Sokodo is Hachijojima's clear-water shore reef at Mimata Arch.
Sokodo is one of Hachijojima's signature shore dives, known for Hachijo blue water, an embankment entry, and the Mimata Arch. The shallows are friendly enough for beginners and snorkelers, while the arch and nearby reef add enough structure for experienced divers to stay interested. Green turtles are a real highlight here, along with snappers, striped anemonefish, and seasonal cuttlefish action. It is a calm, high-clarity site that works best when you want an easy beach dive with real island character.

Key Hazards
Safety Notes
Treat Mimata Arch as an overhead feature and keep buoyancy tight around the embankment entry and reef top. The site is easiest when the sea is calm and the visibility is up.
Access Restrictions
Shore entry is from the embankment; check tides and weather before you go.
Legal Notes
Follow local beach and harbor rules.
Community notes to help plan your visit.
Scuba Diving
A relaxed shore dive to a reef and arch, good for beginners who want a clear-water site and enough structure to stay interesting.
Freediving
The shallow look near the entry can suit calm-water freedive practice, but the site is mainly a scuba and snorkel shore dive.
Snorkeling
A very good snorkel choice near the shore and around the arch on calm days, with turtles often a highlight.
