Shishido Baiken

Shishido Baiken (宍戸梅軒, also 宍戸某 Shishido Bō) is the name of a Japanese swordsman believed to have been active in the early years of the Edo period (1603-1868). Legend has it that Baiken was a skilled practitioner of the kusarigama (a metal chain attached to a kama and a weight, also known as the chain and sickle), and around the year 1607 he fought a duel the swordsman Miyamoto Musashi in which he was killed.

It is debatable if Baiken actually existed or not. The first record of Musashi's duel with Shishido Bō is in the Nitenki (二天記) written in 1776. The name Shishido Baiken appears to first appear in Eiji Yoshikawa's Musashi. If fictional, he may have been based on Shishido Ietoshi (宍戸家俊).
