A wakizashi made by Kotetsu, a swordsmith who flourished during the Edo period. He's handed down in the Ikeda household, the lord of Tottori. The origin of his name is the image of Urashima Tarou carved on his blade. With his innocent personality, he can be friends with anyone. That's why, whether it's a turtle or a dragon king or whatever else, come!
