This dive site, Sanchin, is situated within the Kerama Islands, an hour's boat ride from Naha Port in Okinawa, Japan. It is celebrated for its exceptionally clear waters and captivating underwater landscape, which features a delightful array of crevices and inviting swim-throughs. The site's relatively shallow average depth and excellent visibility make navigation straightforward, ideal for exploring its vibrant reef structures.
Sanchin is teeming with a diverse community of tropical fish, including lively triggerfish, charming clownfish, and schools of blue damsels. Divers frequently encounter graceful sea turtles and unique sea snakes. The site is a spectacle of color, adorned with extensive formations of both vibrant soft and hard corals that create a thriving ecosystem for countless small marine creatures.
The optimal time to dive Sanchin is generally during Okinawa's warm season, from spring to autumn, when conditions are calm and water temperatures are comfortable. Its appealing combination of shallow depths, clear visibility, and rich marine biodiversity makes it perfectly suited for all levels of scuba divers, and also highly enjoyable for snorkelers and freedivers. The picturesque environment offers fantastic opportunities for both wide-angle landscape photography and detailed macro shots of the intricate coral life.
