If U remember, Japanese "intervention" did nothing last time...in fact, it kind of triggered this whole currency debasement thingy...ie hyperinflation
All that happened last time the Japs bought US treasuries, was that the rest of the world sold them by the billions...and silver and gold have gone crazy ever since...probably Russia, China, Brazil, etc...replacing $us from reserves with silver and gold...my humble recollection...I'm not worried, anyway.
