Yotsushima Jetty
Yotsushima, or the Four Islands, is a rare “Jetty Dive” spot in Japan, located around Ruzaoan Island. Entry is from a ferry pier, just 5 minutes by boat. The harbor has parking, water, and flush toilets. The reefs host abundant marine life, with frequent sightings of large schools of fish.
You’ll be amazed by the charm and size of the four islands’ stars—Kinjiro the Asian sheepshead wrasse and Hanatare the red seabream. This summer-only site is open July–October.
