There wouldn't be much of a reason to have new albums on vinyl. Besides collecting and having the nice big artwork and just the fun of playing a record.
All the music is created digitally now and putting it on an analog format like vinyl wouldn't be best for sound quality.
But I still want Ayu on vinyl to add to the collection.
I think they would only start doing it regularly if vinyl sales start rising like in the west. I'm not sure how interested Japan is in vinyl.
