That is mostly correct; immigrants account for about 3% of a total 123mil population. Your point does stand, but we are quite visible in Japan -- especially in Tokyo.

You are correct that we do not threaten jobs either. A large majority of the foreign population is working low/unskilled jobs. Generally, the native population is generally not wanting those jobs.

Those undesirable jobs can also be highly visible. Maybe the most frequent place Japanese notice visible minority immigrants is at convenience stores. So maybe it makes the population feel overrepresented. I see RWers post frequently about convenience store workers at least.

In Japan, the popular sentiment on immigration tends to be grouped together with tourists and temporary foreign workers as a single category: foreigners. This is perhaps understandable but unfortunate, because tourists often are very visible and tend to make a bad impression, as most haven't studied the language or learned the numerous behaviour expectations. Bad experiences with tourists creates hostility towards immigrants, who are few and mostly do work hard to integrate and behave well.

Tourists are short-term visitors who are there exclusively to spend their money in Japan and leave it with its citizens. If the Japanese do not want that because the tourists don't come fully prepared for living in Japan, then you should just deny tourist entries to the country. It would be win-win for everyone, because there are plenty of other countries who would gladly take those tourists instead.

I'm sure the Sanseito party would be happy to add your proposal to their platform. I doubt the people who work in the tourism industry are voting for them anyway, and the people who benefit indirectly from tourism probably aren't aware enough of the dependency to care about it.

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.

The entire US military presence in Japan (service members, dependents, and contractors) is around 100k people, or roughly 0.08% of Japan's population.
