Yokosuka: Boat Trip to an Uninhabited Island

Trade Tokyo’s crowded streets for sea air and old military ruins. This small-group Yokosuka tour combines a ferry ride to Sarushima, a forest walk, and a visit to the Memorial Ship Mikasa, making it a strong choice if you want nature and naval history in one half-day outing. I especially like the contrast between Sarushima’s brick tunnels and sandy beach, and the chance to eat at the waterfront Port Market instead of being tied to a fixed restaurant.

The guide is another major strength. Lucy is praised for her warm manner, clear English, and detailed explanations, while one Japanese guest names Kiyoko as an excellent guide. The main drawback is that the $70 price does not include lunch, ferry-related costs, Mikasa admission, or your transportation to Yokosuka, so the final bill will be higher.

Key Points Before You Book

• Sarushima is Tokyo Bay’s only natural island, with former military tunnels, barracks, power magazines, woodland, and a beach.
• The tour is limited to six people, which makes it easier to ask questions and keep a relaxed walking pace.
• The guide-led history is the heart of the experience, especially if you want help making sense of Sarushima’s military remains and Yokosuka’s naval role.
• Port Market gives you lunch freedom, with several food choices rather than one fixed menu.
• Mikasa adds a second historical stop, with access to the upper and middle decks and exhibition rooms.
• Weather matters, since ferry and cruise services can be canceled or changed in poor conditions.

Why Yokosuka Makes a Good Day Away From Tokyo

Yokosuka gives you a very different view of Japan from the usual Tokyo route. The city is tied closely to the sea and military activity, yet this outing also brings you into a forested island setting with open water and a sandy shore.

You meet at 9:40 am outside the east exit of Yokosuka-chuo Station on the Keihin Kyuko Line. From there, you walk about 20 minutes to the visitor center. That opening walk helps you get oriented, but it also means you should arrive ready to walk rather than expecting the ferry terminal to be right beside the station.

The full experience lasts about 330 minutes, or five and a half hours. It includes several walks, two short ferry rides, time on Sarushima, lunch, and the Mikasa visit. I would treat it as an active half-day tour, not a quick excursion you can fit into a narrow gap between train connections.

The group size is capped at six people. That matters here because Sarushima has paths, ruins, and small details that are easy to miss when you move in a large crowd. A small group also gives you a better chance to ask about the old military facilities, nearby naval activity, or local places in Yokosuka.

Starting at Yokosuka-chuo Station

The morning meeting point is straightforward: outside the east exit of Yokosuka-chuo Station. The guide speaks English and Japanese, and the experience provider is Kyoko Kato. The supplied feedback repeatedly praises Lucy, while one review names Kiyoko, so it is sensible to confirm which guide will lead your date.

The walk to the visitor center takes about 20 minutes. This is not just dead time. It gives the guide room to explain Yokosuka and point out local details before you reach the water.

A visitor center stop follows and lasts around 30 minutes. The exact content is not specified, but it serves as the first orientation point before you board the ferry. If you like to understand a place before seeing its sights, this pause should help put Sarushima’s ruins into context.

Wear comfortable shoes from the start. You will walk through town, across the island, and back through Yokosuka later in the day. The paths on Sarushima include forest walking and access to historic structures, so this is not a purely paved sightseeing route.

Crossing Tokyo Bay to Sarushima

The ferry ride to Sarushima takes about 10 minutes each way. The crossing is short, but it is one of the pleasures of the day. You get a water-level view of the bay and a clear break from the city.

The sea crossing also explains why weather planning matters. Ferry and cruise services depend on conditions, and the guide is expected to contact you the day before if weather affects the plan. If you are prone to seasickness, this experience is specifically not recommended for you.

The trip information also lists tickets for a naval port cruise as an extra cost, priced at ¥1,000 for adults and ¥500 for children. The planned route described here uses the ferry to Sarushima, not a separate cruise, so ask the guide to clarify if a naval cruise is part of your date or simply an optional cost connected with the wider Yokosuka program.

Walking Sarushima’s Brick Tunnels and Beach

Sarushima is the main event. The island visit lasts about two hours and includes a guided tour, sightseeing, walking, and time for photographs.

The island is described as the only natural island in Tokyo Bay. Its importance is not only scenic. You walk among remains of former military facilities, including a brick tunnel, barracks, and power magazines used by the old Japanese military.

These structures give the walk a clear sense of purpose. Instead of simply circling an island for views, you move between trees, old brickwork, and coastal spaces while learning how the site was used. The guide’s explanations are especially useful here because ruins without context can look like little more than attractive old walls.

Several people specifically praise Lucy’s explanations of Sarushima and Yokosuka. One guest says the guide helped the group reach parts of the island that other visitors missed. You should not assume every path or stop will be available on every date, but a local guide can help you see more than a self-guided walk would.

The natural side of the island is just as important. You walk through the forest, look across Tokyo Bay, and reach a sandy beach where you can collect shells. The beach gives the tour a lighter rhythm after the military remains. I like that the experience does not treat Sarushima as only a war-history site. You get ruins, trees, sea views, and a little room to slow down.

