Impressive that you went all the way out there with such limited Japanese ability and just randomly tried to make new friends in line.
I definitely hate when artists play in places way too small for the amount of people that would go. "Sold Out" seems to translate to "Fire Hazard" with the way people get crammed into those tiny venues sometimes.
Seeing how crazy and sweaty a lot of male wota get, having a female only section is always a good idea. It was 40℃ that day? Ouch!
