One giveaway is that two of the vans fly Rising Sun flags, the one with red rays radiating from a central sun on a white background. Once the symbol of Japanese military imperialism, these days the Kyokujitsu-ki is often flown by those with, let’s say, a misguided sense of patriotism, and it is especially provocative for the Koreans and the Chinese (the Japanese Maritime Self-Defense Force ships also fly it, which as you can imagine causes problems when they take part in joint events with the Korean navy).
