Yakiimo Fest 2026 in Tokyo and Osaka will offer a free ¥800 food voucher to the first 100 visitors each day during its October 30–November 8 run. The autumn event brings together specialty vendors serving classic roasted sweet potatoes and creative sweet potato dishes.
For travelers mapping a casual food route in Nakano or around Osaka Castle, the festival offers two convenient venues. Tokyo is held at Shiki-no-Mori Park in Nakano, while the Osaka edition takes place at Sun Plaza in Osaka Castle Park. Admission is free at both venues, but food and drinks cost extra.
Visitors can exchange one digital coupon for an ¥800 food voucher at the advance-ticket exchange counter. The wider early-bird campaign can provide up to ¥8,000 in vouchers, while advance ticket bundles start at ¥4,700 through the official app and ePlus.
