The head of a minor opposition party whose primary goal is to "crush" NHK made a remark hinting that genocide is the solution to overpopulation in a video uploaded to YouTube on Friday.

"To put it very roughly, we should just wipe out races that have babies like idiots, or something like that," Takashi Tachibana of NHK Kara Kokumin o Mamoru To (the Party to Protect the People from NHK) said in the video, adding that he has "no motivation to do so though."

Tachibana also questioned the provision of educational support to countries in poverty.

"It's impossible to teach dogs. (They're) close to being dogs. There are an overwhelming number of people like that in the world," he said, adding, "These countries have babies to the point of idiocy."

In a separate video discussing racism, Tachibana suggests that discrimination and bullying are forms of divine providence.

"Isn't it good for things to be natural? The natural order God created. People killing each other is part of God's system, too," he said.

Tachibana, a former employee of the public broadcaster, is known for making inflammatory remarks about TV personalities and those who oppose him on his YouTube channel.

His party calls for the abolishment of mandatory payments of subscription fees to NHK, arguing that only those who watch the network should have to pay.

The party received around 980,000 votes in the proportional representation system in the July 21 Upper House election.
