The name Genba (玄蕃) came to exist by combining the characters '玄' and '蕃,' and '俵,' had a meaning of being able to thrust a bag of rice up with a spear, and '星' came from the name of the main character in Kanadehon Chushingura, Yuranosuke OBOSHI (大星由良助) (Kuranosuke OISHI being the model).
玄蕃の名は自らの「玄」と「蕃」の字の組み合わせ、「俵」は槍で米俵も突き上げるという意味、さらに「星」の字は仮名手本忠臣蔵の主人公大星由良助（大石内蔵助がモデル）の「星」の字。
