Mitori Geiko (Jodo/Iaido)
In essence this website just contains a index of YouTube videos which I have tagged and timestamped with the kata that are shown, I have also added buttons to enable skipping to a given kata.

Usefull YouTube shortcuts:
While the video is paused, you can use the , and . keys to move a single frame back or forward.
You can use the arrow keys to jump back or forward by 5 seconds.
