Irabu and Shimoji are the headline boat-diving coast. W-Arch is relatively shallower, while Shimoji landmarks Antoni Gaudi, Satans Palace and Toriike have deeper, sometimes current-swept or overhead routes. Local providers such as Irabujima Sumankaikuu list guided fun dives, but each site and path require individual screening.
W-Arch (Irabu)
A famous heart-like arch on the Irabu side, often a more approachable scenic topography dive when routed as open water.
Antoni Gaudi (Shimoji)
Interconnected natural openings form a cathedral-like structure; published tourism profile reaches about 33 m and occasionally strong currents.
Satans Palace / Mao no Kyuden (Shimoji)
A cavern-ceiling light-shaft scene, listed to roughly 27 m with moderate to strong current.
Toriike / Tooriike (Shimoji)
The celebrated freshwater-saltwater transition and sea-to-pond connection are associated with serious depth and enclosed passage.
Checklist opérateur
Use verified, current dive businesses and ask for a non-penetration alternative before paying. Do not assume Yabiji scuba access because an offshore snorkel operator is taking passengers. Irabujima Sumankaikuu advertises winter closure from Dec 24, 2026 through Jan 31, 2027 and February on request. Operators may cancel or swap sites even in favored months; a wreck mention in older marketing is not enough to establish a current wreck-penetration product. Last-dive-to-flight buffers should follow DAN guidance and the stricter of operator advice or personal dive profile.
