Sanbe soba became widely known due to some circumstances, for example, that it was introduced on the menu at the community bathhouse in Sanbe Hot Springs that opened in March 1877 and when the Sanbe Highlands became the Army Exercise Area in the late Meiji period whereby it was eaten by the soldiers there.
