I'm not familair with the bands you mentioned, but i assume it's hardcore punk and not hardcore house.
There is certainly a lot of Japanese hardcore around.
Try listening to Melt Banana, Guitarwolf and The Slutbanks for starters. There are lots more Japanese bands like these, but it's not the genre i listen very often, so i'd have to do some digging to get more bandnames.
It's also not my genre, so I don't know too much about Japanese hard rock as well. Living out of Japan also means that I have lost touch with the 'scene'.
This site is run by Dirk GΓ³mez from Germany. I've exchanged some music with him in the past.
His site is dedicated to Japcore, so you should be able to find everything you want to know right there.
Try utsu-p too, super hardcore, lynch, mejibray, dimlim, jiluka, KILLANETH, insanity injection by brn is a really good one, forbidden by despairs Ray... And of course nothing's complete without dir en Grey... Also checkout madman's espΓrit...
Acid black cherry, NoGod, Sadie, NOCTURNAL BLOODLUST OMG U HAVE TO LISTEN TO THEM AHH, mucc, human gas, kuro, the clay, gauze, moi dix mois, has some hard ones... GULU GULU OMG LISTEN TO THEMMM
Long story short there's a lot but they are hidden under a different genre, but they make hardcore music, and it's called vkei
PS. The gazette is pretty mainstream but listen to deux, falling, and ugly by them. Another good one band is disreign.
