Fushimi Castle
Shigenaga was attacked by Umanosuke who already possessed a number of trophy heads. Shigenaga was attacked with the Honjō Masamune which split his helmet, but he survived and took the sword as a prize. The blade had a number of chips from the great battle but was still usable. It was kept by Shigenaga until he was sent to Fushimi Castle around 1592.
