A friend of mine found a song that really sounds like JRPG music: Masayuki Sakamoto - Psy'chy

Does anyone happen to know more examples of such music? Preferably 80's or early 90's. I love this stuff :)

T-SQUARE 's whole discography is like that

I guess this album fits the description, at least that's the feeling I got when I first listened to it

Asturias - In Search of the Soul Trees

I feel like there's thousands of examples but these are the first that come to mind:
Joaquin Lievano - Gamelon Warrior

Asturias - Highland

Casiopea - Door of Truth

Yellowjackets - Wildlife

The Rippingtons - Destiny

Also this is cheating but:
Evan Marien - The One Who Bares Fangs At God (Xenogears)

I might have some more tight examples to what you want later if i think on it but hopefully these are good for now!

just wanted to thank y'all for sharing these tunes, i'm really enjoying listening to them

Thanks for the beautiful music pedipanol and Chimeratio. I really appreciate you took time to share these with us. Japanese prog like Asturias is something I need more in my life right now.

Chick Corea Electrik Band has some very JRPG-ish moments throughout its albums.
