TOKYO (AP) The mood among big Japanese corporations is unexpectedly upbeat despite recent data showing the recovery appears to be stalling.

The Bank of Japan's quarterly "tankan" business survey released Wednesday showed a reading of 15 in June, up from 12 in March, for large manufacturers. Among large non-manufacturers it was 23, versus 19 in March.

Large companies plan to boost their capital investment by 9.3 percent from a year earlier, revised up from minus 1.2 percent in March.

The survey reflects the number of those responding with a favorable assessment of business conditions minus those with a negative assessment. So it is considered a gauge of confidence about the economy.

Many experts the economy may have contracted or stayed flat in the April-June quarter due to weak demand and faltering exports.
