Japan isn't weak in software if my game library has anything to say about it. ;-)

Fascinating that Joy-Cons run a TRON-compliant OS.

Docomo was certainly ahead with i-mode, but as the video notes i-mode wasn't successful abroad, and it was eclipsed by iPhone/iOS and Android, much as other mobile platforms (Palm, Blackberry...) were (though it will continue to operate until 2026.)

Line (perhaps similarly to WeChat) also pioneered the super-app space, but it was mainly domestically focused.

Incidentally it was SoftBank Mobile (formerly Vodafone Japan), rather than Docomo or KDDI, that adopted the iPhone in 2008, as an exclusive until 2011. That probably turned out to be a good move (though maybe not as good as investing in Alibaba.)
