Do you happen to know why Yojiro cried at the end of "Breath"?
Eeehhh… I think it was a combination of a few things, really.
First, he was playing on a piano that had been destroyed in the Sendai earthquake/tsunami disaster. That sort of connection to a terrible event, in such a small country, where the catastrophe of an area is felt more widely than it would be, say, here in the States, can make anyone feel upset.
Second, according to reports at the time, he and his girlfriend were on the verge of breaking up, if they weren’t broken up already. There had been some public fighting and rumors that she was cheating, which seem to be verified by witnesses seeing these things in public. They don’t seem to be together now, though whether or not he’s with anyone else, I don’t know.
And third, the lyrics of the song itself are pretty powerful and full of love, but they were written at a very different time in his life, so they might have been reminding him of some things.
My personal opinion is that all of these things sort of crashed on him all at one time, and he just couldn’t keep it together. The other members look like they were caught pretty off-guard by it, and they’re doing they’re best not to call attention to it or look at him and just let it pass. Noda himself is pretty embarrassed by the whole thing, and he keeps telling the audience that he’s okay and it’s fine, though it’s clearly not. I think he just didn’t expect it to come on him like that.
And I lose my shit every time I see it, because when Noda cries, I cry. It’s a law of the universe. I don’t even question it.
I can’t ever really know for sure what it was, but this is my guess. I hope this rambling helps. :-/
