musoshinden iai, a japanese martial art, played by NAGAE Matasaburo (born 22 Mar 1910; 剣道範士七段、5 May 1996 居合道八段、died 20 May 1996 居合道範士), who is my grand father. This video was originally recorded circa 1969 in his late 50s or early 60s on monochromatic 8mm film with no sounds, then transferred to a VHS tape. I remastered it on a Windows 98 Pentium 2 PC in 2000.
