Hideyuki Aizawa, chairman of the Financial Reconstruction Commission, said Friday that he will call on the Finance Ministry to maintain the current capital gains tax system in order to prevent the ministry's proposed reforms from negatively affecting the domestic stock market.

"At a time like this, when stock prices are faltering, it is necessary to continue (the system) to prevent investors from fleeing the market," Aizawa told reporters following a Cabinet meeting.

Aizawa said there are many members of the ruling Liberal Democratic Party who support maintaining the current capital gains tax system, and said measures to extend it must be taken as early as possible.
