Someone here will definitely know. The Hoshino musical instrument company owned Tama. The often produced lower line drum sets. There are too many to list, but they were all more or less the same. The only difference being the name on the badge. I've had a MIJ kit that I couldn't find any information on either. There are so many. If you look for Thunder Drums or Maxwin drums on google you'll probably notice they're a lot like your drums.
Thank you! I will check out the web sites...
