Dives are possible directly from the beach, and are beginner-friendly as well.
Because the beaches here are composed of pebbles rather than finer sand, the waters remain beautifully clear and unclouded.
Although Nagato's coastline faces the famously rough Sea of Japan, the protective shape of the bay keeps the waters here relatively calm and easy for diving.
Underwater caves are accessible in a number of locations, and are popular among divers for their otherworldly beauty.

Fascinating Sea Life
When southern winds are strong, upwelling occurs in the bay's waters, pulling cooler, deeper ocean waters towards the surface.
With this exchange of surface waters for nutrient-rich deep ocean waters, every so often sightings of deep sea creatures are made off Omijima Island.
This phenomenon produces large amounts of plankton and fish, ensuring the waters are teeming with life, and divers are often able to make interesting new acquaintances below the surface!

One of Japan's Preeminent Diving Locations
Omijima's rare and unusual sealife makes it popular amongst ocean photographers, too,
who gather from all over the country for photo dives at this leading scuba location.
Conducting dives without going through the diving shop first is strictly prohibited.
