Sweet potatoes are a very popular seasonal food during Japan's autumn months, and they are served up in a variety of ways. The Aichi Sweet Potato Expo is a four-day event that celebrates the humble root vegetable, with around 20 booths selling a myriad of tasty treats featuring it.
This is a ticketed event, with admission priced at 500 JPY for advance tickets or 600 JPY on the day. More information on advance tickets can be found on the Lawson website here. Please note that food and drink purchases are charged separately.
