What is it?

Oni manju binds cubes of sweet potato with a modest flour, rice-flour and sugar batter, then steams rough mounds. Protruding potato cubes evoke an oni's horns or iron club.

It is a home-style sweet across Aichi and the wider Tokai area. Names include imo-uiro around Atsuta and imo-manju or imo-man; unlike ordinary manju, the standard form does not enclose bean paste.

History and local context

Sugar draws moisture from one-centimeter potato cubes; flour and rice flour are mixed into that liquid before portions are steamed on paper.

Aichi records that it was once homemade and could supplement scarce rice, while commercial sales helped the name oni manju become standard.

How to enjoy it

Eat freshly steamed or at room temperature to compare fluffy potato with chewy batter.

Because it is moist and perishable, follow the shop's same-day or refrigerated storage instructions.

Availability varies by maker, season, and destination.
