Well, I guess Japan has extra time to add English to all the signs for their 2021 Tokyo Olympics.
Japan is for Japanese culture, don't let other cultures take root in japan
...oh, and why are the Four Goddesses of Manga, CLAMP, known to be Anglophiles? The ultra-powerful wizard Clow Reed: half-English. Why did Ken Akamatsu have his main character in "Negima Magister Negi Magi" come from Wales?
And why can one only get from Japan the best replica of the gun used by Deckard: in "Blade Runner"...?!
Syd Mead, who created the look of that basis of Cyberpunk, also did the production designs - especially the eponymous mecha - of "Turn A Gundam": so there's your entire argument obliterated, OP.
