I always thought he wrote the lyrics alone.
Although, lately I read a interview he did on the
recent US Tour.He said he started learning English everyday with a teacher around the time he turned 28. Sorry I can't find it now but someone will know the one. If so this was around the time of Art of Life's release. Although who knows when he actually started writing the lyrics?
In another interview he said:
From
NY interview.

NT: How did you learn English?Y: When we came here, we did some kind of press conference and nobody spoke English. They said, how're you going to do this without speaking English. I said, I will learn...I said that in Japanese probably (laughs). So I just learned.
NT: How long did it take?Y: I would say three years. Before I went to the recording studio I did like three hours lesson six days a week.

I don't know if the 3 year gap he is talking about is from 1990 to 1993 [Pre-Jealousy and Art of Life album] or did he learn from 1993 to 1996.[Art of Life to Dahlia album.] It definitely was not around the time he wrote Vanishing Vision lyrics
Anyway even though Yoshiki said what drives him is he still hasn't made that perfect song. I think he pretty much got as close as you can get with Art of Life...
