Usagi is the Japanese word for rabbit.
So the character Yuzuha Usagi represents the rabbit.
This is a retelling of Lewis Carroll's "Alice in Wonderland" story, with the characters' names reflecting their role in the story (Ryohei Arisu is named after Alice, Yuzuha Usagi is the White Rabbit, etc).
Producers filmed the Shibuya crossing scenes 100 kilometers away in Ashikaga.
Haro Aso, who wrote and illustrated the manga, said he based the lead characters on himself. In the production notes released by Netflix, Aso was quoted saying 'I looked back on what I was like around age 20 and created Arisu based on my own lack of direction at the time'. Aso went on to share that the dauntless character of Usagi was based on his independent streak and ability to rely on himself instead of others.
Based on manga series "Imawa no Kuni no Arisu" by Haro Aso (published from 2010 to 2015 in magazine Shonen Sunday Super and published from 2015 to 2016 in magazine Weekly Shonen Sunday).
