This very interesting tomb of an ancient ruler is about 1600 years old, and was beautifully restored in the 1980s. This 100 m-long tomb is perched high on a hill just east of the Shinkansen line and opposite the Anzu no Sato Agri Park. At the base of the site is Shinano no Sato Historic Park, depicting a village from the same era, and the Nagano Prefectural History Museum. Both are worth a visit, although English information is minimal.
