Just wanted to say I love reading these 
I was at the concert on 10 September too. That’s one thing I noticed too, way more foreigners/tourists (I mean i’m one of the foreigners too lol).
Funny that you said that about the merch thing when trying to talk in Japanese. I felt really bad, I came there for Forbidden but it rubbed me the wrong way when the lady switched to English so I spent more money on Damned instead
