Originally it was used to imitate Kurama Tengu who was the most popular hero of historical drama especially among children, in which Kurama Tengu played by Kanjuro ARASHI was wearing Sojurozukin (the hood of Sojuro) as his trade mark, which was commonly called 'the hood of Kurama Tengu' or 'the squid food' due to the shape.
これは本来、時代劇ヒーローのなかでも特に子供に人気があった鞍馬天狗に扮するために、嵐寛寿郎演ずる鞍馬天狗のトレードマークであった宗十郎頭巾（「鞍馬天狗の頭巾」とか、形状から「イカ頭巾」などと俗称された）を真似るために用いられたものであった。
