Amazuppai Haru ni Sakura Saku

"Amazuppai Haru ni Sakura Saku" (甘酸っぱい春にサクラサク) is the first single by Berryz Kobo × Cute (pronounced Berikyū), a collaboration unit between the Japanese idol groups Berryz Kobo and Cute. The single was released on November 9, 2011.

It is a middle school graduation song.

Background
Different versions of the single were released simultaneously on two record labels: Berryz Kobo's version was published by Piccolo Town, which is the Berryz Kobo's label, while Cute's version was published by the C-ute's label, Zetima. There were 3 editions of each version: Regular Edition (CD only), Limited Edition A (CD+DVD), Limited Edition B (CD only).

There was also a so-called Event V, a DVD containing several versions of the music video for the song "Amazuppai Haru ni Sakura Saku", released.

The title song was appointed as the ending theme for Ōsama Game, a BS-TBS horror movie in which members of both Berryz Kobo and Cute played.

It is a graduation song, but, as Maimi Yajima pointed out, it's not a sad farewell song, but rather a positive journey song.

First "Amazuppai Haru ni Sakura Saku" will be included in the Hello! Project compilation album Petit Best 12 and later in the Cute's upcoming 2012 album Dai Nana Shō 'Utsukushikutte Gomen ne'. It will also be present on the Berryz Kobo's upcoming album Ai no Album 8.

Critical reception
Hotexpress's Tetsuo Hiraga wrote in his review: "The song has a consistent utterly happy and cute typical idol groove". But the reviewer also added that the song seemed very "chaotic" to him.
