A friend who has actually been living in Japan for many years tells me that
ordinary Japanese ATMs deliver money in 10,000-Yen bills. 10,000 Yen is
around US$100.
He thinks the individual withdrawal limit is about US$50,000 a day (which,
he adds helpfully, “should be enough, unless you are bribing a politician”).
However, he says that the most himself has ever withdrawn on any particular
day was US$12,000. “The machine didn’t even blink.”
