During the Edo period (1600~1868) there was a samurai family that lived in Gonohe called the Maruko family. The residence of this family has been preserved and it remains a valuable example of late-Edo era architecture. It was designated as a Prefectural Treasure in 2001 for several unique architectural features not found elsewhere inside the prefecture.

 In 1993 the front gate, boarded fence, well, hedges, garden, etc. were faithfully restored by using drawings of the house that had been made long ago. Inside the living quarters of the house old books, pictures, and other everyday items have been put on display. Furthermore, the grounds of the residence is said to be home to the oldest Oak tree in all of Japan. At an estimated age of 750 years, the tree was designated a prefectural natural monument in 1996.
