You mean the government lies?

I don't know what all the fuss is about since the rest of the planet has known for decades about the US-Japan agreement to allow nukes to pass through Japan without prior consultation

Foreign Ministry bureaucrats ordered the destruction of copies of a 1960 secret nuclear agreement between Japan and the United States just before the information disclosure law took effect in 2001...

The Japanese government has continually denied the existence of the secret pact, but U.S. documents and statements from former U.S. and Japanese diplomats strongly suggest otherwise...Asahi Shimbun

Reischauer was involved when he was Ambassador to Japan: In Talks with Ambassador Reischauer, Japanese Foreign Minister Agrees to Lie about Nuclear Weapons.

Reischauer embarrassed a lot of people when he publicly disclosed the agreement in 1981. Only the Japanese government continues to officially deny history in the face of overwhelming evidence to the contrary.

Denial of history despite overwhelming evidence to the contrary. Shockingly out of character---if a government can have character.
