Training Background

Early Influences

My first martial arts practice was in Shukokai, a hard style of Japanese Karatedo that was developed from Shito-ryu and Goju-ryu. From 1989 to 2005, I practiced a form of modern self-defense oriented jujutsu (goshin-jutsu) that blended techniques drawn from Aikido and Shorinji Kempo in an attempt to provide a well-rounded approach to urban close quarter combat.

I began training in the internal martial art of Bagua Zhang in 2004, and it was in 2005, while visiting the Gassan Dai Jinja ( 月山大 神社 ) shrine on Mt. Haguro in the Dewa Sanzan ( 出羽三山 ) area of Yamagata Prefecture and the Hagurosan Kōtakuji Shōzenin ( 羽黒山荒沢 寺正善院) in Haguro-machi, that I decided to commit my full efforts towards learning Chinese Internal martial arts, even if it meant giving up teaching modern jujutsu.

Internal Martial Arts

I currently practice Internal Martial Arts under the North American Yin Cheng Gong Fa (YCGF) organization of Zhang Yun. My practice is focused on developing a level of mastery in Hebei Style Xing Yi Quan, Yin Style Bagua Zhang, and Northern Wu Style Taijiquan. As part of this training, I practice straight sword (Taiji Jian, Bagua Jian, and Xingyi Jian), two-handed broadsword (Taiji Dao and Tian Gang Dao), and spear (Taiji Qiang). These are all as taught by Zhang Yun as part of North American YCGF.

Koryu Kenjutsu

I have also been fortunate to learn portions of the curriculum of several classical Japanese martial arts (koryu bugei) centered around the study of the sword:

  • Tenshinsho-den Katori Shinto-ryu at Capital Aikikai, from 2005 to 2015. I received a mokuroku license in 2008 under Sugawara Budo.
  • Kashima-shinden Jiki Shinkage-ryu at the Hobyokan, from 2008 to 2016. I received a Hobyokan chuden menjo from David Hall in 2018.
  • Owari Yagyu Shinkage-ryu first in 1994 in Port Washington, NY under Kato Kazuo, a visiting member of the Yagyukai, and then from 2014-2018 with my Hobyokan sponsor and colleague, Michael Heiler.


Katori Shinto-ryu Omote no Tachi

As time progresses, and life commitments grow, I put more emphasis on deepening my understanding of Shinkage-ryu kenjutsu. I continued to practice a subset of the Katori Shintō-ryu kata I know as a personal misogi (purification) and shugyo (asceticism), but due to this shift in focus, and also time and distance constraints, I no longer am a member of Capital Katori or Sugawara Budo.

I do maintain a practice of a subset of the TSKSR kata I learned, but modified to be more compatible with the principles and body mechanics I have cultivated in Shinkage-ryu. I call this activity Gassan-ryu in honor of the place (Gassan Dai Jinja) where I changed my path from modern jujutsu/goshin-jutsu to classical and traditional martial arts. That is a solo practice, and not something I generally share with others. There are excellent resources for learning TSKSR in the United States at this time, and I recommend interested parties seek out licensed instructors.

In 2016, I moved to Seattle and began to teach a small group portions of the Jiki Shinkage-ryu in order to maintain my practice of that art. Because my perspective is somewhat unique, having trained in more than one koryu and maintained a practice focused on developing an understanding of internal martial arts principles, I use the name Gassankan Heiho (月山館 兵法 ) to describe my Japanese swordsmanship practice as a whole. Simply, it is a name for the swordsmanship practiced at my school, the Gassankan.
