They had their first concert at the Join Alive music festival on July 24, and their second at the Fuji Rock Festival on July 31.

Saito covered "Hells Bells" for the March 2008 AC/DC tribute album Thunder Tracks. He has made guest appearances with the rock band Lazy since 2008. He is a featured artist on the 2009 version of their 1980 song "Kanjite Knight" for the TV show Shin Mazinger Shōgeki! Z Hen!.

After 15 years in the music business, Saito's popularity exploded between 2007 and 2008. In 2007, his songs "Wedding Song" and "Ai ni Kite" were hits after being featured in popular TV commercials. The same thing happened with "Ya Mujō" and "Otsukare-sama no Kuni" the following year, with the former going on to win an Excellent Work Award at the 50th Japan Record Awards. Saito's March 2007 album Kurenai-ban is officially labelled a "concept album" because the songs are all about love. With few exceptions, it is mainly composed of covers of songs by other artists. His 12th studio album I Love Me was released in October 2007. The August 2008 compilation Utautai 15 Singles Best 1993–2007 reached fourth place on the Oricon Albums Chart. Music news websites reported that another reason for the late success was that celebrities, including some of which grew up listening to his music, were publicly praising Saito, such as Ryo Nishikido, Riko Narumi, Kazutoshi Sakurai and Puffy.

Saito has collaborated several times with author Kōtarō Isaka. Isaka quit his company job and focused on writing after hearing Saito's 1997 song "Kōfuku na Chōshoku Taikutsu na Yūshoku". The author wrote the 2007 short story "Eine Kleine" after receiving a request for song lyrics from Saito, and a character in it is named after the musician. Saito wrote the song "Very Very Strong -Eine Kleine-" based on the story, and Isaka then wrote a story titled "Light Heavy" in response that was included with the limited edition of the single. When Eine Kleine Nachtmusik, the Isaka collection that includes the two previously mentioned stories and others, was adapted into a film in 2019, Saito provided its music. Saito previously provided music to the film adaptations of Isaka's Fish Story, Golden Slumber and Potechi.

In 1992, Saito appeared on the TBS audition TV show Seiki Roku Wagayateki Denshi Miyake Yūji no Tenka Gomen!. He made his professional debut in August 1993 with the single "Boku no Mita Beatles wa TV no Naka" on BMG's Funhouse record label, and had his first one-man concert at Nissin Power Station on September 17. His first album, Aoi Sora no Shita..., followed on September 26, 1993. Saito's 1994 song "Aruite Kaerō" was used in the Fuji TV children's show Hirake! Ponkikki. His fourth album Fire Dog was released in February 1996. 15 years later, its song "Sora ni Hoshi ga Kirei" was chosen to be the theme of the 2009 film Kichijōji no Asahina-kun. Saito's first release to reach the top-ten on the Oricon music charts was his 1997 album Dilemma. His seventh album, March 2000's Cold Tube, was his first after switching record labels to Victor's Speedstar. In 2006, Saito and other musicians born in 1966 performed under the name Roots66 for an event put together by FM802.

Kazuyoshi Saito (Japanese: 斉藤和義, Hepburn: Saitō Kazuyoshi, born on June 22, 1966 in Mibu, Tochigi) is a Japanese singer-songwriter.
