The international exchange will change everyday,
but the source of the original data is the same, the numbers are the same in Japan.

The important thing is that the actual exchange fee is different at the place of exchanges
and there are very few places where you can exchange fr THB to JPY even in Japan.

One Japanese traveler said exchange in Japan is not good. (just not worst)
Exchange up to 100,000Y, you can do at nearest Familymart in Tokyo and around.

It is cheap now by looking through last year.

Although it was cheaper than now in 2015, there is not much difference,

so there is no impact unless it is a large amount.
