Yokosuka: Boat Trip to an Uninhabited Island

A quiet island, a naval city, and a lot of stories. This half-day Yokosuka outing combines the ferry ride to Sarushima Island with forest paths, old military tunnels, a seaside meal at Port Market, and the Memorial Ship Mikasa. I especially like the mix of nature and military history, plus the small group size of no more than six people. The main drawback is that lunch, admission tickets, and some transportation costs are extra, so the advertised price is not the full day’s cost.

The guide is a major part of the appeal. Feedback repeatedly praises Lucy for her warm manner, clear English, and careful explanations, while another booking mentions Kiyoko, suggesting the assigned guide may vary. You should also note the physical and weather limits: there is walking on Sarushima, ferry service depends on conditions, and the outing is not suitable for children under five, babies under one, people prone to seasickness, or anyone over 80.

Key points to know before booking

Yokosuka: Boat Trip to an Uninhabited Island - Key points to know before booking

  • Sarushima is Tokyo Bay’s only natural island: You reach it by a short ferry ride from Yokosuka and spend about two hours exploring its wooded paths, sandy beach, and former military facilities.
  • The island’s military remains are the main attraction: Brick tunnels, barracks, and old power magazines give the walk a serious historical edge.
  • Port Market keeps lunch flexible: You choose your own food and drinks from several options, but the meal is not included in the $70 price.
  • The Memorial Ship Mikasa adds naval context: You explore the upper and middle decks and exhibition rooms after lunch.
  • The group is limited to six people: That makes it easier to ask questions and adjust the pace than on a large city tour.
  • Weather matters: Ferry and cruise services can be canceled or changed, with the guide contacting you the day before.

Starting at Yokosuka-chuo Station at 9:40

Yokosuka: Boat Trip to an Uninhabited Island - Starting at Yokosuka-chuo Station at 9:40

Your meeting point is outside the East Exit of Yokosuka-chuo Station on the Keihin Kyuko Line. The time is fixed at 9:40 in the morning, so I would arrive early enough to find the correct exit without rushing.

From the station, you walk for about 20 minutes to the visitor center. This opening walk helps connect the station area with the port, but it also means you should not treat the ferry as the very first activity. Comfortable shoes are listed as essential, and that advice applies to the station walk, the island paths, and the return walk at the end.

You spend about 30 minutes at the visitor center before boarding the ferry. The provided details do not specify exactly what is covered there, so think of it as an orientation stop rather than a major museum visit. The guide can help place Yokosuka and Sarushima in context before you head out on the water.

The tour is offered in English or Japanese. Several comments praise Lucy’s English and her ability to answer questions, while the provider is Kyoko Kato and one booking refers to Kiyoko. If having a particular guide matters to you, ask about guide assignment before booking rather than assuming one name is guaranteed.

The ferry ride to Sarushima

Yokosuka: Boat Trip to an Uninhabited Island - The ferry ride to Sarushima

The ferry crossing takes about 10 minutes each way. That is short enough for most people who are comfortable on boats, but anyone prone to seasickness should take the warning seriously. The trip is part of the experience, not just a transfer, since the outing takes place on an island that cannot be reached on foot.

The water also gives you a different view of Yokosuka’s naval setting. One particularly useful detail from the tour feedback is that you may see military boats around Yokosuka Bay during the ferry ride. The view depends on the day, but it adds another layer to the city’s connection with the sea.

There is also a reference to naval port cruise tickets, listed at ¥1,000 for adults and ¥500 for children. The main schedule describes ferry crossings rather than a separate cruise, so you should confirm whether a naval port cruise is part of your chosen departure or an optional addition. It is not included in the $70 price.

Walking Sarushima’s tunnels, forest, and beach

Yokosuka: Boat Trip to an Uninhabited Island - Walking Sarushima’s tunnels, forest, and beach

Sarushima is the heart of the outing. You spend around two hours there, with time for a guided walk, sightseeing, photos, and a visit to the former military facilities.

The island’s old brick tunnel is one of the most memorable features. Barracks and power magazines also remain, showing how the island was used by the Japanese military. These are not polished displays arranged behind glass. They are physical traces in the setting where the facilities once served a military purpose, which gives the explanation more weight.

The guide helps you find and understand details that you could easily pass without noticing. One person specifically appreciated being taken to parts of Sarushima that other visitors missed. That is a good reason to choose a guide here, since the island’s interest lies not only in reaching the beach but also in understanding what the structures were for.

The walk also passes through forest. You can look out over Tokyo Bay, take photographs, and spend time on the sandy shore collecting shells. I like this part of the plan because it prevents the morning from becoming a straight military-history lesson. You get ruins, trees, water, and open shore in one compact visit.

The beach is likely to be the most relaxing section of the morning. It gives you room to pause after the tunnels and forest paths, though you should not expect a long beach day. The schedule allows about two hours for the whole island, so the guide will be balancing the walk, explanations, photos, and free time.

The island does require walking on uneven or outdoor paths. The tour does not give a mileage figure or a formal accessibility rating, so anyone with mobility concerns should ask the provider for current conditions before booking. The comfortable-shoes advice is not decorative.

Lunch at Yokosuka Port Market

Yokosuka: Boat Trip to an Uninhabited Island - Lunch at Yokosuka Port Market

After returning by ferry, you walk to Yokosuka Port Market. The transfer from the ferry area is described as a short three-minute walk, and lunch lasts about one hour.

This is a practical choice for a group tour because you are not locked into one set menu. You can choose from a variety of food options and buy your own drinks. That flexibility suits different appetites, but remember that lunch is not included. Your final cost will be higher than the base $70 once you add food, drinks, and admission tickets.

