国指定重要文化財 岩瀬家
Built in the mid-18th century over a span of 8 years, the Iwase House is the largest Gassho-style house and a testament to the power of the Kaga clan. The use of zelkova wood in the house was specially permitted because it was a hub for the niter industry, with niter being both produced and collected from the people here to offer to the Kaga clan as a tax. The house was nationally designated as an Important Cultural Property in 1958.
