The only way to reach the islands is by taking the Ogasawara Maru ferry from Takeshiba Pier in Tokyo, which takes approximately 24 hours each way. The ferry runs once every three to six days, so most visits require at least a week-long commitment. Once you arrive at Chichijima's Futami Port, the World Heritage Center is easily accessible on the island. Plan your trip carefully around the ferry schedule to ensure you have adequate time to explore.
