In the 1980s/90s, NoA was trying to promote a squeaky clean image to avoid scandals with low quality or NSFW licensed games, the Japanese computing market was full of computers incompatible with each other and computers literally anywhere else, and if you didn't know a guy all these foreign console games required Japanese language knowledge and weird mail order catalogs to obtain along with some region lock bypass device.
Nowadays there's emulators, every single Japanese game is written for the same OS and hardware the rest of the world uses (this is how Touhou and VNs got huge), and you can go on eBay even to buy a Sharp x68000 even if the prices are methed up. Also now Nintendo is the company that censors the least out of the 3 game console manufacturers.
