In 2012, it was down around 120 yen/GBP -- currently at 180.
So it was a great time to be in London (or the US, or anywhere for that matter)
The USD-JPY exchange rate usually hovers around 100 (it is currently 104 JPY/USD), but back then it dropped all the way down to 75 JPY/USD. Great time to be paid in JPY and visit the US!
