TOKYO - Japanese automaking giant Toyota Motor posted a 39% increase in profit for its fiscal fourth quarter but has warned that its explosive global sales growth could slow in the next 12 months as key US and Asian auto markets cool.
   Q4 net profit was ¥404.1 billion ($3.44bn; €2.7bn; £1.84bn), up from ¥290bn a year earlier. Revenue for the period rose 18% to ¥5.75 trillion yen ($48.9bn).
