Anime music, image song and Vocaloid

During the late 2000s and the early 2010s, the anime music industry, such as voice actors and image songs, added weight to Japanese music. Though anime music was formerly influenced by J-pop and visual kei music, Japanese indie music apparently influenced the genre at the 2006 FanimeCon. In 2007, after sampling voice actress Saki Fujita 's voice to develop it, Vocaloid Hatsune Miku was released, and many songs featuring Hatsune Miku were shown on the Nico Nico Douga. Some of the musicians featuring Hatsune Miku, such as Livetune and Supercell, joined large record companies in Japan. Livetune released Re: Package on Victor Entertainment on August 27, 2008, and Supercell released Supercell on Sony Music on March 4, 2009. The albums Re: Package and Supercell were not brought under the control of the copyright system of the Japanese Society for Rights of Authors, Composers and Publishers (JASRAC), breaking the tradition that the musicians under the major labels affiliated with the system.

In June 2009, voice actress Nana Mizuki 's album Ultimate Diamond became the first voice actor album to reach number one on the Oricon weekly charts. The fictional all female band Hōka-go Tea Time, from the anime series K-On!, released the mini-album Hōka-go Tea Time on July 22, 2009. The mini-album debuted at number one on the Oricon weekly album charts, becoming the first album by anime characters to reach number one. In May 2010, Exit Tunes Presents Vocalogenesis feat. Hatsune Miku became the first album featuring Vocaloids to reach number one on the Oricon weekly charts, replacing Hideaki Tokunaga's Vocalist 4, which had topped the charts for four consecutive weeks.