The market’s seaside setting also keeps the day tied to Yokosuka’s port identity. You are not being sent to a generic restaurant far from the water. The one-hour break should be enough for a normal meal, though you may need to keep an eye on the time if you want to browse widely.

This is also the point where the tour’s value becomes easier to judge. You are paying for a licensed local guide, a small group, planning, and guided access to several connected sights. You are not paying for a meal package or all admissions. If you prefer tours where every cost is bundled, this arrangement may feel less convenient. If you prefer choosing your own lunch, it is a sensible setup.

A completely different kind of day out:

Aboard the Memorial Ship Mikasa

Yokosuka: Boat Trip to an Uninhabited Island - Aboard the Memorial Ship Mikasa

The Memorial Ship Mikasa is only about three minutes on foot from Port Market. You spend roughly 40 minutes there, with time for photos, a guided visit, sightseeing, and a walk through the ship.

The Mikasa visit focuses on the Russo-Japanese War. You explore the upper and middle decks before visiting exhibition rooms. This creates a useful progression: first you see the ship as a physical naval object, then you get more explanation through displays.

Admission is separate. The listed prices are ¥600 for adults, ¥500 for seniors, and free for children. Since the tour already covers Sarushima’s military remains, the Mikasa adds a second setting for understanding Japan’s military and naval past. The two stops are different enough to work well together: Sarushima is an outdoor site with ruins, while Mikasa is a preserved ship with decks and exhibition spaces.

Forty minutes is enough for an introduction, but it is not an unhurried museum visit. If you like reading every panel slowly, you may want more time than the schedule provides. The guide’s explanations can help you focus on the most important parts, especially if this is your first visit to Yokosuka.

The tour finishes with about a 20-minute walk back to Yokosuka-chuo Station. From the meeting point to the return, the whole activity lasts about 330 minutes, or five and a half hours. That makes it a substantial half-day outing rather than a quick side trip.

What the guide adds to the experience

Yokosuka: Boat Trip to an Uninhabited Island - What the guide adds to the experience

The strongest praise is directed at the guides, especially Lucy. She is described as friendly, easy to talk with, attentive to small details, and able to explain both Yokosuka’s past and current naval activity. Several comments also emphasize that she uses books, information, and other aids to make the places easier to understand.

That matters on Sarushima. Without context, a tunnel is simply a tunnel and an old building is simply an old building. A guide can explain how the island’s military facilities fit together and point out routes or details you might miss alone.

The personal tone is another advantage of a group limited to six. You can ask questions without waiting for a microphone or trying to catch a guide in a crowd. The comments also describe the atmosphere as friendly, with some people feeling as if they were spending the day with a local acquaintance rather than following a large organized group.

Guide assignment is the one uncertainty. The provider is Kyoko Kato, but the names Lucy and Kiyoko appear in the booking feedback. That does not mean the service is inconsistent, but it does mean you should confirm who will lead your departure if language ability or personal style is important to you.

Price, extra costs, and overall value

Yokosuka: Boat Trip to an Uninhabited Island - Price, extra costs, and overall value

The base price is $70 per person. For a five-and-a-half-hour small-group tour with a licensed local guide, that can be reasonable, especially if you value interpretation and local navigation more than a low-cost self-guided day.

You should budget separately for:

  • Lunch and drinks at Port Market
  • Memorial Ship Mikasa admission: ¥600 adult, ¥500 senior, children free
  • Any applicable naval port cruise ticket: ¥1,000 adult and ¥500 child
  • Transportation costs to and from the meeting point

The ferry is part of the planned route, but the supplied pricing information does not clearly state whether every ferry or cruise charge is included. Ask before paying if you want a precise total.

The value is strongest for visitors staying in Tokyo who want a different type of day outside the city center. You get nature, coastal views, military remains, local food, and a historic naval ship without arranging each piece yourself. The value is weaker if you want a very slow beach visit, a long museum session, or an all-inclusive price.

Who should book this Yokosuka outing?

Yokosuka: Boat Trip to an Uninhabited Island - Who should book this Yokosuka outing?

I would recommend it to adults and older children who enjoy history but do not want to spend the whole day indoors. It also suits couples, solo visitors, and small groups who want to ask questions and move at a more personal pace.

It is a particularly good match for someone interested in naval history. The ferry, military boats, Sarushima facilities, and Mikasa all point toward Yokosuka’s role as a port city with a strong military identity.

Nature lovers get a fair share of the day, too. The forest walk, bay views, and sandy beach provide a welcome break from Tokyo’s buildings. One person’s favorite elements included the beach, ferry views, and a local Yokosuka street connection, showing how the outing can appeal to people with different interests.

I would be cautious if you get seasick, dislike outdoor walking, or want complete control over your schedule. The ferry and weather can disrupt the plan, and the tour is not suitable for children under five, babies under one, or people over 80. Services are weather-dependent, with the guide contacting you the day before if conditions affect the ferry or cruise.

Cancellation is flexible up to 24 hours before departure for a full refund, and you can reserve now and pay later. That helps when your Japan plans are still shifting, though it does not remove the need to check weather conditions before the outing.

Should you book it?

Yokosuka: Boat Trip to an Uninhabited Island - Should you book it?

Book this tour if you want a guided introduction to Yokosuka that combines Sarushima’s military ruins with the Memorial Ship Mikasa and a flexible local lunch. The small group, short ferry crossings, and strong guide feedback make it a more personal choice than a standard bus excursion.

Skip it if you are looking for a beach-only trip, dislike boats, or need a fully inclusive price. For the right visitor, the best reason to go is the combination: you see Yokosuka from the water, walk through a wooded island with military remains, eat by the port, and finish aboard a historic warship. That is a lot of variety in five and a half hours.
