Tà Âgà  Tà Âbee Shigekata (æÂ±é· è¤堵衠éÂÂä½Â, 1560- 1643) was a direct student of Terasaka Yakuro Masatsune, the third headmaster of the Tenshinsho Jigen Ryu (èªé¡Â, Jigen), and of Marume Nagayoshi, founder of the Taisha Ryu.Tà Âgà  was a samurai from the Satsuma domain credited with founding the Jigen Ryu (示ç¾, Jigen).
Tà Âgà  Shigekata was born in 1560 in Satsuma, Japan (current day Kagoshima Prefecture). He had his first battlefield experience in 1577 at the Battle of Mimigawa when he was seventeen years old. In his twenties, Tà Âgà  came under the tutelage of Marume Nagayoshi, the founder the Taisha Ryu and quickly mastered the system where he was then initiated into the gokui (secrets) of the tradition.
In 1588, Tà Âgà  accompanied Shimazu Yoshihiro (Lord of the Satsuma domain) to Kyoto where he met a Buddhist monk that went by the name of Zenkitsu. (Zenkitsu's given name was Terasaka Yakuro Masatsune) Zenkitsu was the chief priest of Tenneiji Temple and third headmaster of the Tenshisho Jigen Ryu. Under Zenkitsu's guidance, Tà Âgà  mastered the Tenshinsho Jigen Ryu in less than a year.
Tà Âgà  would return to Satsuma where he trained in the Tenshinsho Jigen Ryu for three years before combining his studies to create the Jigen Ryu.
Tà Âgà ÂâÂÂs renaming of his school was based on an insight he gained by performing religious austerities (shugyo). While meditating on a section of the Lotus Sutra, Shigekata became inspired by the phrase âÂÂjigen jintsurikiâ (示ç¾ç¥ÂéÂÂÃ¥ÂÂ, a sudden revelation of divine power). He therefore changed the characters of Jigen Ryu from jigen (èªé¡Â, self-power revelation) to a set of characters from the Buddhist text- jigen (示ç¾, sudden revelation). In this sense, jigen indicates the use by a buddha of a âÂÂmanifest formâ in order to teach sentient beings.
At the age of 44, Tà Âgà  became the chief swordsmanship instructor for the Satsuma domain.
Tà Âgà  died in 1643.
