NARA, Japan, Feb 8 (Reuters) - Bank of Japan (BOJ) Deputy Governor Shinichi Uchida said on Thursday the central bank is unlikely to raise interest rates aggressively, even after ending its negative interest rate policy.

If sustained achievement of its 2% inflation target comes into sight, it would also be "natural" for the BOJ to end its purchases of risky assets such as exchange-traded funds (ETF) and trust funds investing in property, Uchida said in a speech to business leaders in Nara, western Japan.
