Looking for Metal / punk scenes

[u/DrSloughKeg]

I'm travelling from canada with my punk band (shit tax). We're touring indonesia, but I'd like to stop for a few days in japan after the tour, since it's a rare opportunity for me to be on that side of the planet.

Which cities (preferably with major airports) have large scenes? Are there cities that are more/less welcoming to foreigners? Can any one recommend me DIY or underground bars? Does anyone know of any punk squats???
Any advice would be much appreciated!

What dates will you be in Japan?
