☵ Yin Cheng Gong Fa North America (YCGF). The website of Zhang Yun, lineal disciple of the late Grandmaster Wang Peisheng, who resides in Pittsburgh, PA. Zhang Yun and his senior students are an excellent source for instruction on the Chinese Martial Arts of Bagua Zhang, Taiji Quan, Xing Yi Quan, and Tongbei Quan.
☵ The Shinyokai. Toby Threadgill preserves and teaches Takamura-ha Shindo Yoshin-ryu, a late Edo-period style of jujutsu encompassing both armed and unarmed combat in a refreshingly integrated manner. Murakumo Dojo is led by Doug Walker, chuden menkyo in Takamura-ha Shindo Yoshin-ryu, near Atlanta. Yoshinkage Dojo of Washington, DC is led by Michael Heiler, shoden menkyo.
☵ The Yushinkan. The Yushinkan is a Daito-ryu Takumakai shibu (branch) in NYC which teaches a traditional form of aiki-jujutsu as passed down by students of Takuma Hisa, who trained under Takeda Sokaku and Ueshiba Morihei in Daito-ryu. It is a small and dedicated group worth investigating as a source of training in Daito-ryu if you are in the tri-state area. The Seattle Aiki Club is a Takumakai shibu dojo in Seattle led by Kenneth Freeman.
☵ The Ryuzukan: Daito-ryu Aikijujutsu. Chris Covington and Brian Wagner run a Daito-ryu Aikijujutsu dojo called the Ryuzukan under the permission of Kondo Katsuyuki, the current headmaster (soke) of mainline Daito-ryu. At annual kagami biraki of the Hobyokan, I have been very impressed by Chris and Brian's Daito-ryu demonstration -- their techniques were crisp, powerful, and balanced. The Daito-ryu I saw Chris and Brian perform have been some of the best jujutsu demonstrations I have witnessed. They also are strong practitioners of Jiki Shinkage-ryu. If you are interested in training in Daito-ryu in the Maryland or Virginia area, they are excellent resources.
☵ Lonin. The Lonin League is a collective focused on Historical European Martial Arts (HEMA) located in the Georgetown neighborhood of Seattle. Lonin has several activities ongoing, including a studies focused on the Italian sword methods of Fiore, German Longsword (Kunst des Fechtens or KdF), English backsword, and Victorian martial arts, known as antagonistics.
