If you could recommend some local bands, that would be so great.
I put some bands i like, with their sns if you want to check their sound/upcoming shows.
Note that I love mostly death and black.
Apologist is solid, traditional black metal. Very enjoyable, and funnily offensive MC from the singer.

Zardost is more on the death metal side, it's brutal and good.

Hernia44 is enjoyable to watch too, and costumes/custom instruments are worth seeing

Strange is death/trash (and rare enough to be mentioned, they have a foreign member)

I can't leave Yamada san out of the list, because he's God and his voice is the most beautiful thing in the world. He has 3 bands but the greatest one is
Dark Insanity (black metal)
Their next lives are 5th of July, 6th of May, 16th of September. If you're in Tokyo during one of those dates you must go and worship God. Seriously, although it's good YouTube doesn't do justice to his talent, he sounds one million times better live.
Note that all these bands are not big acts, so they don't do one-man shows.
But then tickets are cheap (usually around 2000y) and sometimes you go for a certain band and you end up discovering other great bands.
Also, it's not really a live show, but in September there will be the next occurence of the event i talked about
here (and it seems some automated bot replaced the name of the body suspension team "The H*****s" with the word "Escorts"
). Most of the DJs were playing metal, and the two bands playing that night were great. It will soon be 5 years that i'm here, and i think it was the best event i've been to since i arrived.
By the way, one of the bands playing was Antifeminism, and if they have a live while you're in japan, give it a try. Not only is the music brutal, but the frontman is a beast: for the finale, he put his arms on fire before diving on a pile of neon tubes (and it was real stuff, me and other people who were close got tiny shards of glass stuck in their legs
)
