It’s amplified by the fact that it’s an island so foreigners are scarce
First off, in these times, being an island doesn’t mean anything, so that is not an excuse actually. Second, I have heard that their own policy regarding taking non-Japanese in made them a bit more isolated.
In modern times it might not matter (or rather, it matters less, refugees still have to move to the closest country and distance by sea does matter), but it mattered in the past and they grew up as a very isolated society (which in turn had them spawn those laws you’re talking about).
