It reminds me of "hidari mae" - the wearing of the uwagi with the left side on top of the right, which, as you probably know, is only done once in your life, and that is the last time - unless you are a poor unsuspecting newbie from outside Yamato.
There is a story of a foreign woman being carried out of the Yoshinkan Hombu because she inadvertently had put on her uwagi hidari mae, but this is off-topic.
Ethan, I am in Yamato right now, training in a Yoshinkan dojo, and we are all wearing the left side on top of the right. Sorry. Best, Chris
