There are two possible sources for the name of the avenue: "Yūrei" meaning ghost, due to the presence of numerous temples along the street, giving it a desolate atmosphere such that ghosts might appear and "Yūrei," an alternate reading for the given name of the first Minister of Education in Japan, and scholar Mori Arinori, who lived in the vicinity.
The avenue's name may originate from two possible sources: one is derived from the Japanese term "yūrei" meaning phantom or specter, which is inspired by the numerous temples lining the street, creating an eerie ambiance where spirits might be perceived. The other source is linked to Mori Arinori, a prominent figure in Japan's educational history and a scholar who resided nearby.
