How often do you add noise to your search queries? What sort of noise to add (whether it's truly random or based on your subconscious) is another matter.
There are extensions which can do it for you. I don't bother, because I'm using ddg for search. One can whip up something similar for llm-s as well and I'm sure that soon someone will right one for chat gpt. This will avoid the subconscious bias.
One thing that I can comment on is that Japan has drastically changed its immigration policies and opened its doors to workers from overseas. A decade or so so ago you needed to have lived in the country for more than ten years to gain permanent residence, but now you can get it in as little as 3 years. English is much more common especially in major cities, partly thanks to the preparation for the Tokyo Olympics. Support for foreigners living there has increased likewise. But yes, still a long way to go until you see immigrants take on top roles in major corporations or even the government.
Incorrect: it's 1 year if you score 80 points on the point list for the HSP visa, and 3 years if you score 70 points.
As far as I can tell, Japan has the easiest and most permissive immigration policies among developed nations, bar none. Compare with the "pro-immigration" US where there's strict limits on worker visas, H1-B holders have to leave the country very quickly (a week?) if they lose their job and can't find a new sponsor fast, there's strict limits on green cards (PR) with a lottery of all things, etc.
I've switched to using PowerToys Run (in the Microsoft PowerToys apps family). It's good to have access to everything in one place (including open windows, settings, ..) and access them without touching the mouse, however the lag can sometimes get annoying. On the plus side it's open source and continuously improved.
As someone who used to live in Japan I can say that Chilean salmon is much more common than Norwegian while it is also cheaper. The higher price of the Norwegian salmon and its packaging which has the character for fresh used before it ( 生 - as opposed to cured with salt) is made to give the impression that it is superior. I don't have the data for this but I think Sushi sold in stores is mostly Chilean too, unless being explicitly tagged as Atlantic in which case again it would be more expensive.
It is often the same Norwegian salmon companies which own the Chilean farms too, but there they don't have to abide by Norway's environmental standards (and I'm pretty sure they lobby to discourage Chile from adopting similar restrictions)
