The nationwide core consumer price index (CPI), which excludes fresh food costs, rose 3.3% in June from a year earlier, matching a median market forecast.
A hike in utility bills added to a steady increase in food and daily necessity prices, adding to the burden of households.
But so-called "core core" inflation, which strips away both fresh food and fuel costs, slowed 4.2% in June from a 4.3% rise in May, a sign the rapid pace of increase seen in the past few months was moderating.
As inflation perks up, markets are simmering with speculation the BOJ could soon phase out its controversial yield curve control (YCC) policy that is criticised for distorting market pricing and narrowing margins for financial institution.
Under YCC, the BOJ guides short-term interest rates at -0.1% and buys huge amounts of government bonds to cap the 10-year bond yield around 0% as part of efforts to fire up inflation to its 2% target.
