yourness is a Japanese group that formed in September 2014. The project is credited to 古閑翔平, 黒川侑司, 小野貴寛, and 田中雄大, and the official website is yourness.jp.
Built around its recorded output rather than a heavily public-facing image, yourness is easy to identify through release credits and catalog listings. That makes the group a practical reference point when tracing songs, artist credits, or official releases back to the lineup behind them.
