Akiu Great Falls

This dive site, Akiu Great Falls (Akiu Ootaki), located about an hour from Sendai, Japan, offers one of the world's rarest freshwater waterfall diving experiences. Divers plunge into the basin directly beneath a majestic 55-meter waterfall, experiencing intense vibrations from the falling water. Navigation is straightforward within the contained basin, primarily exploring the immediate area around the waterfall's impact zone. While not teeming with marine life due to its freshwater nature, the site allows observation of various freshwater river fish. Expect to see species such as char, rockfish, trout, white-tailed bream, and swordfish. Lucky divers might even encounter cherry salmon. Occasionally, frogs and other small freshwater animals can also be spotted within the basin's ecosystem. The best time to visit for diving or freediving would likely be during periods of stable weather, avoiding heavy rainfall that could impact visibility or current strength. This unique site is ideal for those seeking an unusual dive experience rather than abundant marine biodiversity. Its shallow depths make it very accessible for beginners and highly suitable for freedivers and snorkelers keen to explore the freshwater environment and feel the power of the waterfall up close.
