Tadanori Yokoo is one of the world’s foremost graphic designers, considered to be in the same league as Milton Glaser and Seymour Chwast. He is also often compared to Andy Warhol and Peter Max.

Yukio Mishima said of him in 1968:

“Tadanori Yokoo’s works reveal all of the unbearable things which we Japanese have inside ourselves and they make people angry and frightened. He makes explosions with the frightening resemblance which lies between the vulgarity of billboards advertising variety shows during festivals at the shrine devoted to the war dead and the red containers of Coca Cola in American Pop Art, things which are in us but which we do not want to see.”

 

 
In the sixties, Yokoo made some amazing animated pop psychedelic shorts (with insane soundtracks), here’s “Kachi Kachi Yama” from 1965:
 

 
“Tokuten Eizou Anthology No. 1” (1964)
 

 
“Kiss, Kiss, Kiss” (1964)
