Apart from the Great Kanto Earthquake, Japan was devastated.

 During the Japanese colonial period, there was a big earthquake in the Kanto region of Japan (the so-called metropolitan area centered on Tokyo), and Tokyo was almost devastated. At that time, the Japanese government used the sly method of public agitation that it had always used to break through the crisis. Koreans living in Japan were preparing for an armed uprising and advertised that an earthquake occurred. They also instigated the Korean people to plan the outbreak of infectious diseases by putting dead animal corpses in the well with poison. After the earthquake, there were rampant rumors that Koreans were committing looting and arson. I don't know if it's because of that, but anyway, in order to reverse the internal conflict, there was a phenomenon of bullying the weak groups peculiar to Japan. It is said that a so-called vigilante group was formed and brutally slaughtered with bamboo spears and sticks as soon as Koreans were seen. It is said that they went crazy around the collective residence of Koreans. It is said that Koreans were mainly living miserable in places such as rivers and landfills. At that time, the vigilante groups mainly pronounced the cheekbones protruding from the face and the Japanese pronunciation in order to distinguish between Japanese and Koreans. It seems that Korean people's facial contour is thicker and the jaw area, which is the mandible, is developed, making it easier to distinguish them from Japanese. Also, unless you are born and studied Japanese locally, it is said that Koreans are not good at pronouncing local words. It is said that many Koreans died unjustly at this time. There are no exact statistics on how many people have died.   However, there were not only Koreans, but also the lower-class Japanese villagers, the untouchable people, and the vagrants from the provinces. It is said that the group also sacrificed a lot along with the people of Korea by speaking different patterns such as dialects and slang that are different from the Tokyo dialect.    I don't know if history repeats itself, but similar rumors circulated during the last Kobe earthquake. Groundless rumors spread that Koreans in Japan loot money and goods in earthquake-stricken areas.

People in neighboring countries are happy when a large earthquake occurs in Japan these days because of this. In the end, it was karma.
