TOKYO: Japan's economy returned to growth in the second quarter, pulling out of its longest recession since World War II, but analysts warned of a rocky road ahead as the nascent recovery was based on short-term stimulus efforts around the world.

The growth was mostly in line with forecasts and added to evidence that Japan was clawing back after being the hardest hit among the major economies due to its reliance on exports.

Growth in the world's No 2 economy is likely to continue in the coming quarters as companies restock inventories due to exports and government stimulus spending around the world.
