Funny enough, I didn’t write Raising Your Hands for 万歳 and I was wondering about it when I saw it as part of the meaning.
Well, this morning I started playing Ring Fit adventure again, and while it was kana, nevertheless, hearing the instruction while exercising was pretty awesome. Wouldn’t understand it without going through that list of exceptions I’ve made.
