Gassankan or Yuèshān-guǎn [ 月山館; "Moon Mountain Hall" ] is a training activity near Seattle led by Mark Raugas, focused on the development of skill at traditional internal martial arts and classical Japanese swordsmanship.

We currently offer two areas of study:

• Internal Martial Arts — Northern Wú [ 吳 ] style Taijiquan, Yin style Baguazhang, and Hebei Xingyi Quan.
• Japanese Swordsmanship — rooted in the historical kata of Jikishinkage-ryū and combined with free practice.

Please contact us for information on current training opportunities.

For essays and updates on training, culture, and the philosophy of the martial arts, please visit the Inner Dharma writing project. A collected set of works on Shinkage-ryū heihō is also available as a book:

• The Truth of the Calm Spirit: The practice of Shinkage-ryū Heihō as Taoist Internal Alchemy, 2025.
