Bank of Japan policymakers meet next week for that most delicate of monetary missions - raising inflationary expectations without scaring households into cutting back consumption.
The Bank of Japan cut next fiscal year's inflation forecast on Wednesday and expanded a loan scheme aimed at boosting lending, acting to deflect criticism that it is sitting idly as slumping oil prices keep inflation well short of its target.
