One of the most famous temples in Tohoku, which was founded about 900 years ago. A mountain gate with a total zelkova of 20m in height is set up majestically. The construction of the mountain gate, which can be said to be a symbol of Chōanji, was started in Kansei 8 (1796), but was ordered to be demolished by the Date Domain on two grounds that it was a 17.5m high tower on the use of forbidden zelkova. However, in the fourth year of culture (1807), "Ku Nen-bo Xiu-bai" made an attempt to make an excuse and was acquiesced on condition that the construction could not be continued. Therefore, it has become a gate without doors, without sleeves, and without opening. The present main hall was founded in Meiji 16 (1833). In the precincts, you can see "Oshu Weeping Cherry Blossoms" and "Chōanji Great Ginkou", which are designated as natural monuments of the city.

The station name "Koishihama" was changed to "Koishihama" in 2009, and its romantic name made it famous at once. Inside the waiting room located in the home, there is a lot of lovelorn prayer painting made of scallop shells.
