Reuters reported that the Bank of Japan Governor Haruhiko Kuroda said on Tuesday the central bank must maintain ultra-loose monetary policy, while keeping an eye on the risk that inflation accelerates before wages begin to rise.

''Speaking in parliament, Kuroda also said he did not think Japan was experiencing an "abnormal" weak yen that pushes up import costs excessively, stressing that recent rising living costs were driven mostly by higher commodity and energy costs.''

BoJ will continue easy monetary policy so economic recovery pushes up wages and leads to gradual rise in consumer inflation.
