What you can eat
Around 200 sweet potato items are on offer from 31 shops. They come from Kagoshima, Kagawa, Tokushima, Okayama, Mie, Aichi, Kyoto, Nara, Ibaraki and more, so it works as a quick tour of regional sweet potato styles without leaving Yokohama.
Roasted sweet potato (yaki-imo) is the centrepiece. You can compare varieties from fluffy and dry to moist and sticky, and there are dedicated yaki-imo shops, dried sweet potato (hoshi-imo) shops and sweet potato dessert shops. Beyond that, expect sweet potato pastries, bread, doughnuts, taiyaki and tempura.
Prices for each menu item are not listed here. Check the official event page for the latest menus.

| Session 2 | 12:00 to 13:45 |
| Session 3 | 14:00 to 15:45 |
