I agree this is not a Japan release, as the catalogue number fits CBS' Europe & Rest of World (excluding US & Canada) convention; Japanese releases tend to have completely different catalogue numbers to any other country, and the CBS label in Japan before 1991 was CBS/Sony, with this album receiving a release on that label in 1985, as seen here.
In the 80's it often happened that CD's were pressed in Japan for the rest of the world. The capacity in Europe, UK and USA at the time was small for the pressing manufacturers. If I am correct this version has "Printed In Holland" on the covers somewhere? If so, it was released in 1986.
I used to have it, lost it (stolen) and bought it later again.
