I don't think Japan has a Jew problem, so it would be Japanese betraying the Japanese. Japan is so ethnocentric, I would really, honestly, be shocked if after letting in a few thousand Indonesians to work that they would cuck. For example, the whole world was pressuring them to take Muslim refugees, and they told the rest of the world to get fucked, in their typical Japanese way of just not giving any answer to the requests to do so.
