Sweet Potato Expo

Spend winter in Japan the right way at the Sweet Potato Expo at Keyaki Hiroba plaza located just outside Saitama Super Arena. From big-time yakiimo makers to independent food trucks, discover 18 of the best sweet potato vendors and vote for your favourite in the National Yakiimo Grand Prix. Eat sweet potatoes the traditional way – straight out of the stone oven – or try them in soup, chips, pies and croquettes. Whole sweet potatoes are available at all stalls, but we recommend getting the tasting set, which nets you six kinds of baked sweet potatoes from three different vendors for a discounted price.