Conditions can change the feel of the walk. In warm or wet weather, forest paths may be less comfortable, and the beach can be exposed. Comfortable footwear is essential. Children under five are not accepted, and the experience is not suitable for babies under one, people over 80, or anyone prone to seasickness.

Lunch at Yokosuka Port Market

After returning by ferry, you walk to Yokosuka Port Market, where you have about one hour for lunch. Food and drinks are not included, but the open choice is useful. You can select from several menus rather than paying for a meal you may not want.

The market sits by the sea, so lunch keeps the waterfront theme going. It also gives you a practical break before the final historical stop. After two hours of walking on Sarushima, a proper meal and a place to sit are welcome.

This part is less structured than the guided sections. That can be a plus if you like choosing your own food, but you should budget for lunch separately. The $70 tour price is not the full cost of the day.

One review also praises the guide for pointing out local food and lesser-known places around Yokosuka. That kind of local help can make the market stop more useful than simply being told where to eat. Still, the information provided does not specify individual vendors or dishes, so you should expect choice rather than a planned tasting menu.

Inside the Memorial Ship Mikasa

The final major stop is the Memorial Ship Mikasa, only about three minutes on foot from the market. You have roughly 40 minutes for photographs, a guided visit, sightseeing, and walking through the ship.

Mikasa is tied to the Russo-Japanese War, and the visit focuses on that period. You can explore the upper and middle decks before visiting the exhibition rooms. This is a good companion to Sarushima because it shifts the story from coastal defenses and island facilities to a major naval vessel.

Admission is extra: ¥600 for adults, ¥500 for seniors, and free for children. The short visit means you will not explore every corner at a leisurely pace, but 40 minutes is enough to see the principal areas and receive an introduction to the ship’s role.

I would pay close attention to the guide here. A warship can be visually impressive but confusing without a clear explanation of dates, people, and purpose. The strongest praise for this experience focuses on the guide’s ability to explain Yokosuka’s past and current naval setting in clear English.

After Mikasa, you walk about 20 minutes back to Yokosuka-chuo Station. That final walk brings the total walking time to roughly 43 minutes outside the island, before counting the Sarushima paths themselves.

How Much Value Does the $70 Price Offer?

At $70 per person, this is not a bargain if you only want a ferry ride and a beach walk. You also pay for lunch and drinks, admission to Mikasa, and your own transportation to Yokosuka. The separate naval port cruise charge may also apply if that activity is added to your day.

The value improves if you want a guide. You are paying for a small group, local orientation, English or Japanese service, historical interpretation, and help connecting several Yokosuka sights in one route. Sarushima’s military remains are far more meaningful when someone explains what the tunnels, barracks, and power magazines were for.

The small group is another reason the price can make sense. With up to six people, the guide can answer questions and adjust explanations more easily than on a large bus tour. Several accounts praise Lucy for making the day feel friendly and personal, with one guest describing the experience as more like being led by a friend.

The price is less attractive for independent visitors who are comfortable arranging the ferry, market, and Mikasa on their own. In that case, the tour’s main benefit is convenience and interpretation, not transportation savings.

The Guides Make the Difference

The clearest pattern in the feedback is the praise for the guides. Lucy is described as friendly, easy to talk with, generous with information, and able to explain both historical subjects and current naval activity. One guest appreciated that she used books and other aids to make the places easier to understand.

Another person praised her attention to detail and said the group reached different parts of Sarushima than they might have found alone. That is exactly the sort of help that matters on an island where the best experience depends on noticing small structures and understanding their purpose.

The names are not fully consistent. Most comments refer to Lucy, while one refers to Kiyoko, and the provider is Kyoko Kato. If having a particular guide matters to you, confirm the guide’s name before booking. The useful point is that the guide quality receives strong praise across the available feedback.

The tour is offered in English and Japanese. You should still expect some historical vocabulary, especially at Mikasa, but the comments describe the English service as clear and easy to follow.

Practical Details for a Smooth Day

Book with the weather in mind. The ferry and cruise services depend on sea conditions, and the guide contacts you the day before if there is a change. Flexible plans are wise if Sarushima is the main reason you are visiting Yokosuka.

You can cancel up to 24 hours before the activity for a full refund. Reserve-now, pay-later booking is also available, which helps if your wider Japan schedule is still changing.

Bring comfortable shoes and plan to carry enough money for lunch, drinks, Mikasa admission, and any applicable transport or cruise fees. The experience does not include your transportation to the meeting point.

This tour suits adults, older children, history fans, nature lovers, and anyone who wants a smaller coastal outing from Tokyo. It is less suitable if you dislike walking, get seasick, need a fully indoor activity, or want a simple sightseeing ride with little historical explanation.

Should You Book the Sarushima and Mikasa Tour?

I would book this tour if you want a compact Yokosuka introduction with real local guidance. The mix is unusually good: ferry travel, forest paths, military ruins, a beach, a market lunch, and a historic warship, all in about five and a half hours.

I would skip it if your budget is tight or if you prefer to explore independently. The added costs matter, and the ferry schedule depends on the weather.

For most people who want a break from central Tokyo, the tour offers a worthwhile change of pace. You get open water and nature on Sarushima, serious history at Mikasa, and a guide who can make both places easier to understand. Confirm the guide, check the weather, and allow extra money beyond the $70 headline price.
