Ai no Hi Mittsu Orange
Ai no Hi Mittsu Orange is a special collaboration song between solo artist Chara and Judy and Mary vocalist Yuki. The song was used in a Sapporo Beer commercial for their Fuyu Monogatari campaign.
The song was released as Chara's first single after her maternity leave for her second child, Himi, and while Yuki was taking a break from Judy and Mary activities.
The song's title is a pun: Ai no Hi Mittsu sounds like Ai no Himitsu.
The song debuted at #6 on Oricon charts and charted for seven weeks, eventually selling approximately 230,000 copies.
