Ōtsukayama Kofun

Ōtsukayama Kofun is an ancient keyhole-shaped burial mound in Aizuwakamatsu that dates to the 6th century. The site features a rectangular front section connected to a large circular rear portion, creating the distinctive form typical of important tombs from this era.

The mound was built in the 6th century and reflects a period when regional groups in Japan maintained distinct identities. Its construction marks a time of growing complexity in settlement patterns across the country.

Archaeological investigations uncovered 279 items in the southern burial area, including bronze mirrors, magatama beads, swords, armor, and ceremonial objects.

The site is easily accessible on foot from the nearby area and can be explored freely by visitors. Bringing weather-appropriate clothing is helpful since the mound is outdoors with no protective structures.

Inside the mound are two wooden sarcophagus-like structures that are rare in local archaeology. The interior walls bear traces of red pigment, revealing the considerable effort devoted to the burial chamber's decoration.
