新心流- the characters literally mean “New Heart/Mind School”. This name was chosen to reflect the fact that you should approach your training with a new, or fresh, heart and mind everyday. Throughout this essay Shinshin-ryu is also referred to as Sekiguchi Shinshin-ryu and Shinshin Sekiguchi-ryu. In the past these names, along with a few others, all referred to the same school. At present the school based in Gifu-ken is called Shinshin-ryu Iaijutsu or Shinshin Sekiguchi-ryu Iaijutsu. The school based in Wakayama is called Sekiguchi-ryu Jujutsu. The school based in Kumamoto is called Sekiguchi-ryu Battojutsu.
