This thatched-roof home is Ogimachi's finest -- not surprising, as it belonged to the wealthy Wada family, which served as the region's top officials. Still occupied by the Wada family, the 300-year-old house boasts carved transoms, painted sliding doors, lacquerware passed down through generations, a family altar, and tatami rooms overlooking a private garden. Upstairs you can see how the heavy roof beams are held together using only rope (no nails were used), as well as containers once used in silkworm cultivation.
