A trip to monkey island

#getgoing2025 Sarushima, which floats off the coast of Yokosuka Port, is the only natural island in Tokyo Bay and the largest uninhabited island in the bay with a circumference of about 1.6 kilometres. Since it is located at the entrance of Tokyo Bay, it has been a key point for the Defence of the capital since the end of the Edo period. It is now a casual leisure island that can be crossed in about 10 minutes by a dedicated boat. When you enter the inside of the island, a huge brick remains appear. It is designated as a national historic site because valuable structures such as brick remains built in the French structure (Flanders structure) remain.
