Yokosuka
CFAY · Commander, Fleet Activities Yokosuka · 7th Fleet Home Port
The biggest US Navy hub in the Pacific. Home of 7th Fleet and the USS George Washington carrier strike group. Kamakura is thirty minutes away. Tokyo is an hour. The train system is one of the best in the world. Most sailors spend their liberty on Dobuita Street when they could be anywhere in Kanto. This guide is for the sailors who want to actually see Japan.
Commander, Fleet Activities Yokosuka (CFAY) is 7th Fleet's home port — the largest US Navy base in the Pacific, located on the Miura Peninsula in Kanagawa Prefecture, about 40 minutes by train from Yokohama and 60–80 minutes from central Tokyo. Yokosuka City is a mid-size Japanese port city built around the base, generally safe, with a long history of US military presence dating to the post-WWII occupation era. Liberty hours and restrictions are set by CFAY policy and layered by each command — check with your chain of command, not the internet.
Quick Facts
Getting Around
The train system is your primary tool. Japan Rail (JR) and private lines like the Keikyu connect Yokosuka to the entire Kanto region with punctuality that will ruin you for every other country's public transit. Learn it once and the whole region opens up.
Runs from Yokosuka station directly to Zushi, Kamakura, Ofuna, Yokohama, Tokyo, and through to Shinjuku (on the Shonan-Shinjuku Line, same track). This is your primary route for day trips. Yokosuka station is a short distance from CFAY. The line runs frequently and reliably. Use Google Maps Japan for real-time departure times including last trains.
A private line connecting to Yokohama (about 30 minutes) and continuing to Shinagawa, central Tokyo, and toward Haneda Airport. Yokosuka-Chuo station is the main Keikyu stop near the base. For Yokohama Chinatown and Minato Mirai, the Keikyu to Yokohama then transfer is the route. The Keikyu also connects to the Miura Peninsula (Misaki direction) for tuna port day trips.
Buy at any major station — machines have English menus. Small deposit required (verify current amount locally). Load yen, tap in, tap out — the system calculates the exact fare. Works on JR, Keikyu, Tokyo Metro, and most transit in the Kanto region. Also works at 7-Eleven, many vending machines, and increasingly at convenience stores. Not optional infrastructure for anyone spending more than one day in Japan.
Available, safe, reliable, and expensive. Metered. Useful for short distances at odd hours or when the train math doesn't work. If you're pricing a taxi back to base from Tokyo, check before you commit — it will be significantly more than you expect. Taxi apps may be available in the area — verify locally, as availability changes.
The Honcho shopping area and Dobuita Street are within walking distance of the main CFAY gate. This is the on-foot liberty zone. Beyond Yokosuka City, the train is the vehicle. Bikes are common in Japan and rental options exist in the area — verify locally.
Dobuita Street
Dobuita Street runs from the main CFAY gate through Yokosuka's entertainment district. It has been the primary liberty strip for US sailors since the post-WWII occupation era — "Thieves' Alley" in the old slang, though the name is more colorful than accurate today. The street is a mix of bars, tattoo shops, American-style restaurants, souvenir shops, and establishments that have catered to US military customers for generations.
Use it as your starting point, not your destination. It is convenient, English-friendly, and five minutes from the gate — which is exactly why it catches sailors who don't plan further. Kamakura and Tokyo are a train ride away from the same neighborhood. The sailors who look back on their Yokosuka tour as formative are the ones who used Dobuita for what it is — a warmup — and then got on the train.
The liberty incidents that restrict everyone's liberty — drunk and disorderly, altercations, poor judgment calls — disproportionately happen close to the gate on Dobuita and in the surrounding bars. Not because it's a bad place; because it's where the most sailors concentrate, the closest to base, late at night, after the most drinking. Be aware of the pattern.
Day Trips Worth Taking
Yokosuka's location on the Miura Peninsula puts you within train range of some of the best day trips in Japan. The sailors who leave Yokosuka saying "I barely left the base" are the ones who didn't look at the train map.

