Tamiya kits, 4 back to back cabinet. All the cars, ships plane...everything freakin thing. I just only mention the kits only. For diecast, they have Autoart, Tamiya, Khosyo, Taiyo...etc...all this took up 6 back to back cabinet. They even have a limited edition of Aston Martin racing diecast cars.
BB guns, ranging from pistols to sniper to assualt rifle. Took up 3 double deck glass cabinet. PVC model kits....a whole section of it the size of your average Jusco toy section.
The toy section only, already took up 1 floor. You can go to Yurakcho, Tokyo or Yodabashi,Umeda for all this. All the place is accessible via subway so it's super convenient. There are still some smaller toy shop around Tokyo, If you want full range just go to the big department store to look for it.
