@nprofile1q... yeah, I wondered about that, too. I don't know because it's been decades since I was last there 😯
Funnily enough, the original Tokyo Olympics was accused of plagiarism "The new emblem, created by Asao Tokolo, was introduced at the closing ceremony of the 2016 Summer Olympics in Rio de Janeiro, Brazil. Made by checkboards, it expresses a refined elegance and sophistication that exemplifies Japan. Previously, the original emblem, made by Kenjirō Sano, was scrapped after his design was found to have plagiarized the logo of Théâtre de Liège, a Belgian theatre company."
