistakes

Budgeting on BAH. Japan runs OHA plus COLA. A stateside BAH assumption starts the tour with a structural budget error.

Treating off-base housing as the default. For accompanied members MFH is mandatory when available; off base is the authorized fallback when MFH is not available within 60 days. Planning around an apartment before understanding this rule is the most expensive sequencing mistake.

Planning around a third-party OHA table. 2026 third-party Japan figures conflict by hundreds of dollars a month. Use DTMO for your locality.

Counting on Negishi. The Yokohama housing area was returned to Japan for redevelopment, reported 2026-07-01. Any guide still listing it as inventory is out of date.

Modeling the commute as a drive. The gate-to-ship walk and the train ride dominate many Yokosuka commutes. Model door-to-work, not gate-to-gate.

Assuming a school by neighborhood. Assignment is not guaranteed by address; verify eligibility and placement directly.

Assuming proximity equals access in health care. Distance tells you nothing about services, dependent eligibility, network participation or new-patient status.

Forgetting the climate's operating costs. Roughly 63 inches of rain, summer humidity averaging about 86 °F and named typhoon risk make dehumidification, storage and insurance real line items.

Bottom line

Yokosuka rewards families who sequence correctly and punishes those who assume it works like a stateside PCS. The mission profile is remarkable — Seventh Fleet's home, 13 afloat commands, 50+ tenant commands, Tokyo an hour away — and quality of life is high in the neighborhoods the cited sources describe. But three things differ, and each changes a decision.

Short commute. The mandatory-MFH rule may resolve the question for you. If MFH is available you live on base, and the planning question becomes how to make base housing work rather than how to find an apartment. If MFH is not available within 60 days, your off-base shortlist matters, and Maborikaigan's agency-stated 13-minute drive or a walkable central station district becomes the realistic comparison.

Budget. The OHA framework is your planning spine: rent against a ceiling, plus utilities and recurring maintenance, plus MIHA, with COLA layered on — pulled from DTMO, denominated in yen, treated as changeable. The conflicting third-party figures are a warning, not a data set.

Children and schools. The system is DoWEA-run and assignment depends on eligibility, not address reputation. Confirm early and lean on the school liaison.

Medical continuity. Verify the five questions — proximity, services, eligibility, network, new-patient status — before committing.

Urban life, walkability, outdoor living or space. The trade runs from central Yokosuka's station districts, to Zushi's walkable coastal station-front, to Hayama's quieter sea-and-mountain setting, to Maborikaigan's parking and space. None is universally best; each wins on a different axis.

The one decision that outranks all of them: get your housing authorization documented before you sign anything.

FAQ

Does Yokosuka use BAH? No. Japan uses Overseas Housing Allowance plus Cost of Living Allowance — the most common misconception families arrive with.

Can I just rent an apartment off base? Not as an automatic choice. For accompanied members, residing in Military Family Housing is mandatory when MFH is available. Only if MFH is not available within 60 days of arrival may the member be authorized to live off base.

What are the three components of OHA? The rent ceiling, the utilities and recurring maintenance allowance, and the Move-In Housing Allowance (MIHA) for move-in costs. Pull your own figures from DTMO.

What is Yokosuka's OHA locality code? JA043.

Where is the government housing? Yokosuka on the main base and Ikego in Zushi. Negishi in Yokohama was returned to Japan for redevelopment, reported 2026-07-01.

Which schools serve the base? Nile C. Kinnick High School on Yokosuka Naval Base, and Ikego Elementary School (PK–5) serving the Ikego Housing Area, within the federally operated DoDEA/DoWEA system.

How big is Kinnick High School? The school publishes enrollment as usually around 600 students — approximate.

What health care is on the installation? A Branch Health Clinic at Level 2, Community Hospital / Multi-Specialty Clinic, with primary care, pharmacy, lab, radiology, urgent care, PHA, immunizations and physical therapy, plus dental, mental health and preventive medicine. TRICARE runs through the TRICARE Overseas Program.

How far is Tokyo, and which stations do people commute from? The base is about 30 miles southwest of Tokyo, roughly 45 km and an hour by train. Stations cited for the base commute are Yokosuka-Chuo, Shioiri, Kinugasa, Oppama, Uraga and Hemi.

What is the electricity setup? 100V / 50 Hz. Verify appliance compatibility rather than assuming a transformer solves everything.

What should I verify before signing a lease? Your written off-base authorization from the CFAY Housing Office — first, before anything else. Everything downstream depends on it.
