Impact on Japan of a volatile yen
Japan's quarterly growth figures for the first three months of the year have been revised up.
The positive data adds to signs that Prime Minister Shinzo Abe's economic revival plans - dubbed "Abenomics" - are having the desired effect on the world's third largest economy.
The data comes on the back of a series of recent aggressive policy moves, which have resulted in a sharp decline in the yen's value.
The Japanese currency has fallen nearly 25% against the US dollar since November last year.
Nomura's Stuart Oakley told the Asia Business Report that the yen's weakness will have a positive impact on the country's exports.
