A currency is said to be appreciated when its value against some foreign currency increases.
When the value of the yen appreciates, it becomes more expensive for people in Country J to buy Company T automobiles. So consumers of Country J would increase imports and decrease their demand for domestic automobiles. As a result, the quantity demanded of Company T automobiles would decline. And it would lead to a decline in the profits made by Company T.
Therefore, there would be a fall in Company T's profits due to appreciation of the yen.
If the exchange value of the yen appreciated, the automobiles produced by Company T would become more expensive than other automobiles. So consumers of Country J would raise imports and reduce their demand of Company T automobiles. This would lead to a fall in the quantity demanded for automobiles, thereby negatively affecting the profits of Company T. As a result, Company T profits would decline.
