IMPORTANT INFORMATION
Welcome to Diving in Izu
Izu is the best choice if you're looking for a dive spot that offers beautiful underwater scenery and wildlife, without having to travel far away from Tokyo. It's a popular spot for divers based in Tokyo and sees lots of visitors on weekends and weekdays throughout the year. Both shore and boat dives are available, as well as transport to a great number of excellent dive sites. We can recommend the best spot for you, based upon your experience level and the ocean conditions.  All the guides here at East Dive are licensed PADI Instructors who have multiple years of exploring these dive spots under their belts and are happy to share their local knowledge with you.

KUMOMI/SOUTH IZU
Kumomi is very popular spot for people who are interested in cave diving. There are many dive sites in the bay that feature caves, and a few on the outside too. The dive boats here are equipped with a life-style exit, which means that 4 divers can be pulled up at once. Not only are the boats being comfortable, but the water is also exceptionally warm. Thanks to the warm currents moving up the Pacific Ocean, the water can reach 27°C/80.6°F in the summer. Visibility in the summer and the autumn is usually greater than 20 meters (65ft).
One unique feature we call the "Cave of H". Although truth be told, it's more like a underwater maze than a cave. Don't be intimidated; our experts can guide you through here easily. If you're interested in even larger caves, ask us about the giant underwater cave.

What kinds of underwater life can you see on the Izu Peninsula?
