It is called 'Golden Kite' because of a legend that, during Emperor Jimmu's eastern expedition, a bright, shimmering golden-colored kite landed on the nock of Emperor Jimmu's bow, which threw the army of Nagasunehiko into confusion.
「金鵄」という名前の由来は、神武天皇の神武東征の際に神武天皇の弓(武器)の弭にとまった黄金色のトビ（鵄）が光り輝き、ナガスネヒコの軍を迷眩せしめたという日本神話の伝説に基づく。
