Spicy Udon at Onsen Town Togura-Kamiyamada
Kohaku : 古波久(こはく)

Udon Noodles with the Nefariously Spicy Nezumi Daikon Radish.

Northern Nagano


Kohaku is an izakaya (pub) in Onsen Town Togura-Kamiyamada that specializes in "Oshibori Udon". This local favorite uses the spicy Nezumi Daikon radish which is grated and squeezed ('shibori'). Miso paste is added to the juice to tame it down, and you dip the fat udon noodles in and eat. Kohaku serves oshibori udon in a big kettle and hangs it on a hook and guests sit around the 'irori' hearth for their meal.


Fields around Onsen Town Togura-Kamiyamada and neighboring Sakaki Village often have rocky soil which stunts the growth of the daikon radishes. The variety known as "nezumi daikon" ("nezumi" means 'mouse') is short and fat with a little tail, resembling its namesake. Perhaps due to their growth being stunted, nezumi daikon radish's spicy potency is enhanced.
Many restaurants in the area offer oshibori udon, but Kohaku is the most famous and its interior with the irori hearths provides a traditional Japanese setting.
