Time's Nate Rawlings calls it "President Obama's biggest success yet in securing nuclear materials."
According to the BBC, Japan had enough nuclear fuel to make up to 50 nuclear weapons.
As The New York Times notes, Japan is expected to turn over 700 pounds of weapons-grade plutonium and possibly as much as 450 pounds of highly enriched uranium.
Japan is actually returning the materials to the U.S., which originally lent them to Tokyo back in the 1960s for research purposes.
And Iran too, wrapped up in nuclear negotiations of its own, had expressed concerns. As the International Business Times notes, Iranian officials repeatedly accused Japan of a double standard given its stockpile.
On Monday, Italy and Belgium also agreed to transfer their excess nuclear materials to the U.S.
