Don't know bout that but I can confirm that the majority of Westerners there are leftists and organize leftist protests whenever they can like BLM and LGBTBBQ protests and try to recruit the Japanese youth to join with little success, the Japanese dislike it for being disruptive to people's lives and too aggressive. The last BLM protest had around 2k people and was 98% non native born, some "indie" leftist news thing even had an Canadian Japanese person try and pretend to be native when they livestreamed it but her accent was too obvious to be a believable native speaker with a few mistakes and she had a BUNCH of visible tattoos which is frowned upon heavily in Japan to the point of barring you from certain places.
