Origins and History
The origins of Aizen-in are traditionally traced to 816, during the early Heian period. According to temple tradition, the Buddhist monk Kūkai, also known as Kōbō Daishi, was traveling through Shikoku when he sensed a sacred presence at this location. He is said to have carved an image of Fudō Myōō himself and enshrined it as the principal deity.
The temple was originally known as Amidaji. In 1921, it merged with another temple called Aizen-in, which had stood within the grounds of Tairyū-ji, the 21st temple on the Shikoku pilgrimage. Following this merger, it adopted its present name.
Faith, Folklore, and the Akazawa Shinano-no-kami Mausoleum
The temple grounds contain the mausoleum of Akazawa Shinano-no-kami Takamasa, a feudal lord associated with Bansai Castle during Japan’s Warring States period. According to historical tradition, he was killed at the Battle of Nakatomigawa in 1582, during Chōsokabe Motochika’s invasion of Awa Province.
The mausoleum has a distinctive local tradition: people pray here for relief from ailments affecting the lower half of the body. This belief is linked to a story that Akazawa lost a battle after the cord of his straw sandal broke. In keeping with this tradition, people whose prayers are answered offer straw sandals to the temple. A particularly large pair of sandals can be seen on the grounds, making this custom an unusual feature of a visit.
A Unique Pilgrimage Stamp
Aizen-in is known for a distinctive form of pilgrimage inscription. While temple stamps and calligraphy are generally written with a traditional brush, Aizen-in uses a special technique called hakegaki bonji, in which Sanskrit characters are written with a broad brush. This method is considered unique among the temples associated with the Shikoku 88-Temple Pilgrimage.
If the head priest is unavailable, visitors may receive a prepared inscription instead. For pilgrims collecting temple stamps and calligraphy as a record of their journey, this unusual practice is a special part of the temple’s identity.
Highlights of the Temple Grounds
Niō Gate
The temple entrance is known as the Niō Gate. Statues of the Kongō Rikishi guardian figures stand on either side, traditionally protecting the sacred grounds and those who enter.
Main Hall
The main hall enshrines Fudō Myōō, along with images of Aizen Myōō and Dainichi Nyorai. These Buddhist deities are associated with different aspects of spiritual protection, wisdom, and devotion. Visitors come to pray for blessings such as protection from misfortune and success in personal relationships.
Daishi Hall
The Daishi Hall houses a statue of Kūkai. As a place dedicated to the revered founder of Shingon Buddhism, it is an important stop for pilgrims following the Shikoku 88-Temple route.
Akazawa Shinano-no-kami Mausoleum
The mausoleum of Akazawa Shinano-no-kami is one of the temple’s most distinctive historic features. On the wooded hillside behind it, visitors can also find a group of stone monuments believed to commemorate his retainers. Together, these remains offer a glimpse into the turbulent history of the Warring States period.
Bell Tower
The temple’s bell tower houses a bell that visitors may ring. The sound of the bell carries across the grounds, and ringing it is traditionally associated with dispelling worldly desires and creating a moment of spiritual reflection.
The Eighty-Eight Stone Buddhas
Behind the temple, on Mount Fudō, a series of 88 stone Buddhist statues represents the temples of the Shikoku pilgrimage. This miniature pilgrimage route allows visitors to encounter the symbolism of the famous circuit in a quiet natural setting.

Beside the access road to Aizen-in is Nato Waterside Park, a small, landscaped green space featuring ancient lotus varieties, water lilies, and flowering trees. Its peaceful paths make it a pleasant place for a leisurely stroll and a chance to enjoy the natural surroundings before or after visiting the temple.
