This Disk Union also buys your cds. 
It is located on the basement floor of this building.
Besides J-Rock, J-Pop and other kinds of music cds, you can find many kinds of foreign heavy music ones as well.
My favorite Judas Priest dvd. I usually spend more than one hour in this shop.I love music more than anything else in the world. And my favorite music ranges from jazz to pop to heavy metal. If I'm going to buy a pop music cd, it is readily available at a local cd shop, but when I want to have a rare jazz cd or heavy metal cd, I have to drive for an hour to a cd shop that is in a neighboring prefecture.
The cd shop I visit to buy those cds is called "Disk Union", which has dozens of outlets mainly in the Kanto Region (it consists of six prefectures and Tokyo) .
It is true you can buy any cds on the Internet nowadays, but if you want to buy a rare secondhand cd cheaply without the mailing cost, the Disk Unions are the ones around Tokyo that satisfy your needs.
