Japan’s exports of cars, trucks and buses fell for the first time in 15 months in March, due to weaker demand and a continuing shift of production out of Japan to overseas facilities.

According to data issued by JAMA, exports fell 0.1% in March from the same month a year earlier to 394,816 units.

Toyota is said to be planning to cut domestic output by 6% this business year as it shifts more of its production overseas. The shift in production overseas is being seen as bad news for Japan’s economy, which is already suffering from high unemployment and has relied significantly on exports for its marginal growth.
