The statement is directly confirmed by a primary source, the Bank of Japan's 'Summary of Opinions' from a monetary policy meeting (Source 9), which states an official's view that 'the Bank should set the policy interest rate a little closer to the neutral rate.' This is strongly corroborated by multiple news reports quoting BOJ Governor Ueda signaling his intention to continue raising interest rates, noting the 'distance' to the neutral rate (Sources 1 and 3).
