What is Kosenji Temple? | An Ancient Temple Related to the Taira Clan
Kosenji Temple is a Soto Zen temple located at 67 Ninowayama, Nagafukuro, Akiu-machi, Taihaku-ku, Sendai City, Miyagi Prefecture. It is close to the center of Akiu-machi and is built on a south-facing mountainside overlooking the Natori River valley. Currently belonging to the Soto Zen sect, its predecessor was Komatsu-ji Temple of the Tendai sect, and it has evolved into its current form through centuries of historical changes.
The temple’s name, “Kosen-ji,” was adopted during a major renovation undertaken during the time of Akiho Katsumori, the 17th head of the Akiho clan. Before that, it was known as “Komatsu-ji.”
History of Kosen-ji Temple | From Komatsu-ji to Kosen-ji
Founding of Komatsu-ji Temple and the Legend of the Heike Fugitives
Komatsu-ji Temple, the predecessor of Kosen-ji Temple, is deeply connected to the legend of the Heike fugitives. According to tradition, a warrior believed to be a descendant of Taira no Shigemori (known as Komatsu Naifu), a son of Taira no Kiyomori, fled to this area after the fall of the Heike clan. He enshrined the “Amida Buddha statue,” the family’s guardian deity, and founded Komatsu-ji Temple to pray for the souls of the Heike clan.
The name Komatsu-ji Temple is thought to originate from the fact that Taira no Shigemori was called “Komatsu Naifu,” indicating a deep connection with the Taira clan.
Transition from Tendai to Soto Zen
In its early days, Komatsu-ji Temple belonged to the Tendai sect as a branch temple of Yoshida Shureisai (also written as Shurokusai) in Takadate, Natori City. However, with the passage of time, its sect changed, and it now belongs to the Soto Zen sect. While historical records are limited regarding the exact timing and circumstances of this sect change, it is highly likely that it occurred during the turbulent period from the Sengoku period to the early Edo period.
Deep Connection with the Akiho Clan
An essential aspect of the history of Kosen-ji Temple is its relationship with the Akiho clan, a powerful samurai family in the region. The Akiho clan ruled the Akiho region and had a deep connection with Kosen-ji Temple (then Komatsu-ji Temple).
In particular, during the time of Akiho Katsumori, the 17th head of the Akiho clan, a large-scale renovation of the temple was carried out, and at this time, the temple’s name was changed from “Komatsu-ji” to “Kosen-ji.” This marked a significant turning point in the temple’s history.
Akiho Sadamori and the Giant Crape Myrtle Tree
In front of the main hall of Kosen-ji Temple stands a giant crape myrtle tree. It is said that this tree was donated by Akiho Sadamori, the 19th head of the Akiho clan, to commemorate his departure for the Summer Siege of Osaka (1615). With a history of over 400 years, this crape myrtle tree blooms magnificently in the summer and has become a symbol of Kosen-ji Temple.
Akiho Sadamori was a samurai who served Date Masamune and participated in the Siege of Osaka. The fact that he donated the crape myrtle tree to Kosen-ji Temple, his family temple, before going into battle is a valuable historical document illustrating the relationship between samurai and temples at that time.
Highlights of the Temple Grounds

As mentioned above, the giant crape myrtle tree in front of the main hall is a major highlight of Kosenji Temple.

It holds great historical value and can be considered a living witness to the relationship between the Akiu clan and Kosenji Temple.
