The package is likely to include subsidies for companies to establish facilities in Japan and help for Japanese corporations wishing to take stakes in foreign energy projects, Kyodo news said, citing unnamed officials.

The strength of the Japanese currency, which in August hit a post-war high against the US dollar, has walloped outward-facing manufacturers in a country that is heavily dependent on exports.

A high yen makes Japanese products expensive for overseas buyers and diminishes the value of repatriated profits. But it also makes foreign purchases more attractive for companies wishing to expand overseas.

In his inaugural policy speech last week, Prime Minister Yoshihiko Noda said the rise of the unit meant Japan was facing "a crisis of unprecedented industrial hollowing-out".

He warned that unless measures are taken "domestic industries could go downhill and jobs could be lost. If that happens, it would be almost impossible to break out of deflation and reconstruct areas" affected by the March 11 quake and tsunami.

The yen has rocketed in value over recent months as financial uncertainty in Europe and the United States continues to send global traders scurrying into the safe-haven currency.

Despite three interventions in the markets in the past year, two of which were carried out by Tokyo alone, the yen has remained strong.

On Tuesday, the unit was trading at 76.56 yen to the dollar.

Kyodo said the measures will be financed by a planned extra budget, which will also help pay for the reconstruction of areas damaged by the March disasters.
