Toyota Motor Corp. President Akio Toyoda, whose company has accumulated a cash pile of almost ¥4 trillion, is facing calls to put that money to better use.

The world's largest carmaker is seeing profits surge as the yen weakens and demand rises in the U.S. and China.

Toyoda's reluctance to spend has prompted the likes of Takaki Nakanishi, Institutional Investor magazine's top-ranked Japanese auto analyst, to say Toyota should return more money to shareholders or increase capital investments.
