High-altitude Lake Motosu shore dive featuring submerged trees, altitude procedures, and a calm freshwater setting under Mount Fuji.
About Haunted Mansion
This freshwater dive site in a high-altitude lake is centered on a massive sunken tree, whose algae-covered branches create a spooky, mansion-like silhouette underwater. Diving here is considered a high-altitude dive (around 900 m elevation) and calls for careful buoyancy control. The submerged trees and plants host a mix of freshwater fish and small macro life.
