Things to do · Destination Guide
Volcanic shore dives, seasonal offshore encounters and hot-spring towns, planned one coast at a time.
Pick an activity mode to compare signature sites, skill fit, and gear planning notes before you lock your trip.
Build your scuba trip around a specific coast and entry type. Izu Oceanic Park and Futo anchor the east; Osezaki and Koganezaki offer managed western shore options; Kumomi adds boat-accessed rock formations; Mikomoto is a specialist southern drift outing. Atami's wreck has a deeper profile and separate prerequisites. The range is broad, but no single certification or calendar makes every site suitable.
