When Chōi-sai returned home, he offered prayers to the deities of both Katori Shrine and Kashima Shrine, the latter being a famous local shrine in nearby Ibaraki Prefecture, where shrine officials themselves reputedly practised a form of swordsmanship, called 'Hitotsu no Tachi' (the solitary sword). Even today the Kashima Shrine training hall attracts Kendo practitioners from around the world, and the chief object of interest for visitors is the shrine's sacred sword. Supplementing his considerable skills with assorted weaponry, Chōi-sai was also an expert in Musō Jikiden ryū "yawaragi", holding the position of seventh Headmaster in the history of that ryū.
