Sorry about not posting for such a long time. Any material on Kendokai and Nakamura sensei tends to be rare, so please understand.
Here's an updated Kendokai Karate official website. It looks quite dynamic, unlike the earlier version. It has a full screen video for the background, and a few video clips of dojo practice. I do hope that more material will be posted on this website in the future.
