Japanese Yen has been strong against US dollar and Euro since economy crash in U.S.A.
It sounds good for Japan, however it is bad thing for Japanese exporter like us.
We don't raise price of our product, however automatically price of our product is going up for our customers.
We couldn't do anything and it's beyond our control.
Actually Japanese economy is not strong as money investor to think.
Consumer mind in Japan has been week.
So we just wait until exchange rate would be back to normal.
