A draft market for only Japan, with JPY currency and a fixed exchange rate extremely exaggerated, 1 USD = 1 JPY (dynamic exchange is about 1 USD = 160 JPY).
An active market for Japan and more countries, that uses local currencies.
If the active market was applied, the shipping rates would be around 1600 JPY (10 USD * 160 exchange rate). However, as you can see at the checkout for a Japanese address, the shipping rate is 10 JPY, because the exchange rate 1 to 1 from the draft market is being applied.
That’s actually quite strange!
