Core consumer prices in Tokyo increased 1.9 percent in April from a year earlier, the fastest pace in over seven years, accelerated by rises in crude oil and material prices, government data showed Friday.
The core consumer price index excluding volatile fresh food items marked the eighth straight month of year-on-year gain and the largest growth since March 2015, the Ministry of Internal Affairs and Communications said in a preliminary report.
The rise close to the Bank of Japan's 2 percent inflation target also resulted from the waning effect of sharply lower mobile phone fees that began last spring.
Among energy prices, which jumped 24.6 percent, electricity fees surged 25.8 percent, city gas fees soared 27.6 percent and kerosene prices climbed 21.0 percent.
Tokyo's CPI data is seen as an indicator of Japan's CPI, set for release on May 20.
