The Edo period "Settsu Meisho Zue Taisei" (Illustrated Guide to Famous Places in Settsu) states, "The Kokuzo Hall at Taiheiji Temple enshrines Kokuzo Bodhisattva. Visitors visit without interruption, especially on March 13th, flocks of 13-year-old children visit the temple to pray for wisdom and blessings. This is called the "Jusan Mairi" (Thirteen Mairi). Since ancient times, Taiheiji has attracted devotees as the "Temple of Thirteen Mairi," and many children have been granted the wisdom and blessings of the immeasurable Kokuzo Bodhisattva. Dating back to the 16th century, Taiheiji was said to have been a part of Shitennoji, but fell into disrepair. In 1663, the monk Chozan Ginetsu rebuilt the temple and opened it as a Soto Zen temple. The temple grounds also house the Kitayama Acala, a designated cultural property of Osaka City, where the famous physician Kitayama Juan of the Genroku period (1600-1868) was buried as a sokushinbutsu (self-mummified monk). This statue also attracts a constant stream of pilgrims.
