Ōtsukayama Kofun, Ancient keyhole-shaped burial mound in Aizuwakamatsu, Japan
The Ōtsukayama Kofun extends 114 meters in length with a rectangular section of 54 meters and a circular rear portion measuring 70 meters in diameter.
Constructed during the 6th century AD, this tomb represents connections between regional tribes and the emerging Yamato political structure in early Japanese history.
Archaeological investigations uncovered 279 items in the southern burial area, including bronze mirrors, magatama beads, swords, armor, and ceremonial objects.
The burial mound stands at a distance of 30 minutes by foot from Aizu-Wakamatsu Station on the JR East Banetsu West Line.
The tomb contains two wooden bamboo-shaped sarcophagi and features walls covered in vermillion pigment, using over 10 kilograms of cinnabar on the clay floor.
