Prime Minister TAKAICHI said on Friday the government will continue to closely monitor exchange-rate and price trends and take appropriate measures, responding in the Diet to an opposition question on economic policy and risks from yen depreciation.

TAKAICHI, previously a proponent of looser fiscal and monetary settings, is facing market pressure to adjust policy direction.
