In the morning, we visit the war historical sites on the only natural island in Tokyo Bay. The remains of the facilities, such as the brick tunnel, the barracks, and power magazines used by the old Japanese military. Walk in the forest, overlooking Tokyo Bay collecting shells on the sandy beach on the island.
After returning from the island, we have lunch at the Port Market by the sea, choosing from a variety of menus. Then, we wander down Dobuita Street to discover military goods and Japanese souvenirs.
The final treat is a harbour cruise, where we view the battleships and submarines of the American Navy and Japanese Maritime Self-Defense Forces.
