The genealogy was written as follows: the first lord of the Yanagawa domain, Tachibana Muneshige, sailed out from Osaka port on September 17, 1600 after the West squad that Muneshige’s army joined was defeated in the battle of Sekigahara; when he passed Najima-jo Castle of Lord Kobayakawa, who switched sides to the East squad during the battle, he prepared for fighting against the Kobayakawa’s army; but the defenders of the castle hadn’t heard of their lord’s betrayal and gave the permission for the Muneshige’s army to pass the castle; Muneshige then reached the border of his domain where several hundred of his vassals came from Yanagawa-jo Castle to escort him, and finally arrived his castle with them on September 23.
