As someone who's lived in Tokyo for 10 years it's largely met my expectations. My living situation is far more modern than the western country I'm from, even if my suburb looks a bit plain (my only real complaint is that there's too much concrete and not enough trees).
Would even go as far as to say many comments about the place being trapped in the 80s or 90s don't match reality. For instance, the only time I've ever been asked to use a fax machine was by a US company.
The decaying rural areas of Japan would probably love to be stuck in the 80s if they can. Too late, now they have hollowed out and everyone young is moving to the same cities most tourists stay at.
Every time you read a story about some Japanese town offering people, even foreigners, money to move there and occupy an abandoned house, keep in mind this is a gesture of desperation, not gratitude,
Decaying rural areas happen in every country, throughout history, throughout time. It’s just how the world works.
The only reason it recently reversed in the US was due to COVID.
Second, many countries are modern in some ways and backwards in some other way. To label a country as modern or not is silly.
Here how it works: I build a porch today and my neighbor builds a pool. In 30 years, he builds a porch but I build a pool. If you cherry pick porches, I look outdated and he looks modern, but it’s reversed if you cherry pick pools!
Japan has seen millennia of huge cultural shifts. Its strength is its ability to adapt and survive with some measure of continuity, even while embracing the new reality. Go watch some Ozu films. They're all about the "hollowing out" of traditional small-town lifestyle and culture. It isn't so much a problem as a feature of the landscape that reminds people about how transient their reality can be.
Additonally, most foreigners who would comment on HN or Reddit are earning significantly higher than the average Japanese or even Tokyoian.
The people you're probably thinking of are working in finance or Japanese mega venture/US tech companies. They make up a vanishingly small percent of foreigners working in Japan.
> finance
Most finance roles in Japan almost exclusively hire Japanese nationals
> Japanese mega venture/US tech companies
They don't tend to hire foreigners in most cases except for Chinese (Taiwanese and Mainland) and Koreans
