Record contains some gimmicks. Insert in some copies included the following message in Japanese “ Dear Customer, Thank you for purchasing the Y.M.O. MEGA MIX. This record is different from the original work due to special editing. There is a special sound (scratch sound) after the second song on the B side, "Behind the Mask," but please enjoy by putting the needle back on. Alpha Record Co., Ltd. Sales agency: Warner Pioneer Co., Ltd.”
Bottom "spine" of the outer sleeve contains the text: "Oh my god! You've found this word. You will see something beyond the line." --- Hiroshi, Gota & Doddie ---
Not noted on the sleeve, this record also contains an acapella vocoder only version of "Behind The Mask" after the remixed version of the track on side B. This is exclusive to this pressing.
Side B contains a second groove "hidden" AFTER the normal groove in what is normally the runout area near to the record label. This groove contains a small soundbite.
The megamix on side A is different to the CD version released in 1990.
