Founded in 1976, this onigiri shop chain has 16 directly operated stores centered in Yokkaichi City, Mie Prefecture.

When asked "What do the citizens of Yokkaichi think of Momotaro? the answer is "onigiri," which is the soul food of Yokkaichi residents. At Kubota's main store, whose trademark is the oversized Momotaro doll, there is a giant peach sculpture on top of the main store building, and five times a day the peach opens and Momotaro comes out from inside!
