Hahajima Tourism Association, in the Oki Port Passenger Terminal (Inside the passenger terminal)
This is the best place to get tourist information for Hahajima. Come here to find out about lodging, eating, guided tours, and more. If you are planning to go into the Kiyomigaoka Limestone Cave, come here first to borrow keys and helmets. If you are going to climb Mt. Chibusa, stop here first to buy a (300-yen) summit kit; then stop by again after you get down to pick up your commemorative certificate.
Wakihama Nagisa Park
(5 minute walk from the passenger waiting room)
A beach area where the locals often come to take a break. During spring, 20 or 30 whitetip reef sharks gather in the shallows here. Don't be scared; they are usually quite well-mannered. A part of the beach is set aside as a protected spawning area for green turtles; if you come during spawning season, you will see 20 or 30 of these lovely creatures, too.
