I think their current posted fees are 1.4% spread-only ($14 for $1000) or 0.3% spread plus core fees. I can't quite tell from the rate sheet but looks like 550 JPY for a 100,000 JPY trade. I guess that would work out to about … $8.50 per $1000? Is that right?
If you have a local bank that allows foreign depositors to exchange at 0.3 JPY/1 USD, does that mean you pay about $2.50 to convert 1000 USD?
