Is the Fed Using Repo Market to Secretly Help Japan Dump Treasuries?

Japan is in trouble. Their yen is collapsing as they are trying to maintain yield curve control. And so, they intervened to prop up the value of the yen for the first time in decades last week. Now, it turns out that the Federal Reserve may be assisting them. As Bloomberg points out, Japan may have a pile of dollars it can tap at the Fed's reverse repurchase facility, accessible by foreign central banks. However, I think what Bloomberg is talking about here is actually the opposite of what's going on at the reverse repo facility. There is not enough evidence that Japan has any significant amount of money with the Fed. Instead, it looks like the Fed is going to have to be actively assisting Japan with dumping those Treasuries, using the opposite the repo facility, specifically the one for foreign central banks.
