>Eating out. At many Japanese restaurants, you have a tablet computer at your table, or you get a QR code to order on your phone. You use the tablet/web app (which admittedly doesn't always have the greatest UI, esp when you switch to English) to order your food and maybe pay.
That experience is horrible, and not just because pecking at a small screen for ants is horrible. Quite often the thing flat out doesn't work and/or is laid out in the most incomprehensible way possible that it's just faster to call a waiter over.
Also, owing to this being computer hardware sitting right next to food, the things are almost always grimey. Proper menus at least are ostensibly cleaned between customers. This isn't a problem specific to Japan, though.
>Toilets: they all have electronic controls to spray your butt after you poop. You can select water pressure, activate seat heating, etc.
Yeah, they have that since at least the 90s or something. Nothing new. I appreciate the engineering that goes into them, but it's a case of Galapagos.
>Public transit fare cards: in Japan, virtually every public transit system uses "IC cards" based on the Felica NFC chip.
They're great, but the world is starting to move ahead of them with everything moving to smartphone NFC and in a way that is carrier and brand and network agnostic.
>Remote-control air-conditioners.
They're great, particularly with how quiet they are. If it wasn't obvious from the toilets, Japan is great at hardware engineering. The problem is this doesn't translate to software engineering and high tech in general.
>Interpersonal messaging. In Japan, everyone uses LINE.
LINE is a perfect example of Japan's irrelevancy in software. Why? Because LINE is a South Korean product.
>Bullet trains. Japan leads the world,
Yup, top notch engineering as mentioned. Bad news for the maglev since that's being held up in political power struggles, though.
>Combination washer/dryers.
They've become such a mundane commodity thanks in no small part to South Korean and Chinese mass manufacturing that Japan is hardly relevant there anymore.
>Chip manufacturing. The US only has Intel,
The US also has Micron and Global Foundries, along with old school guys like Texas Instruments and more. Though I agree it's mostly Intel (and Micron) pushing the envelope.
Japan has a very bad track record with chip fabrication ever since they lost sight of everything, Elpida and Toshiba by far being the most tragic examples. The jury is indeed still out on Rapidus, TSMC expansion, etc., but I'm personally not holding my breath.
