The situation with western payment companies and JAV have been an issue for a while, furthermore the new laws that have come into effect with JAV where the films are made then they have to wait a few months before release where the performers have a "cooling off" period to decide if they want it released or not will cause a delay with normal jav releases as well as the already niche VR niches,
