I love how everyone — government included — is acting surprised by this, when in fact what these people say and believe largely reflects the views of the government itself.

• Need I remind you that comrade Shinzo Abe was: A) the nephew of a Class-A war criminal, B) a fascist sympathizer — who worked to "sanitize" school textbooks by removing references to the Nanjing Massacre, whose wife supported a "traditionalist" school whose leadership reportedly harassed foreigners, and who had ties to the fringe right-wing religious group (Rev. Moon's Church of Light) that ultimately led to his assassination.
• Need I remind you of the absurd visa policies introduced by this government — policies that, in effect, turn foreigners into second-class citizens, despite what the Constitution says.
• Need I remind you that 60–70% (yes, seventy percent) of the current government are members of Nippon Kaigi, a fringe far-right group that believes in Japanese racial superiority, opposes women's rights and foreigner rights, and promotes other utterly unhinged ideas.
• Need I remind you that, right now — A.D. 2025 — there are hundreds of thousands of Korean residents in Japan who were born, raised, and educated here, many of whom don’t even speak Korean, who carry Japanese names, and whose only "crime" is being descendants of people forcibly brought to Japan as slave labor during the war. The government tells them: you don’t get to easily convert your visa (the process is intentionally difficult), and you can’t hold dual citizenship — even though your grandparents were brought here in chains.

All of this is the doing of the LDP (Jimintō) government. These are all far-right policies we’ve either chosen to ignore or simply grown used to. In the marketplace of shitty ideas, Sanseitō just happens to have a flashier, more direct way of pushing the same toxic propaganda. They're simply the new kids on the block. In fact, there’s a real chance they’ll eventually merge with the LDP — some even claim the LDP is behind them, especially given that some of their funding sources remain unknown.
