Main article starts here.


Niemonjima floating in the sea at the front of Futomi beach in Kamogawa in Southern Boso Peninsula is possessed by a private owner.
The 30,000 m2 island is known by its scenic beauty and the legends of Minamoto Yoritomo and Nichiren, a Buddhist monk.
The island has a residence made in the Tokugawa period and Bashozuka, as well as stone tablets inscribed with haiku composed by Mizuhara Oushi, Tomiyasu Fusei, and Suzuki Masajo.
The island is designated as a place of scenic beauty by Chiba Prefecture and selected as one of Shin Nihon Hyakkei (newly-selected 100 beautiful sceneries in Japan).
Only one residence possessed by Hirano Niemon has been standing since more than 800 years ago.
You can go to the island on a rare old-style boat with two paddles within about five minutes. You can walk around the entire island within about 50 minutes.
