I have made a few one off lessons for people interested in learning some koryū iaijutsu (classical Japanese swordsmanship) online there are two lesson videos available from Keishi-ryū. One chosen from Asayama Ichiden ryū 浅山一伝流 is available for free. Another selection is available from Shindō Munen ryū 神道無念流 as VOD.

You can find the lessons here. https://vimeo.com/ondemand/shinkanryu/
