Yokosuka Adventure: Explore Uninhabited Island & Naval Cruise

Yokosuka Adventure: Explore Uninhabited Island & Naval Cruise

When you think of Japan’s Kanagawa Prefecture, images of bustling Tokyo or serene Kamakura might come to mind. But for a truly engaging day that blends history, nature, and naval sights, the Yokosuka Adventure tour offers a fantastic mix. Priced at around $91.76 per person, this 6.5-hour experience takes you from the historic ruins of Sarushima Island to a lively port market, topped off with a scenic harbor cruise along Tokyo Bay.

What we love about this tour is its combination of accessible history and authentic local flavor. The visit to Sarushima’s old military fortifications and brick tunnels offers a tangible sense of Japan’s military past, while the seafood and navy-themed sights give a glimpse into Yokosuka’s modern naval significance. Plus, the English-translated harbor cruise allows for easy understanding of the impressive battleships and submarines docked nearby.

A possible consideration? The tour involves moderate physical activity—climbing around the island, walking in the harbor, and some standing during the cruise—so it’s best suited for travelers with a decent level of mobility. Also, the ferry fee to Sarushima and admission costs for the cruise aren’t included in the price, so budget accordingly.

This tour is perfect for history buffs, seafood lovers, and maritime enthusiasts who want an authentic Yokosuka experience away from typical tourist crowds. Families, solo travelers, or couples looking for a balanced mix of history and scenic beauty will find this outing holds a lot of appeal.

An In-Depth Look at the Yokosuka Adventure Tour

Starting Point: Yokosuka-ch Station

The tour kicks off at Yokosuka-ch Station at 9:30 am, a convenient spot close to public transportation. From there, a short walk brings you to the ferry pier where your adventure begins. The small group size—since it’s a private tour—means more interaction with your guide, making the experience feel personal and relaxed.

Visiting Sarushima Island: The Historic Military Outpost

The first stop is Sarushima, known locally as Monkey Island. The ferry ride across Tokyo Bay offers immediate views of the bay and, on clear days, a glimpse of Mt. Fuji—a bonus that many travelers cherish. This natural island once served as a military base from the late 19th to mid-20th centuries, and remnants of gun batteries, barracks, and brick tunnels still evoke the island’s strategic importance.

What makes Sarushima particularly special is how accessible its history is. We loved the way the guide, Lucy, explained the significance of each site, making the ruins feel alive rather than just old stones. As you walk through the forest trails, you’ll find birdwatching opportunities and scenic overlooks of Tokyo Bay from the island’s highest points.

The beach area provides a relaxing spot to collect shells and soak in the peaceful atmosphere. The reviews rave about the beautiful scenery and the tranquility of the island, which offers a stark contrast to Japan’s bustling city life. One reviewer noted, “I loved the history and tranquility of Sarushima. The scenery was so beautiful. Especially I enjoyed the beach with clear water.”

Lunch at Yokosuka Port Market

After exploring the island, you’ll return to the mainland and head to Yokosuka Port Market. The market is a lively hub of local produce, seafood, and quick bites. Here, you can choose from navy-style burgers, hearty ramen, fresh seafood, and even craft beers—something for every taste.

The market is not just about food but also about soaking up local portside ambiance. Travelers often comment on the quality of the fresh ingredients and the variety of options, making it an excellent chance to indulge in authentic Yokosuka flavors. One reviewer shared, “The seafood and navy burger were delicious, and it was fun to see the local produce.”

Naval Harbor Cruise: A Unique Marine Perspective

No Yokosuka tour would be complete without a harbor cruise—and this one is a special treat. It lasts about two hours and offers up-close views of U.S. Navy battleships, submarines, and the Japanese Maritime Self-Defense Force vessels.

What’s particularly helpful is the English translation provided by your guide, ensuring you don’t miss out on the fascinating details. You’ll get a sense of the naval significance of Yokosuka, which has been Japan’s key naval base since the post-war period.

Travelers have described the cruise as “more like a personal tour,” especially with just one or two other participants. The views are stunning, and seeing the ships up close gives a real sense of military might and maritime history. A reviewer remarked, “Lucy was very personable and interested in each of us, and the cruise was a highlight of the day.”

Overall Value and Experience

While the cost doesn’t include ferry, admission fees, or cruise tickets, the overall value is considerable—you’re getting a full day of history, scenery, and local culture. The inclusion of a licensed guide and the personalized feel of the experience make it worthwhile.
