Core consumer prices in Japan were up 0.4 percent on year in June, the Ministry of Internal Affairs and Communications said on Friday.
That beat forecasts for an increase of 0.3 percent on year following the flat annual reading in May.
Overall inflation was up 0.2 percent on year, also topping expectations for a 0.1 percent increase following the 0.3 percent contraction in the previous month.
Both overall CPI and core inflation were flat on month after adding 0.1 percent and 0.2 percent on month, respectively, in May.
