One of the main ways that Zaitokukai has been able to popularize anti-Korean sentiment is through its use of the internet. The group has a strong online presence, and its members use social media and other platforms to spread their message. They often post inflammatory content, such as videos of Koreans being attacked or articles claiming that Koreans are responsible for various social and economic problems in Japan.
Zaitokukai has also been able to spread its message through its offline activities. The group holds regular demonstrations and protests, often targeting Korean businesses or neighborhoods. They also distribute flyers and other materials that promote their anti-Korean views.
The group's efforts have been successful in stirring up anti-Korean sentiment in Japan. In recent years, there have been a number of high-profile cases of violence against Koreans in Japan. In 2016, for example, a Korean man was stabbed to death in a Tokyo subway station by a man who was later found to be a member of Zaitokukai.
The Japanese government has been criticized for not doing enough to address the problem of anti-Korean sentiment in the country. Some critics argue that the government is reluctant to take action because Zaitokukai and other far-right groups have support from some powerful politicians and business leaders.
The rise of anti-Korean sentiment in Japan is a serious concern, and it has the potential to damage relations between the two countries. The government must take action to address this problem, and it must send a clear message that anti-Korean sentiment is not tolerated.
