About this center
PADI 5 Star Resort on Aka Island inside Kerama Marine Park. On-site accommodation with 5-min boat rides to world-class dive sites.
Marine House Seasir Aka is a PADI 5 Star Dive Resort located directly on Aka Island in the heart of the Kerama National Marine Park. Unlike day-trip operations from Naha, Seasir Aka offers the unique advantage of being based within the marine park itself, with dive sites just 5 to 10 minutes by boat. This proximity means more time underwater and access to early morning and late afternoon dives when marine life is most active.
The resort provides on-site accommodation just a minute's walk from the beach, allowing guests to combine a tropical island stay with world-class diving. The surrounding waters feature over 200 species of coral, resident sea turtle populations, and remarkable visibility that frequently exceeds 40 meters. Divers can explore dramatic coral walls, sandy channels, and coral gardens teeming with tropical fish.
PADI courses from beginner to professional level are available, and the resort's relaxed island atmosphere makes it a popular choice for multi-day diving holidays. The small island setting provides an authentic Japanese island experience far from the bustle of Naha, with stunning beaches and crystal-clear snorkeling accessible right from shore.
