Is Scheherazade an Isao Tomita track?

This discussion popped up recently on facebook about the track Scheherazade (Sheherazade) by Isao Tomita.

It is included on the Pictures at the Exhibition ultimate edition album – which contains 2 additional tracks compared to the original album. But very little is known about this track. You can find info on the internet saying that this track was recorded in 1983. Listen here (but note that this recording is in Japanese..)

There are rumours that this track is not an Isao Tomita track, but it sounds like it is.

Who of you knows more, share your knowledge or thoughts with us please.

Listen to Scheherazade on Letsloop or at spotify.
