Things to Do in Yokosuka: A Local Read on the Navy Port, the Burger and the Island

Start with a date, because it reframes most of the things to do in Yokosuka. In 1872, four years into the Meiji era, the naval base here adopted British-style curry to fight beriberi among its sailors — a rationing decision, not a culinary one. The city revived that recipe as a local brand in 1999, working from a 1908 navy cookbook. That single line of history is the key to the whole town: almost everything worth doing in Yokosuka is a working naval port quietly turned into something you can eat, board or walk through. This isn't pretty-postcard Japan an hour from Tokyo; it's a place that earns its character, and the trick is reading which parts are real and which are gift-shop.

What makes Yokosuka different — and what the food really is

On the ground, what I notice is that Yokosuka's signature dishes aren't invented marketing — they're licensed. The Yokosuka Navy Burger is a French-bread bun around a thick, coarse-ground 100% beef patty, a postwar inheritance from US Navy mess culture. The Cherry Cheesecake and the burger recipes were handed to local restaurants directly by the US Navy Yokosuka base, which is why the versions here taste like a 1950s American diner rather than a Japanese approximation of one.

That provenance is the thing to plan a meal around. On Dobuita Street, TSUNAMI is one of the few places that serves all three staples — Navy Burger, Navy Curry and Cherry Cheesecake — in a single sitting, useful if you have one lunch to spend. HONEYBEE, going since 1968 and on Tabelog's top-100 hamburger list, builds its 'Yokosuka Gourmet Plate' from the same trio. Yokosuka Shell runs the base-supplied burger and New-York-style cheesecake recipes alongside the navy curry. The honest caveat: these are hearty, calorie-dense plates built for sailors — split one combination plate between two and you'll still walk away full.

Getting there and the smart route

Access is the easy part. From Shinagawa, the Keikyu Main Line reaches Yokosuka-Chuo in under an hour, and most of the sights are walkable or a short local bus from there. The JR Yokosuka Line is the alternative — Tokyo Station to Yokosuka Station in about an hour and twenty minutes — but for a day built around Dobuita Street, the Mikasa waterfront and the ferry pier, Keikyu's Yokosuka-Chuo puts you closer to the action.

The route the day argues for is anchored on one timetable, not on a list of sights. The Sarushima ferry runs hourly from Mikasa Pier — first boat out at 8:30, last return at 17:00, leaving on the :30 outbound and the :45 return — and the crossing takes about ten minutes. Build the day backwards from the boat you want to catch. Do Dobuita Street and a navy-burger lunch on either side of an island run, and keep the Mikasa battleship and Verny Park as the flexible filler around the ferry slot, since they don't run on a clock.

Experiences beyond the checklist

The standout is Sarushima — 'Monkey Island' — Tokyo Bay's only uninhabited natural island, ten minutes off Mikasa Pier for ¥1,300 round-trip (¥650 for elementary-age children). What you walk into is a set of Meiji-era brick tunnels and fort ruins swallowed by greenery; people reliably call it Ghibli-like, and for once the comparison fits, because the moss and the arched red brick really do read like a film set. There are beaches and BBQ areas too, but the ruins are the reason to go. Mind the timetable: with the last return at 17:00, an early-afternoon crossing is the safe play.

Back on the mainland, the Battleship Mikasa at Mikasa Park is a walk-aboard museum ship — Admiral Togo's flagship from the 1904–05 Russo-Japanese War, billed as the oldest surviving steel battleship in the world. The Yokosuka Naval Port Cruise departs nearby and is the genuinely unusual one: a boat tour threading an active US Navy and JMSDF base, passing destroyers, submarines and the occasional aircraft carrier up close. For quieter hours, Verny Park's rose garden holds around 1,300 bushes of roughly 130 varieties beside the naval port, peaking twice a year — the Spring Rose Festa in May, the Fall Rose Festa in October — part of why May and June are the recommended windows. And Kannonzaki, a short hop south, has Japan's first Western-style lighthouse (begun in 1868) with coastal and forest trails running through the woods to the Yokosuka Museum of Art.

Dobuita Street, read honestly

Dobuita Street is the atmospheric heart, a strip beside the US base lined with sukajan (souvenir-jacket) shops, bars and diners that have served both American and Japanese sailors for decades. The embroidered sukajan jackets are the real local craft here, and the genuine shops sit among newer tourist-grade ones — worth a slow walk to tell them apart. It's also where the burger diners cluster, so the street doubles as your lunch sorted. Personally, I think the key to Dobuita is treating it as a place to linger and people-watch rather than a photo stop; its appeal is texture, and texture takes time.

The quiet hours: a working hypothesis

Here's the contrarian read. Yokosuka's whole tourism economy is a salvage operation — a working military port that turned its constraints (a US base, a beriberi ration, decommissioned forts) into things visitors pay to experience. That origin is also its scheduling tell. The crowds and the heat are worst in midsummer and on festival weekends, while the genuinely good windows are May–June and late September, when the weather is mild and the queues thin. This is still a hypothesis, but the implication is concrete: Yokosuka rewards the off-season day-tripper far more than the peak-season one. Come on a mild shoulder-season weekday, catch an early ferry to the island, eat the burger the base actually taught the town to make, and the port becomes the offbeat day it's best at being.
