Tatsukushi Diving Center

Set within Ashizuri-Uwakai National Park in Tosashimizu City, Kochi Prefecture, the Tatsukushi Sea offers a special diving experience shaped by crystal-clear waters, strange rock formations, and rich biodiversity. Fed by the warm Kuroshio Current, its dynamic underwater terrain is scattered with crevasses across the open ocean — a landscape made for divers who love reading the topography.

What you'll find beneath the surface

The marine life here shifts beautifully with the seasons. Divers can observe migratory fish, colourful tropical species, and over 107 types of coral, alongside sharks, whales, turtles, eels, molluscs and crustaceans. Migratory fish are most active from summer to autumn, while more than 400 kinds of sea slugs appear from winter into spring. When sunlight filters through the clear water and casts its shadows, the moment is truly breathtaking.

As a PADI Resort with 2 PADI instructors offering scuba diving, Tatsukushi Diving Center suits divers drawn to dramatic topography and seasonal marine variety. English and Japanese are spoken, with free Wi-Fi, parking, and equipment sales on site.
