Jordan for example has the same population size as Sweden, that's about where the similarities end.

Sweden, along with Canada and Australia, are just about ideal micro US versions in technology, in terms of potential to pull off your scaling of activity. Good market economies, relatively robust technology societies and technology economies, high GDP per capita and incomes, plenty of wealth and capital to invest, stable open societies with respect for human rights, english language use giving them global benefits (Sweden having one of the world's highest english language adoption rates, outside of primarily english speaking countries), and so on.

Japan has far less spending power per capita - disposable income - than the US, and their economic output per capita is similarly far lower. Their cost of living is not far lower to offset. US GDP per capita will be around $63,000 for 2018. Japan is down around $38,000 to $40,000. Culturally Japan has historically not been friendly to risk taking, entrepreneurial activity. That has shifted some over the last 10-15 years, but not immensely (it's starting from an extreme where a long corporate career was the only acceptable path). There's a considerable difference between Sweden and Japan on that conservativism. Japan also is very different at a macro level, they put themselves into a particularly bad 20+ year debt trap that has robbed their economy of the surplus capital it needs to invest into expansion and innovation.

Germany is doing OK, in regards to technology and tech start-ups. They've lagged a bit in the transition from old industrial to new technology [1][2], it appears to be a cultural problem that is acting as friction. Culturally they're not nearly as dynamic on entrepreneurism as Sweden has become. Perhaps it's just easier to change directions at the scale of Sweden than Germany, with all the entrenched institutions and large conglomerates that Germany has.

Same with becoming wildly successful. In America those people are looked up to as role models. In many parts of the EU, being the "tall poppy" is a bad thing.
