>You can get residency semi-easily but getting citizenship is extremely hard.
As far as I can tell from the description of the procedures involved, it's actually easy - and certainly easier than the US, and it requires less time in the country to apply than some European countries. One reason why it's uncommon however could be because Japan does not allow dual citizenship, and it's harder to get into the country in the first place other than teaching English.
