Hearts Grow

Hearts Grow was a Japanese pop/rock band. They were signed to Epic Records Japan in 2006.

Hearts Grow formed in 2004 after several music-lovers met in northern Okinawa at Ajisai Ongaku Mura, a practice studio near an Okinawan high school. They began performing street lives in Okinawa and soon after in 2005 released their first mini-album on the Ajisai label. They were later signed to Sony Music and in fall 2006 released their first major single on the label. Their single to follow, "Yura Yura", was used as the ninth opening theme to the anime Naruto.

They are known for performing the ninth opening of Naruto, the fourth ending of Demashita! Powerpuff Girls Z, the fourth opening of Gintama and the first opening of Tetsuwan Birdy: Decode.

In 2008, Yuuya had to leave the band for breaking his elbow. Takuya Kusunose, of the band Hysteric Blue, joined the band as a support member to replace him, but was not officially in the band.After the release of "Sora" later that year the band went on hiatus for reasons that were undisclosed. The reason behind it was thought to be due to such things as: disagreements in the group, as well as the death of Nakasone, who was the president of Ajisai Music (あじさい音楽).

However in November 2009, the band issued a statement proclaiming their hiatus. The reason for the hiatus was credited to musical differences between the band members. The statement also announced that the band's vocalist Haruna was currently working towards her debut as a solo artist.
