Sagmeister VS. Gan Hosoya

I was doing research for my History of Graphic Design in Japan Since WW2 when I came across this artist named Gan Hosoya and I couldn't help thinking that his poster designed in the mid 60s looked a lot like Sagmeister's website. I know that Sagmeister has done work in Japan and who knows maybe Gan Hosoya influenced him. Just a guess, but you never know...
