Does the 0.3% figure include the massive US military presence? IDK if they count as "immigrants" under the strict definition of the term but most people would consider them immigrants and that might be where a lot of the anti-immigrant sentiment comes from. I would be very surprised if the total amount of immigrants in Japan when including foreign armed services and their family members is a mere 3/10 of a percent.
They get blamed for a lot of crime; idk if that's true or not but it probably is, in part because American culture has less respect for authority, in part because American culture has more respect for individual liberties, and in part because any time you have a large enclave of foreigners (regardless of where they come from or which host nation they're in) they always end up committing more crime than the native population. They also get blamed for driving up prices in the real-estate market (this is definitely true, the US Navy owns 20% of Okinawa).
Blaming "immigrants" instead of specifically blaming the US military is also very convenient for both the US and Japanese government because both governments are largely in-favor of continuing the status quo so it's not surprising that politicians would obfuscate the source of the problem by blaming immigrants as a whole.
