Japan's economy is expected to have grown for a second quarter in January-March, supported by recovering exports and solid domestic demand, although the full impact of the Iran war had yet to be felt, a Reuters poll showed on Friday. • Gross domestic product (GDP) in real terms likely expanded an annualised 1.7% in the first quarter, according to the median forecast of 17 economists, after a 1.3% expansion in October-December. • Without annualisation, the January-March growth rate was estimated at 0.4%.
