Fukuno Shichirouemon Masakatsu (福野七郎右衛門正勝) studied the Yagyū Shinkage-ryū (柳生新陰流) Heihō (兵法 - war method, strategy) under Yagyū Sekishūsai Taira-no-Munetoshi (柳生石舟斎平宗厳 ) and became a ‘Tatsujin’ (達人 – master expert) of the Yagyū Shinkage-ryū. As such the Yagyū Shinkage-ryū can be considered as one of the root lineages, or pillars upon which the Ryōi Shintō-ryū (良移心当流) was founded.
