Printed on back and on CD is: "Made in Japan", but this release has not the typical signs of a Japan distribution.
No sign of the copyright (JASRAC) on CD. No flag/Obi around the case. It is possible that this CD was distributed in South-Korea, although no "K.E.C.P.P." note is on CD.
Whatever... most possible this CD is illegal. Not all songs are covered by the copyright loophole.
