"It's all Love!" is a collaboration single by Japanese singer-songwriters Koda Kumi and Koda Misono. The single was originally set to be released on March 4, 2009, but was pushed back to March 31.

It's all Love! is a collaboration single between Japanese sisters Kumi and misono. It charted #1 on the Oricon Weekly charts, becoming Kumi's third consecutive number-one single (seventh overall) and misono's first number-one single. It remained on the Oricon charts for eleven weeks. This was the first time since 1968 with siblings releasing a single together to chart.

The single had been long-awaited by Japanese fans, due to both Koda sisters being musicians under the same label, Avex, despite the sisters having differing musical styles. Kumi released music predominately under the R&B and pop musical genres, while misono released music predominately under the rock genre.

It was released in CD, CD+DVD and CD [FanClub Ed.]. At some local Tower Records stores, the single was paired with a poster as a first-come, first-served promotion.

Along with the sisters' collaboration song, there were two other songs on the single, each performed solo by each sister: faraway was performed by Kumi and Tenbin ~Tsuyogari na Watashi x Yowagari na Kimi~ (天秤~強がりな私×弱がりな君~ / Balance ~Strong Me x Weak You~) was performed by misono. However, only faraway contained a corresponding music video.

The single is certified Gold for shipment of 100,000 copies and It's all Love! is certified platinum for full-length cellphone downloads.

It's all Love! was released in three editions:

It's all Love! was used as the ending theme to Nippon TV's Sukkiri!! (スッキリ!! / Refreshed!!).
