Ohenro-San is an adventure video game released in 2003 by PIN Change. The game was released only in Japan.
Its a simulation game based on the Ohenro pilgrimage, a 1,400 kilometer journey around the 88 temples of Shikoku region of japan. Due to the disk size only 23 of the temples on the route are represented in the GC version. As you visit each temple you are meant to offer prayers & collect a special seal that goes in your ohenro journal each one is unique to each temple. Its sort of a souviner of your visit.
