Sarushima

Next to the Sanli Memorial is the ferry terminal to Ape Island, which is a 10-minute one-way round trip every hour. The island is the only uninhabited island in the Gulf of Tokyo. It has been built as a military fortress. There are many gun shelters, caves, tunnels and other military purposes on the island, but it has not been used in actual combat. The island itself is not big enough. If you browse roughly for about 40 minutes, the beach near the dock is good, many tourists come back to wash water in summer, there are BBQ shops on the island, it should be great to come for a day and a half to relax.

The only natural island floating in Tokyo Bay, the largest uninhabited island in the bay. It was a "fortress island" with a battery and ammunition as a key to protecting Tokyo Bay. It is an island with the sea, beach, and rocky shore, as it was left in the same way as it was at that time, where you can freely stroll around the island.
