Asamushi-Natsudomari Prefectural Natural Park
Overlooking Mutsu Bay, Asamushi Onsen showcases the islands of Yunoshima, Hadakajima, and Kamomejima scattered in the ocean. Yunoshima is home to thousands of Asian fawnlilies, a plant whose leaves and flowers here are nearly double the size of those seen elsewhere. Protruding into Mutsu Bay is the Natsudomari Peninsula, which is about 45 km all around. On the eastern side of the peninsula lies Asadokoro Beach, a registered Special Natural Monument that attracts thousands of migrating swans each year. One may forget the passage of time while admiring the incredible view and graceful swans.
