I would say yes. Japan releases usually have at least 2 version of the single/album release. One is CD only, and the other usually includes the DVD with the MV and the Making Of, and additional performances. A good marketing technique is to have a bonus song(s) to make an exclusive 3rd version of the release. Then you can have an exclusive 4th version with a photobook and poster. Then you can have solo member covers to milk more money (Thank You Summer Love).
Those are some ideas how Japan-industry having such high sales and why so many people want to go to Japan to have releases cause they simply just make money from physical releases.
