Subaru Shibutani

Shibutani entered Johnny & Associates in 1996 on his birthday, September 22 (along with future fellow Kanjani Eight member Ryūhei Maruyama) after passing an audition. He did not hear from the agency until December 1996, when he was called to a second audition for a KinKi Kids concert. It was there where he first met two other future fellow members You Yokoyama and Shingo Murakami.

Shibutani's ability to sing was acknowledged during the recording of an original Kansai Jr. song "Boys in the West Side", theme song for Kanjani Knights, a Kansai Jr. show that ran in 1998. He was a regular on the show together with Yokoyama and Murakami. The trio went on to appear on many Jr shows together, becoming close co-workers and dubbing themselves "3baka" ("the 3 idiots"). Together with Ryo Nishikido, they were dubbed the four top Kansai Jrs. This meant increased exposure, with opportunities to appear in many Jr shows in Tokyo as well. Shibutani's big break was an outstanding solo performance on Music Station which would see him move to live in Tokyo, followed shortly by Yokoyama and Murakami. At Tokyo, he received many singing jobs and the 3baka became a fixture in the Tokyo Jr TV programs; They went on to star in their own TV series, IkeIkeIkemen, and were regulars on Koichi Domoto's show Pikaichi.

Around 2000 to 2001, work offers from the agency diminished greatly for the Kansai Jrs. Out of work in Tokyo, they moved back to Osaka, and found part-time jobs to supplement their salaries.

In 2002, Johnny Kitagawa had the Kansai Jrs put on an old play previously performed by their seniors, SMAP and KinKi Kids, called Another. This marked a revival of Kansai Jr activities but Kitagawa's strategy this time was to localize the Kansai Jrs' activities and keep them based in Kansai. Shibutani returned to the stage. He also appeared on TV regularly, on J3Kansai.

In 2003, Johnny Kitagawa formed Kanjani Eight using the top Kansai Jrs. He decided to have Shibutani sing enka and debut Kanjani Eight with him as lead singer. In August 2004, the group released its first single, Naniwa Iroha Bushi, an enka song infused with rap. The single made it to No. 8 on the Oricon singles chart despite its Kansai-limited release. This was followed by a nationwide release the following month that shot Naniwa to the top of the chart. Shibutani and his fellow members learned about their official debut through the newspapers.

Kanjani Eight's songs encompass a wide range of styles besides enka and pop; rap, jazz, funk, rock-and-roll, blues, dance, ballad, and disco are among the other styles featured.

In addition, Shibutani is also the main vocalist for Kanjani Eight subgroups, SanKyoudai, an acoustic music group, and SubaruBand, a rock band. He also plays several instruments, the guitar, harmonica and shamisen.

As a Jr., Shibutani wrote several original songs in collaboration with the guitarist of Jr. band FIVE, Nakaegawa Rikiya, who composed the melodies. These songs were performed by Shibutani with FIVE. Subaru also collaborates with Kanjani8 band member, Shota Yasuda. The two write the songs for their band, SubaruBand (ONE, High Position, DownUp). He regularly writes the lyrics for his concert solos as well.
