It's all Love! is a collaboration single between Japanese sisters Koda Kumi and misono. It charted No. 1 on the Oricon Singles Charts charts, becoming Kumi's third consecutive number-one single (seventh overall) and misono's first number-one single. It remained on the charts for eleven weeks.^[1]

It's all Love! became the first time a sibling collaborative effort charted since 1980's Dancing Sisters album by The Nolans.

The single had been long-awaited by Japanese fans, due to both Koda sisters being musicians under the same label, Avex, despite having differing musical styles.^[2] Kumi released music predominantly under the R&B and pop musical genres, while misono released music predominantly under the rock genre.^[3]

It was released as a standard CD, a CD+DVD combo and a limited edition fan club edition.^[4] 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. "faarway" was performed by Koda 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. misono had previously released the music video for "Tenbin ~Tsuyogari na Watashi x Yowagari na Kimi~" on her single Kyukon ~Yaruki•Genki•Sono Ki no Nekko~/?cm, although the song was not included on the CD.^[5]

Despite "It's all Love!" being a shared song, it was not placed on misono's corresponding album Me.^[6]

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

It's all Love! was released in three editions: a standard CD, a CD+DVD combo and a limited fan club edition. The CD for the standard and combination editions featured the title track, the coupling tracks "faraway" and "Tenbin ~Tsuyogari na Watashi x Yowagari na Kimi~", along with the corresponding instrumentals for each song.^[7] The DVD housed music videos for "It's all Love!" and "faraway", along with the behind-the-scenes making video of "faraway".^[8]
