A RAV4 in Europe is just a "SUV" (and one on the larger side). In the US, it's a "compact SUV"...

I'd largely question the accuracy of point 1 IN PRACTICE. Japan is notorious for uncounted and unpaid overtime, vacation days no one takes, and paternal leave you'd better not think of if you don't want to instantly become your division's outcast. I worked in a host of countries, including the UK and Japan (the latter about a decade ago - I'd be surprised if things had diametrally changed since that time). The actual work hours are not remotely comparable. (In fact the UK is one of the locales where I worked the least in terms of actual hours. Much less than in France, where they're supposed to be slackers... So generally I call BS on these stats.)

Acura is a brand made for North America. Just as in Japan, what you know as Acuras is sold in Europe as Hondas.

Polish-born person living abroad here. There definitely ARE "mind viruses" in the polish psyche, and pretty nasty ones at that. You might not have noticed them because they are from a different nature than the ones that infected Wester Europe and North American. For example, Poles by and large harbor an inferiority complex due to the decades of oppression and suppresson that makes them sell themselves short and act as people-pleasers to western nations and western firms (that's precisely what makes us so liked by those firms! and that's also your "looking to America" here). Poles as a nation are driven by romantism, not pragmatism, and that is the reason why we always get screwed on the world stage one way or another and have the reputation of being "dumb". I am as happy as the next guy to see economic development, but our mental maps let us down regularly, and I am not particularly optimistic for a change on that front.

Why would they want to bear the burden of an "hostile environment" (as the UK Home Office named their policy towards foreigners) AND declining economic prospects due to an economic suicide they had no say in?

The distance between a personal project or MVP and a legit commercial product is VASTLY undersestimated by non technical people.

Senior SWE / consultant working remotely since 2020 here. Besides all the "control" aspects, the truth is there's been a lot of abuse - a lot of it coming from certain locales. Here in Europe remote roles still exist to a certain extent (though they are a lot more scarce), but it's not uncommon now to see restrictions such as "remote from the EU", "remote from the UK", etc. To sum up: a certain faction has broken the trust of their employer/client, and blown it for everybody else.

One of the companies most disrupted by AI? Sorry, but that is nonsense. I have been using their products proferssionally for over 20 years, and still do to the same extent as ever. That's while being fully on the Agentic Coding bandwagon. Admittedly their attempts at integrating AI have been an abject failure, but who cares? My setup is Claude or OpenCode on one screen, Jetbrains (IDE mostly), both viewing and working on the same codebase, and that works great for me.

It's totally a thing in HK. Indonesia or the Philippines is where the maids come from.

Could you elaborate a bit on your tools / workflow? thanks

Bummer it is iOS only (?). Any plans for an Android port?

European freelance SWE here. I worked in Japan in your field for a number of years in the past decade. Your idea is utterly crazy. You are making 170K EUR in a low cost european locale=you are in a great position, especially in the current market conditions. Japan is like no.26 on the list of best-paying countries for IT skills. Meaning: Japan does NOT pay. Your expectations are simply unrealistic (and let's not get started on the value of JPY, which is at its lowest in decades), and you will need to be prepeared to take a MASSIVE pay cut. The fact that you are considering moving there with your family without doing the necessary due diligence is worrying, as it adds a whole extra layer of complexity that is not to be underestimated. Japan is welcoming to visitors. It is NOT welcoming to foreigners who come to stay. Japanese companies are also something else, and if you don't have experience with them, I would certainly not jump head-first. In short: as others have said, if you are interested in the "cultural aspects", travel there, do your freelance work remotely from there, but for the love of all that is good, don't move there with your wife and kids BEFORE you have tested out the waters exentisively. You will thank me later.

Software engineer with 20+ years of industry experience, mostly focused on the backend, with a specialization on fintech / capital markets / derivatives technology and distributed systems. I have worked for some of the top investment banks and trading systems vendors in Europe and Asia, handling duties ranging from architecture, design, project management, to delivery and ops.

Lately I have been successfully working with start-ups in the US (references available on request) and am interested in expanding my collaboration with this type of client globally.

I offer impartial, state-of-the-art software / solution architecture / audit services for your existing or planned systems, and can be as hands-on as you need me to be. I have a no-nonsense, less-is-more approach, have enough battle scars not to chase hypes or over-engineer, and am interested in building systems that run like clockwork long after I'm gone.

My working style is decidedly collaborative and friendly, but you can count on me to take the lead, stay on topic, present the trade-offs in clear language when a call needs to be made, and deliver on time and on budget.

Do you have an ongoing or planned project that you could use assistance with?
