Here's one I frequented semi-regularly when I lived in Tokyo. It is also maybe one of the most iconic game centers, being in Akihabara right outside the metro station with a large "SEGA" sign. Super not sketchy, mostly normal and mostly young people, no smokers, several women, even people there as couples.

I really think the OP was actually describing what in English we would call casinos (pachinkos) rather than arcades (game centers).

No I didn't. I was talking about Game Centers. I guess you're a too far gone Otaku to even tell how creepy the places you think of as "iconic" are.

The whole entertainment sector in Japan that caters to nerds aka otakus is very much not enticing to normal people. It's very seedy, and run by crime syndicates.

So you think Sony (biggest content holder for otaku market) is run by crime syndicates? Stop posting falsehoods without source.

Sony is a tech / electronics company. Stop letting your love for Japan getting the better of you.

Now Aniplex makes $$ https://en.wikipedia.org/wiki/Aniplex. They also acquired crunchyroll and funimation.

I accept any evidence that indicates other big entertainment company is run by crime syndicates. I just hope you stop posting falsehoods.
