Sarushima is the only deserted island in the Tokyo Bay area and is also the biggest natural island. Here you can enjoy many activities such as barbecue, fishing, and strolling around major historical ruins. It takes approximately 30 minutes to get there by boat from the Keikyu Line Yokosuka Chuo Station. (The boats to Sarushima have different capacities, ranging from 80 people to 200 people maximum depending on the season.) This easily accessible sightseeing spot is designated as a National Historic Site.Sarushima was originally a defensive outpost. These brick tunnels, alongside other abandoned structures, are signs of its military history.Before or after getting the boat to Sarushima, we recommend checking out the memorial warship Mikasa, which is in Mikasa Park adjacent to the pier. Mikasa is the oldest surviving steel battleship in the world and is recognized as a Cultural Property of Japan. On board, you will find a great number of historical exhibits. Additionally, on the first floor of the Mikasa Terminal (opened in July 2020), you can buy tickets for the boat to Sarushima, as well as souvenirs and light meals. There is also a tourist information center. We recommend that you visit the Sarushima Visitor Center on the second floor while you wait for the boat. There is no reservation system for boarding, so please arrive well in advance of your desired departure time. The Mikasa Terminal is also the base for landing tours to Tokyo Bay's No.2 Sea Fort.
