Famous judoka Yokoyama Sakujirō was known by the nickname Tengu, and his tokui-waza was hence named tengu-nage:
Yokoyama's specialty was tengu-nage ("mountain-devil throw"), said to be nearly on a par with Saigo's yama-arashi. It is not certain exactly what tengu-nage entailed. The name of the technique may be partly ascribed to Yokoyama's other nickname, "Tengu." Once, Yokoyama was traveling in the rural Hakone area. He met up with some rowdy porters and a fight ensued. Yokoyama thrashed them all so badly that they said to him, "What are you, some kind of tengu?" Yokoyama replied, "Yes, and I will be back if you don't behave yourselves!"
What throw was this? Was it a novel throw he devised/adapted, or was it just a synonym for an existing throw he favoured?
