Comment: This keyhole-shaped tomb was built entirely from dirt on the top of Hakusanbira, a hill 145 m in height. From Higashinomiya Shrine, which is nestled amidst a deciduous forest to the south of the tomb’s front, one can enjoy a magnificent view that befits a royal tomb of the ancient kingdom of Kuna.
