What is it?

Soboro natto is an Ibaraki food that mixes fermented soybeans with strips of salted dried daikon and soy-based seasoning. The sticky beans and crisp-chewy radish create a stronger texture than plain natto.

It may also be called shoboro natto or oboro natto. Saltiness and sweetness vary by household and commercial producer.

History and local context

Farm households around Mito combined two preserved foods into a practical side dish. The wider fame of Mito natto later helped make the mixture a recognizable Ibaraki souvenir.

How to enjoy it

Serve a small portion over hot rice, in ochazuke, or with sake. Stir gently first so the daikon remains distinct instead of disappearing into the beans.

Availability varies by maker, season, and destination.
