Sohugan

This dive site, Sohugan, is a remote and enigmatic oceanic pinnacle located approximately 570km south of Tokyo, strategically positioned between the Ogasawara Islands and Hachijojima Island. Rising dramatically from a depth of 2500 meters, with its peak at 99 meters above sea level, this strangely shaped rock offers a unique and challenging dive experience. Access requires an arduous 20-hour journey by charter boat, emphasizing its isolated and pristine nature. Navigation around this exposed rock would primarily involve drift diving along its walls and slopes, exploring the rich pelagic ecosystem it supports in the deep ocean. Sohugan is a magnet for large marine life. Divers can expect to encounter an abundance of migratory fish, including bigeye trevally, longnose trevally, kappores, yellowtail, and impressive large bluefin tuna. Crabs are also noted inhabitants. The site is particularly renowned for its diverse shark species. Seasonally, it offers the rare opportunity to witness majestic humpback and beaked whales, making it a prime destination for encounters with megafauna. While specific coral types are not mentioned, the focus is clearly on the pelagic food chain that thrives around this isolated structure. The best time to visit Sohugan would likely coincide with the migratory patterns of its pelagic inhabitants and whales, though specific seasonal details are not provided. This advanced-only site is a highlight for divers seeking large animal encounters and dramatic underwater landscapes. Due to its remote location and potentially strong currents, thorough planning, experienced dive guides, and excellent diving skills are essential. Freedivers with advanced capabilities may also find this site rewarding for its large animal encounters, but should be prepared for challenging conditions.
