Koyanagi and Hirano Family Residence

This three-story house built in the first half of the nineteenth century is the largest iguraya-style house in Shiotatsu. The iguraya style is characterized by hipped and gabled roofs covered with tiles. Due to its large size, the interior is now divided into two sections where the family stores are run.

During the Edo period, the families ran a kimono shop and opened a branch store across the street. In 1910, the building was converted into a bank for a time.
