Moon Mountain Hall [ 山月館; Yuèshān-guan ] is a training activity near Seattle led by Mark Raugas that is focused on the development of skill at traditional internal martial arts.

I practice Northern Wú Taijiquan [ 吳氏太極拳 ], Yin Baguazhang [ 尹派八卦掌 ] and Hebei Xingyiquan [ 冀形意拳 ] as taught in lineages preserved as part of Yin Cheng Gong Fa North America.

I maintain a practice of Japanese sword methods I learned at the Hōbyōkan [ 宝瓶館 ] as informed by my continued study of internal martial arts.

I mentor a small group of students in Seattle on traditional sword methods drawn from the Kashima Shinden Jiki Shinkage-ryū Heihō [ 鹿島神傳直心影流 兵法 ] of Namiki Yasushi and Itō Masayuki. We emphasize foundational methods, analysis of kata, and pressure testing in free practice.
