Daiba Park is a 15-minute walk from Odaiba Kaihin Kōen Station in Tokyo, built on the site of the Edo shogunate's third battery. The Rainbow Bridge is visible from the park, and visitors can walk around along the stone walls and descend into the sunken area at the center. In that central sunken area, remains of the jinya site, gunpowder magazine site, and hearth site are present. At night there are no streetlights, so the stairs and the ground underfoot are dark.
