The Hashihaka kofun (箸墓古墳) is a megalithic tomb (kofun) located in Sakurai, Nara Prefecture, Japan. The Hashihaka kofun is considered to be the first large keyhole-shaped kofun constructed in Japan and is associated with the emergence of the Yamato Kingship. The name Hashihaka translates as "chopstick grave" and refers to a mythical love affair between Yamato Totohi Momoso and the kami of sacred Mount Miwa, which ended with the princess stabbing herself to death with a chopstick.
