@Benny47464727 I started to question the narrative when I went to the Kofun museum and saw the tools they had used to move and carve the sarcophagus, soft copper. It seemed impossible. I wonder if the tombs were there before the Jomon people and later re-used as tombs.
@OpsoFacto@TheProjectUnity Ishi no Hลden (็ณใฎๅฎๆฎฟ) it's in Takasago, Hyogo prefecture. Not sure about the rope or eagle head but it's a shrine about a 10 minutes ride from the nearest train station
