Bank of Japan Gov. Masaru Hayami on Monday said he does not think Japan's major banks are short of capital, but cautioned they need to make further efforts to increase profitability.

"We think the capital adequacy ratio of Japan's major banks (operating internationally) exceeded the 10 percent level" as shown in bank audits by the Financial Services Agency, Hayami said at a regular news conference.

The results of special FSA bank audits, released Friday, put the capital adequacy ratios between 10 percent and 11 percent.
