Wake Me Up is TWICE's 3rd Japanese maxi single, released May 16, 2018 through Warner Music Japan. It features 4 tracks — "Wake Me Up," "Pink Lemonade," and their respective instrumentals — and comes in four versions: Limited Edition A (CD+DVD), Limited Edition B (CD+DVD), a Regular Edition (CD only), and an exclusive ONCE JAPAN fanclub edition. The Limited and Regular editions each include 1 of 10 trading cards, and all three non-fanclub editions were also available together as a Warner Music Direct box set. The single broke records on release, topping the Oricon Singles Chart and becoming the first single by a foreign female artist to earn a Double Platinum certification from the RIAJ — making it one of the most commercially significant physical releases in TWICE's Japanese discography.
