24 hours on liner ship Ogasawara-maru from Takeshiba Pier to Chichijima island, Futami Port. 5 minutes by car or 30 minutes on foot from the port.
The Ogasawara Marine Center (also lovingly known as the "Turtle Center") has come a long way since its inception in 1982. Specializing in the research and conservation of the local wildlife, particularly humpback whales and sea turtles, the center has a wealth of information available for you to browse.
Throughout the year, the Marine Center both takes in and rehabilitates ill or injured sea turtles, as well as helping to raise young turtles from eggs through to their release into the wild. If simply taking pictures of their adorable charges isn't enough for you, consider signing up for their two-hour special educational course where you can get up close and personal with a sea turtle. You can also sponsor baby turtles, and receive written updates (with pictures) from the staff for ten months.
