TOKYO -- A steady decline in the yen is proving a godsend for exporters such as Toyota and has won solid support from Japan's main trading partners, who are betting the impact on their own currencies will be offset by gains from a recovery in the world's third-largest economy.

It's not such good news for entrepreneurs like Thamonwan Thawornthaweewong, whose Angry Bird fish balls and squid rings now cost more to sell in Japan.

The yen slipped past 100 to the U.S. dollar earlier this month and is now hovering near 102 yen per dollar.

Countries across Asia are seeing their own currencies pushed higher, as financial markets are flooded with cash pumped out by Japan to help double the country's monetary base and hit a 2 percent inflation target.
