He is best known for having two major roles in the Japanese music landscape: first as the lead singer of the popular rock group Sharam Q, and now as the producer, primary composer, lyricist and main studio backing vocalist for idol supergroup Morning Musume, in addition to Aya Matsuura and other associated artists under the Hello! Project banner, for whom he has written and produced vast majority of their chart-topping hits. He has also produced music for other Japanese artists, including Ayumi Hamasaki's first number one single. His musical influences include The Beatles, Queen.
In June 2006, Tsunku married Kanako Idemitsu (出光 加奈子), a 25 year-old former model from Fukuoka. The couple have fraternal twins (one boy, one girl) born in 2008 and one daughter who was born in 2011.
Tsunku later worked with Nintendo and J.P.ROOM to create the music video game, Rhythm Tengoku. It was released for the Game Boy Advance on August 3, 2006, and later as an arcade on September 20, 2007. He also worked on Rhythm Heaven for the DS and Rhythm Heaven Fever for Wii.
On October 1, 2006, it was announced that Tsunku had created a new company called TNX consisting of singers such as Ami Tokito and other people including Tatsuya Naka, a magician who appeared on Hello! Morning.
On September 26, 2007, Tsunku released a compilation album with the temporary title of "Sharam Q ~ Morning Musume" ~Tsunku 15 Years in Entertainment Commemoration Album~, containing songs by both Sharam Q and Morning Musume, and another one on December 5, 2007 titled Tsunku Best Work Collection, containing songs sung by Tsunku himself.
Music composition and lyrical works 
Hello! Project 
Tsunku is responsible for majority of the musical composition and lyrics in Hello! Project, noticeably for Morning Musume where all of their singles have ranked in the Oricon Weekly Singles Top 5 (excluding "Morning Coffee" and "Mikan"). Arranging is normally left to outside parties with track records in arranging popular, anime and game music.
His works are mainly pop-oriented with catchy melodies and romantic, idealistic and sometimes even humorous lyrics which are pitched to appeal to a young audience. However, many of the female vocalists who perform his songs have a large, dedicated fan base composed of older male wota, mostly in their twenties and thirties. Some of his more recent works are dark, mature and hard-hitting, such as "Onna ni Sachi Are", "Kanashimi Twilight" and "Resonant Blue". Although he can create regular rock songs and even relatively simple acoustic pieces, he is best known for creating sequencer-driven music with characteristics such as layers of contrapuntal melody lines, melodic basslines, and extensive use of synthesizers, as well as guitar riffs and solos which sometimes show hard rock or heavy metal influences (such as in Morning Musume's "Ambitious! Yashinteki de Ii Jan" and C-ute's "Forever Love"). Typical vocal arrangements in the songs he writes for Hello! Project's groups tend to revolve around the members taking turns at singing lines and sometimes even short phrases in quick succession, building up to a chorus in which all or most members sing in unison rather than using vocal harmonies; any harmonies that are present in the songs are often sung by Tsunku himself, sometimes with the help of other backing singers, notably Atsuko Inaba. However there have been some exceptions, such as the Morning Musume songs "Morning Coffee", "Furusato", "Memory Seishun no Hikari", "Love Machine" and "I Wish", where most (if not all) of the harmonies were sung by the group's members themselves.
Nice Girl Project! 
Tsunku is also involved in Nice Girl Project! (NICE GIRL プロジェクト!).
2011 - Present 
As a result of the Japanese earthquake 2011, Tsunku has written a song titled "Love is here ~Kibou no Hikari~" dedicating to the victims. Tsunku is one of the many Japanese celebrities who have stepped up to support the victims and their loved ones.
