Hahajima is accessible only by the Hahajima-maru Ferry from Chichijima Island, located approximately 40 kilometers to the north. The journey takes about two hours and costs around 6,000 yen one way. Ferry tickets cannot be reserved in advance and are sold approximately one hour before departure on the day of travel. The ferry typically makes one daily round trip, departing in the morning and returning in the afternoon, though schedules vary when the Ogasawara-maru arrives from Tokyo. Note that the ferry does not operate the day after the Ogasawara-maru departs Tokyo.
The Hahajima Tourism Association operates a tourist information desk at Oki Port, where all ferries arrive. The association provides information on accommodations, guided tours, activities, and the island's environmental regulations. They can assist with booking pensions and lodgings, arranging nature tours, and explaining the strict rules for protecting Hahajima's UNESCO World Natural Heritage site status. The association also coordinates with local guides for whale watching, snorkeling, hiking, and cave exploration at the Kiyomigaoka karst region.
Due to Hahajima's status as part of a UNESCO World Natural Heritage site, visitors must follow strict environmental protection rules. Camping and off-trail hiking are completely prohibited throughout the island to preserve the fragile ecosystem. Visitors must not import any seeds or alien species, and are prohibited from collecting or harming local plants and wildlife. Much of the island is restricted access to protect endemic species found nowhere else on Earth. Visitors are encouraged to use human-powered transportation like walking or bicycles whenever possible.
Hahajima has limited accommodation options, primarily consisting of small family-run pensions and guesthouses located near Oki Port. The Tourism Association's website lists approximately 10 lodging facilities offering various styles, including individual rooms and dormitory-type accommodations. Some provide meals while others have kitchen facilities or offer no meal plans. Reservations must be made in advance, and securing accommodation before arrival is strongly advised due to limited capacity. The island has no luxury hotels, and only a handful of establishments accept credit cards, so visitors should bring sufficient cash.
Hahajima has minimal infrastructure befitting its remote location and small population. The island has three supermarkets that typically close around 18:00, offering basic groceries, drinks, and instant foods. Dining options outside of accommodations are very limited, with only two restaurants on the island. Banking services are available through a JA bank with a postal ATM at Oki Port that accepts international credit and debit cards. There is no public transportation system, so visitors explore on foot or by rental bicycle, scooter, or car. The island has no bars, clubs, or entertainment venues, maintaining its character as a peaceful, nature-focused destination.
