Trivia
A lorry featuring large images of the CD covers and a multi-screen video of the PV was used to promote the single.
As of 5 March 2012, Watanabe Mayu has performed Synchro Tokimeki (シンクロときめき) five times on TV. The first being the 120218 broadcast of Music Fair (fully live with a full live band), then the 120226 Girls Factory broadcast (recorded 120204, with live singing and a different live arrangement of the song), and then on the 120226 broadcast of Music Japan and 120305 broadcast of Hey!Hey!Hey! Music Champ (again with live singing), in which Mayu meets a real life alpaca in the studio. The fifth time featured live vocals and was on the 120328 episode of AKBingo!
On the release date, Watanabe Mayu had an internet livestream, consisting of interviews, footage from the Sony Records offices, and performances of both Synchro Tokimeki, and Mayuyuroid (which was the winner of fans votes for which b-side they wanted to hear).
On the first week of release, Synchro Tokimeki placed second in the Oricon Weekly Charts, selling only 2,938 copies short of the first place single.
It took Synchro Tokimeki six weeks to sell over 150,000 copies on the Oricon charts.
The coupling song "Mitsuami no Kimi e" was performed live on the 120318 broadcast of Girls Factory, in an alternative arrangement.
Mayu performed three mini-lives for Synchro Tokimeki, tickets of which could be won via a card in the CD single.
