Kosenji Temple in Sendai City, Miyagi Prefecture, is an historic temple pertaining to the Taira clan. In 1321, after the fall of the Taira clan, a descendant of Taira no Shigemori, known as Komatsu Naidaijin (Inner Minister), disguised himself as a mountain practitioner and came to this village, escaping from his enemies. He founded a temple named Komatsu-dera Temple, where he placed the statue of Amida Nyorai, which was his family’s guardian Buddha, and held memorial services for his deceased ancestors. Later, the temple was changed its name to Kosenji Temple.

The principal object of worship, the statue of Amida Nyorai, was presented to Shigemori by the temple in Auyung in present Ningbo City in China, and treasured as the guardian of the family. After it was enshrined at this temple, it has been named Komatsu Nyorai after Shigemori, and worshipped by local people.  

The temple possesses a lot of cultural properties such as the statue of Idatenjin, the Jizo statue carved by Kaikei and the 12 ancestral tablets including the one for Shigemori, which make us think of the rise and fall of the Taira clan, who once ruled the country.
