When the value of the yen strengthens relative to the value of dollars, American goods become relatively cheaper for Japanese consumers, which can lead to an increase in exports from the U.S. Conversely, Japanese goods become relatively more expensive for American consumers, which can lead to a decrease in imports from Japan.
When the value of the yen strengthens relative to the value of dollars, it means that you would need fewer yen to buy a dollar. This indicates that the yen has appreciated or become stronger compared to the dollar. In practical terms, this means that if the value of yen strengthens, American goods become relatively cheaper for Japanese consumers, which can lead to an increase in exports from the U.S.
For example, let's say the exchange rate is 100 yen per dollar. If the value of the yen strengthens to 90 yen per dollar, it means that now you would need only 90 yen to buy one dollar. This would make American goods more affordable for Japanese consumers.
On the other hand, if the value of yen strengthens, it also means that Japanese goods become relatively more expensive for American consumers. This can lead to a decrease in imports from Japan.