What Sailors Actually Need to Know
Dobuita (sometimes called "Thieves' Alley" by old-timers) is the commercial strip running from the main CFAY gate through Yokosuka City's entertainment district. It has been the liberty hub for US sailors since the post-WWII occupation era and it shows — bars, tattoo shops, American-style food joints, souvenir stands, and shops that have catered to US military customers for generations. It is convenient, it is the path of least resistance on liberty, and it is also the place where incidents happen. That's not a condemnation — it's a calibration. If you want to actually see Japan, Dobuita is where you start, not where you end up. It's a five-minute walk from the gate; Tokyo and Kamakura are a train ride away from the same neighborhood. Use both.
Yokosuka is credited with introducing curry to Japan. The Imperial Japanese Navy adopted a British Navy curry recipe in the late 19th century as a way to combat beriberi among sailors at sea. The recipe spread from the navy's base at Yokosuka into the general Japanese food culture, and Japanese curry — thick, mild, served over rice — became one of the most popular foods in the country. Yokosuka Navy Curry (Kaigun Curry) is a regional specialty sold throughout the city in different variations. It's worth eating not just because it's good but because it's a genuine piece of US-Japan naval history on your plate.
Japan's train system is remarkable in reliability, punctuality, and coverage. It is also finite: it stops running roughly midnight to 1 a.m. and resumes around 5 a.m. Missing the last train from Tokyo or Yokohama back toward Yokosuka means a taxi (expensive — verify current rates locally before you need one) or staying until the first morning departure. Know the last departure time for your return train before you go out. Set an alarm on your phone. Google Maps Japan gives accurate real-time train departure times including last trains. This is not a minor logistics detail — it has shaped the decision-making of more sailors than will admit it.
Buy a Suica or Pasmo IC card at any major train station. The machines have English menus. Load yen onto it, tap in when you board, tap out when you exit — the correct fare is deducted automatically. No figuring out fares, no fumbling with coins. The card works on essentially every train, subway, and most buses throughout the Kanto region (Yokosuka, Yokohama, Tokyo, Kamakura, etc.). A small deposit is required (verify current amount locally). Increasingly accepted at convenience stores and vending machines. If you're going to Yokosuka for any length of time, the IC card is not optional infrastructure.
US military personnel in Japan operate under the US-Japan Status of Forces Agreement, which defines legal jurisdiction and the treatment of US personnel under Japanese law. SOFA status is not immunity — it is a framework for cooperation between US and Japanese authorities. For certain categories of off-base offenses, Japanese authorities retain jurisdiction. Japan's legal system operates very differently from the US system, and pre-trial detention in Japan can be extended. The political sensitivity of US military incidents in Japan means that the US-Japan alliance itself has at times been affected by individual conduct. Being aware of this dynamic is not paranoia; it is understanding the operational environment you are operating in.
CFAY MWR (Morale, Welfare, and Recreation) runs tours, activities, and discounted tickets for attractions throughout the Kanto region — Tokyo attractions, day trips, cultural events, and more. MWR tours typically handle transportation and logistics, which removes the navigation barrier for sailors new to Japan. Discounted tickets for major attractions are another MWR resource worth checking. Visit the CFAY MWR office or check mwr.navy.mil/yokosuka for current offerings. Programs change seasonally. For sailors new to Japan, an MWR-organized tour for the first trip or two is a practical bridge to independent travel.
Liberty Policy — What Your Command Owns
Liberty hours, buddy system requirements, off-limits areas, and curfews are set by CFAY policy and then layered by each individual command. They change. They can tighten after incidents involving other commands and other ships. The information on this page is general orientation. Your Chief or duty officer is the only source for what applies to you, right now, before this liberty call.
Whether and under what conditions a buddy system is required is a command-level decision. When in effect, it is enforced. Getting caught solo when a buddy requirement is in effect is a disciplinary matter. Verify before you go out.
NCIS and the command designate specific areas as off-limits. These are not published on the internet and they change based on incidents, intelligence, and command judgment. Get a current brief from your chain of command.
Commands in Japan commonly conduct liberty briefings covering Japan-specific culture, SOFA implications, local legal risks, and behavior expectations. These briefings exist for reasons — they're a compressed version of hard lessons learned. Pay attention to them.
Under the US-Japan SOFA, US authorities have primary jurisdiction over off-duty offenses committed off-base in certain circumstances — but Japanese authorities retain jurisdiction in others. Japan's legal system operates very differently from the US system, and pre-trial detention can be extended. The JAG office at CFAY is the authoritative source for current jurisdictional guidance.
Questions Sailors Actually Ask
Do I need to speak Japanese to get around Yokosuka?
