Japanese markets have been buoyed by recent optimism for a recovery
Japan has revised up its growth data for the April to June quarter, adding to hopes of an economic recovery.
The economy expanded 0.9% during the period, compared to the previous three months. That translates into an annualised growth of 3.8%.
The initial estimate of quarter-on-quarter growth was 0.6%.
Japan has taken aggressive measures in recent months to spur growth in the world's third-biggest economy, after years of stagnation.
