Floods broke out in Tsubamesanjo, destroying the city with much loss of life and property.

The government at the time invited artisans from Edo to tell the people of Tsubamesanjo about the production technology used to make 'wakugi', and that technology became a sideline for the farmers and gave them a new life.

Afterwards the area expanded

Into making agricultural equipment for developing new fields. Eventually, the industry shifted to the forging of carpentry tools, knives and the processing of copperware.
