Japanese-Brazilians in Japan

The Sunday of my homestay was a sports day at the local elementary school. And my family's house was next to the hospital. So, the crazy Right-wingers drove their bus around playing loud music and going off on the loudspeakers about how the nurses at the hospital are raking in the dough and cheating the country out of money. They were all wearing camouflage. If they'd known I was foreign they probably would've yelled at me while I walked the dog. But I don't think my Japanese is quick enough to spout out some interesting response. My English isn't that quick, either, for that matter.
