Tourist Information centers in Chichijima Island, Ogasawara Islands in Tokyo
Ogasawara Commerce and Tourist Association provides guided tours and accommodation information. Advanced reservations are preferable, but you can find available guided tours here.
Ogasawara Visitor Center exhibits the history and ecosystem of Ogasawara Island. They protect wildlife too. When we visited the center, they captured a waterfowl and released her.
Ogasawara Summer Festival happens at the open space near the B-ship in every August. You can enjoy Bon Dance, fireworks, releasing baby turtles and a music event. I had never seen such a huge fireworks display in front of me before.
Ogasawara Summer Festival is not a tourist information center, but we could mingle with local people to know the islands atmosphere.
