Sakai clan
Nyoirin-ji was built approximately 1,000 years ago by a Shingon priest. In 1470 the temple was transferred to the Kempon Hokke-shū sect of Nichiren Buddhism by Sadataka Sakai (1435 - 15220) of the Sakai clan, lord of nearby Kazusa Castle. The Hondō of Nyoirin-ji was constructed in 1711 after the previous structure was destroyed by fire.
