Tsunku

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 typically 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, the latter in particular often being 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, as well as male fans who are not wota, both of whom are usually in their twenties and thirties, and occasionally older. Some of his works in the late 2000s were particularly mature and hard-hitting (considering the ages of the girls singing them), such as the Morning Musume singles "Kanashimi Twilight, "Onna ni Sachi Are" and "Resonant Blue". Although his own work as a soloist and in Sharam Q tends to lean towards pop-rock, he is best known for working with various arrangers to create highly melodic, richly-textured sequencer-driven electronic dance music which often features synthesizers, as well as guitar riffs and solos which sometimes hint at hard rock or heavy metal influences (such as in Morning Musume's "Ambitious! Yashinteki de Ii Jan" and Cute'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 small parts of lines in succession, building up to a chorus in which most (if not all) members sing in unison rather than using vocal harmonies; any harmonies that are present in the songs are often sung by other people (including Tsunku himself, who records his backing vocals so as to appear to sing "along with" the girls on their studio recordings during key parts of songs such as during choruses and on certain phrases, in a voice an octave lower than theirs). 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 backing vocals were sung by the group's members themselves. Furthermore, in the past few years, it has become even more common for members of Hello! Project's groups to provide the backing vocals for their songs themselves.

Recent years have also seen Hello! Project moving in a new direction musically, with prominent elements of dubstep and electro being incorporated into much of their recorded output, resulting in songs which seem at times to be almost experimental in style, at least by idol music standards.

Tsunku is also involved in Nice Girl Project! (NICE GIRL プロジェクト!).

As a result of the Japanese earthquake in 2011, Tsunku wrote a song titled Love is Here ~Kibou no Hikari~, dedicated to the victims. Tsunku is one of the many Japanese celebrities who have stepped up to support the victims and their loved ones.[15]

In March 2014, Tsunku announced on his blog that he had laryngeal cancer, which he found out after having throat surgery due to an unspecified condition. He also stated that he has been seeking treatment for it.[16][17] On April 4, 2015, Tsunku revealed that he had his vocal cords removed as part of his cancer treatment.[18]

In his memoir, Dakara, Ikiru, which was published in September 2015, it was revealed that he stepped down as Hello! Project's General Manager sometime after Morning Musume's New York concert that happened on October 5, 2014.[19] He still remains involved with Morning Musume as its Sound Producer.[20]

On May 4, 2020, Tsunku was among the 121 members of Up-Front Group to participate in a YouTube telework to support the frontline workers during the COVID-19 pandemic.[21][22][23]
