The name is a combination of the two members' family names, Kobuchi Kentarō (小渕健太郎) - guitar, vocals - and Kuroda Shunsuke (黒田俊介) - main vocals - respectively shown in the pictures below.
In May 1998, Kobuchi and Kuroda met each other in Sakai, near Osaka. Kobuchi was a salesman who held street concerts every Saturday for relaxation and Kuroda was a physical education teacher and a street musician. In September the same year, Kobuchi offered Kuroda a song and seeing that Kuroda was not a skilled guitar player, Kobuchi became the guitar player of the group. Thus, Kobukuro was formed.
Kobukuro signed with Warner Music Japan in 2001, and made their debut with the hit single, "Yell" which reached number 4 on the Oricon Charts.
Kobukuro released the studio album Nameless World on December 21, 2005. Nameless World became their first number-one album on the Oricon weekly charts. On September 27, 2006, they released their greatest hits album All Singles Best, which topped the Oricon weekly charts for four consecutive weeks.
More recently they have released their greatest hits album "All Singles Best 2", as well as the single "One Song From Two Hearts".
Below are some of there songs. Enjoy!
