When the Bank of Japan ended its "zero-interest-rate" policy at its two-day Policy Board meeting last month, Nobuyuki Nakahara recalled the last time the central bank made the same move, when he was a board member in August 2000.

Nakahara was one of two Policy Board members who voted against changing the policy in 2000, and he again believes the BOJ "should have waited another two to three months" before ending the zero-rate policy this time.

The former president of Tonen Corp. -- now TonenGeneral Sekiyu K.K. -- served on the Policy Board from April 1998 to March 2002.
