If you want to see popular music concerts in Japan, coming in fall is a great time. Many universities have something like their school festivals around this time, and they often have fairly big name (Japanese) acts playing at the schools. Some singers hit five or more schools and the tickets are pretty cheap, and because some of the schools are pretty small, you can get rather close to the band. We went to see a triple bill of Dohzi-T (童子-T), BENI and YU-A at Rissho University in Saitama. They played for only an hour and a half, and each singer got maybe four or five songs. It was inside the school auditorium, so it was not very fancy, but because there were barely 500 people there, you could be very close to the action! There was only a single DJ and then the singers; no other live musicians or anything.
Unfortunately no pictures of the bands, but I think it is a great (and slightly different) way to experience the bands in Japan. Check the artist websites for links. To buy the tickets for this specific concert, I had to email someone at the University who was organizing the tickets, and then pay at a bank by bank transfer (振込み). If you don’t have your own bank account at a Japanese bank, you have to go to a branch of the bank used by the University to pay. E.g. the destination account was with Resona bank, so I had to go to a Resona bank branch to pay.
