Kirara Beach and Yamaguchi Bay are resting places for migratory birds heading to Southeast Asia from Siberia and Kamchatka, as well as those from Mongolia and China heading for Shikoku and Kyūshū. Millions of wild birds visit Kirara Beach every year. The climate is mild, the waters are clear, the air is clean, and the beach is abundant in greenery. There is a natural park on the site, where wildlife living on Kirara Beach is preserved.
