Which shows? It really does depend, but I assume you are not talking about Yuzu's solo ones.Just curious. If someone lived in Japan and was retired, how much of a pita would it be to obtain good tickets to say the top 4 shows, ride the modern train system to near the events, get a hotel, and get to the events?
I live in a country where Spokane city buses have to be checked with bed bug sniffing dogs and the train system is archaic.
Some other shows also run a lottery, I understand from sm chatter but tickets may be available after that's finished as not all sell out in it.