No — but it helps more than you'd expect. In Yokosuka City and on Dobuita Street near the base, many businesses have dealt with US sailors long enough to manage basic English transactions. In Tokyo, major tourist areas (Shibuya, Shinjuku, Asakusa, Harajuku) have significant English signage and English-capable staff. Kamakura and other day-trip destinations are well set up for foreign visitors. The further you get from tourist infrastructure, the less English you'll encounter. Google Translate with camera mode — point it at a menu or sign and it translates in real-time — is genuinely essential. Learning to read Katakana (one of Japan's phonetic scripts, used for foreign-origin words and many restaurant menus) takes a week and will meaningfully improve your ability to navigate. A few Japanese phrases — sumimasen (excuse me), arigatou gozaimasu (thank you), ikura desu ka (how much is this) — go a long way in daily interactions and are appreciated.
How do I get to Tokyo from the base?
Two train lines connect Yokosuka to Tokyo. The JR Yokosuka Line runs from Yokosuka station (a short distance from CFAY) directly to Tokyo and on to Shinjuku, with a travel time of roughly 60–80 minutes to central Tokyo depending on your destination. The Keikyu Line from Yokosuka-Chuo station connects to Yokohama (about 30 minutes) and continues to Shinagawa and central Tokyo, with a route toward Haneda Airport as well. Get an IC card (Suica or Pasmo) — you buy it at any major station with a small deposit, load yen onto it, and tap in/tap out at every gate. It works on trains, subways, and buses throughout Japan, and increasingly at convenience stores and vending machines. It eliminates the need to figure out the correct fare before every trip. Your US bank card will likely work at 7-Eleven ATMs for cash if you need to reload. Note: Japanese trains stop running roughly midnight to 1 a.m. — if you miss the last train back, you are looking at an expensive taxi or waiting for the first morning departure.
Is Yokosuka City safe for US sailors?
Japan is one of the safest countries in the world by essentially any measure, and Yokosuka is no exception. Violent crime against US military personnel from random strangers is extremely rare. The risks that actually materialize are the same everywhere: drinking too much, getting into a fight, wandering somewhere you shouldn't late at night alone, or making a decision you'd normally know better than to make. Japan's drunk and disorderly laws are enforced, and incidents involving US military personnel in Japan attract command attention at a level that doesn't happen stateside. An incident doesn't just affect you — it affects your shipmates' liberty, potentially for months. The cultural expectation in Japan is that public behavior, especially in commercial districts and on public transit, is subdued and considerate. Loud, drunk, disruptive behavior is noticed and remembered. The base and the command take this seriously because the US-Japan relationship requires it.
What should I know about Japan's cash culture?
Japan remains significantly more cash-dependent than the US. In major cities and tourist areas, credit and debit card acceptance has improved, but in Yokosuka City, smaller restaurants, many bars, most vending machines, and various local shops will expect cash. ATMs in Japan have hours and US cards don't work at all of them. The reliable exception: 7-Eleven ATMs accept most US-issued cards and are open 24 hours. There are 7-Eleven stores within walking distance of CFAY. The practical approach: withdraw enough yen to cover a day's spending before you leave the base area, and keep a reserve for emergencies. The exchange rate you get at a 7-Eleven ATM with a no-foreign-fee US card is generally competitive. Exchanging cash at currency exchange booths at airports or in the city is convenient but often has a worse rate. USAA and Schwab accounts are particularly popular among service members for overseas ATM use due to their fee reimbursement policies.
Where do I find out about liberty restrictions and buddy system requirements?
Your command. Full stop. CFAY (Commander, Fleet Activities Yokosuka) sets baseline liberty policies per official instructions, and each individual command can and does impose additional restrictions — buddy system requirements, curfews, off-limits areas, and liberty risk reduction requirements — based on their current operational status, recent incidents, or command climate. Off-limits areas are designated by NCIS and the command and are subject to change; they are not posted on a public website. Liberty restrictions in Japan are not static — they can tighten after incidents involving US military anywhere in Japan, not just Yokosuka. Check with your Chief, LPO, or duty officer before liberty call, especially if you are new to the command or newly arrived in-country. The buddy system requirement is real and enforced; getting caught solo when a buddy requirement is in effect is a disciplinary matter, not a paperwork technicality.
