Sendaiya

Few Japanese foods are quite as divisive as natto, those sticky, fermented soybeans that have been a breakfast table staple for centuries. Devoted fans are sure to appreciate this Ikejiri-Ohashi shop run by popular Yamanashi natto makers Sendaiya – though even the haters may find themselves won over by unlikely concoctions like natto doughnuts and ice cream (yes, ice cream). There's an eat-in space inside the shop, and if you're in a rush (or a sucker for novelty value), you can also buy your natto from a vending machine.
