This is a traditional festival that has continued for over 1400 years. The most famous part of it is the "barter exchange," where in the past, people exchanged sea and mountain products before dawn using the phrase "kaenkaeー." Currently, the event organized by the Mankoji City Preservation Association and local residents allows people to enjoy bartering. Why not bring something joyful and participate in the barter exchange? During the event, stalls line up, making it bustling and lively.
