Hoshi Imo and Yaki Imo : Classic Japanese Sweet Potato Snacks

When it comes to Japanese sweet potato snacks, I used to buy “Yaki-Imo (焼き芋)” from a catering vehicle that passed my house almost every evening during the winter season.

Yaki-Imo (焼き芋)

Yaki Imo

Yaki Imo is a classic Japanese sweet potato snack typically cooked in burning fallen leaves with aluminum foil or roasted in heated small pebbles.

The Yaki Imo snack is usually unseasoned and makes the most of the natural sweetness of the sweet potato.

When the sweet potato is cooked using heated small pebbles, it is generally called “Ishi-Yaki Imo (石焼きいも)”, which is mainly offered by the catering vehicle in the winter season.

Hoshi-Imo (干し芋)

As with Yaki Imo, “Hoshi-Imo (干し芋)” is a classic snack in Japan made of Japanese sweet potato “Satsuma Imo (サツマイモ)”.

Hoshi Imo is similar in taste to Yaki Imo because the sweet potato snack is also unseasoned. But Hoshi Imo is different from Yaki Imo in the cooking method. The sweet potato is steamed first, then dried in the sun.

The formal name of Hoshi Imo is “Kiriboshi Kansho (切干甘藷)”, and the dried steamed sweet potato is also called “Kansou Imo (乾燥芋)”, “Kipposhi (きっぽし)” or “Imo-Kachi (いもかち)”.


Hoshi Imo is available in various shapes in Japan, but it often has a square bar shape, making the snack easy to eat.
