Now it's way behind the curve. PCs and accessories that I've not seen in UK/US stores for over a decade. Fax machines are still a thing and sold new.
But outside of such curiosities, it's interesting looking at where Japanese tech has sunk.
The Japanese can't bear to stock Samsung/LG televisions for reasons of national prime one presumes. So there are a bunch of locally branded televisions that seem antiquated - a far cry from the era where Sony held the crown for top end displays.
The PC vendors from Sony Vaio to Toshiba/Dynabook are gone or diminished. The consumer electronics/home electronics that once were interesting look increasingly dated given the Japanese obsession with putting lots of confusing buttons on their products instead of cleaning up the user experience (Japanese toilets are a great example of this... press the wrong button and get violated!)
And of course the camera section of BIC Camera is perhaps the most interesting predictor of where Japan's tech industry is headed. Sure the latest Canon, Nikon and Sony mirrorless cameras are amazing feats of engineering. The problem is that the cameras in phones have become so good that for 99% of the market, the camera in their phone is more than sufficient. So the Japanese camera vendors have become and will continue to will become increasingly niche. Of course the DJI drones next to the camera section offer capabilities the mirrorless variety can't match. So even more of the Japanese core tech industry will get eaten by China.
Pair all of the above with 260% debt to GDP (which is insanely insane even compared to the US/Europe), a population demographic pyramid showing not just an aging population but one that's rapidly declining and an economy that seems build on smoke and mirrors (go into any 7-Eleven and see unbelievably low prices for convenience groceries compared to any US/European store). Such businesses are part of what I'm told is an extensive network of zombie corporations that are run at a loss, subsidised by the banks in order for the banks to get aid/subsidies from the Japanese Government.
Then there's Toyota. Once a clear leader in both fossil fuel and hybrid cars that now has to issue press releases about future battery tech that isn't even close to production. They lag behind both Tesla and the European electric car vendors in actual offerings. Likewise Nissan's electric offerings look increasingly uncompetitive between their shenanigans getting their former non-Japanese CEO thrown in jail.
If these aren't enough - look around Japan outside of the 5 major cities. So much of the mid tier and smaller parts of Japan have been starved of cash. Cities built at the peak in the 80s and 90s with no signs of new development in 20-30 years.
My conclusion: Japan Inc. is a Ponzi scheme that Bernie Madoff would have loved to have conceived, veiled in superficial politeness intermingled with lots of courteous smiles and bows.
