USD to JPY in August 2026: high, low, average

Updated September 26, 2026

The dollar bought 158.8 Japanese yen on average in August 2026, according to cross rates calculated from 21 European Central Bank fixings. The month opened at the low and closed at the high: 156.68 yen on August 3 and 159.73 yen on August 31, a rise of 1.95% from first to last day.

A month that climbed from its first day

August started with a sharp move. On August 3 the rate fell 2.22% against the last fixing of July, the largest daily change of the month, and that drop set the monthly low of 156.68. From there the dollar recovered steadily. It rose on 14 of the 21 fixings and fell on only 7.

Because the low came first and the high came last, the range from low to high (1.95%) equals the change across the month. That pattern is uncommon, and it means anyone who waited through August to buy yen with dollars got more yen at the end.

The bigger picture: July 2026 and August 2025

PeriodAverage USD/JPY
August 2025147.7
July 2026162.51
August 2026158.8

Against July, August was a weaker month for the dollar: the July average of 162.51 was higher than August's 158.8, a fall of 2.28%. Against August 2025 the dollar was much stronger, with the average up 7.52% from 147.7.

So a traveller who changed dollars into yen in August 2026 got fewer yen than in July but far more than a year earlier.

Reading the numbers if you travel to Japan

For a trip paid in yen, a higher USD/JPY rate is good news for a dollar holder, since each dollar converts into more yen. In August 2026 the best reference day was the last one, August 31, at 159.73. The worst was August 3, at 156.68.

For someone paid in yen who spends dollars, the reverse holds. The start of the month, when a dollar cost the fewest yen, was the cheaper time to buy dollars.

Card issuers and airport exchange desks add their margin to these reference levels, so treat the ECB-based figure as a yardstick. If your receipt shows a rate far below the fixing of the same day, the difference is the fee.
