Japanese stocks have seen sharp falls in response to the Bank of Japan’s attempts to curb the rising yen.
In Tokyo, the Nikkei 225 index fell more than 3.5%, hitting a fresh 16-month low.
On Monday, Japan’s central bank announced plans to boost low-interest lending, in an effort to bring down the value of the currency.
But the yen remains at 15-year highs and investors are concerned over the impact that could have on exporters.
A strong yen makes Japanese goods more expensive abroad, hitting exporters’ profits.
Electronics giant Sony was hit by the sell-off, losing 3.66% of its share price.
Car maker Toyota was down nearly 2.4%, while Toshiba lost 4.7%.
The Bank of Japan said it would boost cheap lending to commercial banks by 10 trillion yen ($117bn; £75bn), in an attempt to ease pressure on the yen.
The Japanese government also said it would initiate a further 920 billion yen of stimulus measures.
But BBC Tokyo correspondent Roland Buerk said the move had been seen as a “tokenistic gesture” by investors.
“Government ministers here have been trying to talk down the yen,” he said.
“They have said they will take decisive action, [but] the problem is that the limited action they have taken so far has looked anything but decisive.”
