Of course.
Japan manipulates their currency better than anybody. That's why their export industry, especially in auto, is so successful. On top of that they have a culture whereby if you buy an imported vehicle, there are frequently taxation issues, and there's a whole culture of making sure they buy Japanese vehicles within Japan. So it's structural as it relates to their trade policies, how they deal with trade, but all the decisions they make are geared to a successful export industry.
To the credit of the Japanese citizens, they understand the importance of buying Japanese.
