Held every year in mid-October at the Shikinomori Lifelong Learning Center (Amikake, Tambasasayama City). Many groups, mainly from the Tannan area, sell Tannan area specialties such as Tambasasayama tea, Sumiyama burdocks, and Tennai sweet potatoes (taro), as well as black edamame and chestnuts, and hold a variety of food and beverage booths where you can enjoy gourmet foods made from the flavors of autumn. There will also be stage events, allowing visitors to fully enjoy Tambasasayama in autumn.
