[3] It has been described by the National Police Agency as a potential threat to public order due to its "extreme nationalist and xenophobic" ideology.

[citation needed] Sharon Yoon and Yuki Asahina argue that Zaitokukai quickly succeeded in framing Korean minorities as undeserving recipients of Japanese welfare benefits.

[1] Sakurai founded Zaitokukai after seeing a TV news report on a group of Japanese citizens organizing to support the Zainichi Koreans who brought a lawsuit to obtain national pensions without making any premium payments.

In September 2009, it held a demonstration in Akihabara calling for the resistance to granting suffrage to non-citizen foreign nationals with about 1,000 participants, according to Sakurai himself.

[11] Some time before that, Zaitokukai held a counter-protest against a demonstration by more than 3,000 in Ginza, Tokyo, organized by Mindan (the Korean Residents Union in Japan) to extend suffrage to foreigners.

[13] Zaitokukai alleges that Zainichi Koreans have special legal rights granted to them through the process of their integration into the Japanese society.

It argues that Zainichi Koreans wrongfully claim those rights by saying that they are a deprived and discriminated minority in Japanese society.

[19] A writer for Vice News pointed out they tend to focus on Zainichi Koreans to the exclusion of other groups that might violate immigration statutes.

[4] On December 4, 2009, four members of Zaitokukai were arrested for harassing Korean students in Minami Ward, Kyoto,[23][24] at a pro-DPRK school.
