Overview

Senha&Company (株式会社セーニャ, SENHA) is a Japanese music management company and record label. It was established by Koichi Inaba of Toy's Factory as a limited company, Yugen-gaisha Senha & Company, conceived as a minimal-unit operation combining management and a label under Inaba's own leadership. From its founding it was positioned as a label dedicated solely to the duo Yuzu, and Inaba has stated that he never thought of the label in terms of indie versus major. In July 2021 the company was reorganized into a stock company, Kabushiki-gaisha Senha. Its catalog numbers in the standard product-numbering system begin with the distributor code "SN". The company uses an illustration of a squirrel nibbling a CD as its symbol mark. As a label and management house, Senha&Company's roster has centered on Yuzu since 1997, along with Yuzu-related collaboration units such as Yuzu Oda (2006, with Kazumasa Oda), Yuzu Guren (2009, with Kimaguren), The fevers (2011, with TRICERATOPS), and MIZU (from 2020), an animated duo that streamed live on Yuzu's official YouTube channel. The company has also signed and later seen the departure of acts including NIRGILIS (2003–2004, later moving to Defstar Records), NICO Touches the Walls (2006–2007, later moving to Ki/oon Records), ocean (2000–2003), Snappers (2000–2003), and others. It has also been involved in soundtrack releases. Senha&Company operates within the Japanese music industry as a boutique label and management entity rather than a large corporate group. Its identity is closely tied to Yuzu's long-running career, and its releases are distributed through established Japanese music distribution channels; the Japanese Wikipedia article links it to VAP, Toy's Factory, and Sony Music Solutions, the latter being Toy's Factory's distributor. The company remains active, with its official website at senha.jp.

History

Senha&Company was founded by Koichi Inaba of Toy's Factory as a limited company, Yugen-gaisha Senha & Company. Inaba conceived it as a minimal-unit operation in which he himself served as leader, combining management and a label function. From the outset the label was positioned as dedicated solely to the duo Yuzu, and Inaba has stated that he never held any indie-versus-major mindset regarding the label. The company adopted an illustration of a squirrel nibbling a CD as its symbol mark. In July 2021 the organization was reorganized into a stock company, Kabushiki-gaisha Senha. Its catalog numbers in the standard product-numbering system begin with the distributor code "SN". Over the years the label's roster has centered on Yuzu (from 1997) and Yuzu-related collaboration units: Yuzu Oda (2006, with Kazumasa Oda), Yuzu Guren (2009, with Kimaguren), The fevers (2011, with TRICERATOPS), and MIZU (from 2020), an animated duo streamed live on Yuzu's official YouTube channel. The label has also been home to other acts at various times, including NIRGILIS (2003–2004, later moving to Defstar Records), NICO Touches the Walls (2006–2007, later moving to Ki/oon Records), ocean (2000–2003), Snappers (2000–2003), GO-BANG'S (2015), Hasegawa Kaori (2012), Uema Zen'ichiro (2005), and Yanagida Kumiko (2002–2007).
