Katsuya Tamaki (勝也 玉木 - カツヤ タマキ) was born in Osaka, Japan, in 1970. He began training under the direct guidance of his father, Katsumi Tamaki, from an early age. This training started before Shinjin-ryu was formally named, reflecting the traditional reality that the principles and methods of an art often exist long before they are formally identified as a system.
In 1982, he moved with his parents to England, one year after his father’s arrival in 1981. His training continued uninterrupted throughout this period, remaining rooted in close personal instruction, practical application, and long-term immersion rather than structured curriculum or external influence.
Raised within the Shinjin-ryu family line and shaped by both Japanese and Western contexts, Katsuya Tamaki represents a direct continuation of the system as it developed and was transmitted. His senior rank reflects decades of continuous practice and responsibility within Shinjin-ryu and was formally recognised through evaluation by a panel of senior practitioners, including family and external representation, to ensure legitimacy and continuity.
He stands as the natural inheritor of Shinjin-ryu, carrying forward its principles with continuity rather than reinterpretation.
