Japan's core consumer prices rose 2.1 percent in September from a year earlier, exceeding the two percent inflation target set by the Japanese government and the Bank of Japan for the first time in nine months, according to government data released on Friday.
The nationwide consumer price index (CPI), excluding fresh food, rose from a 1.7 percent year-on-year growth rate in August, according to the Ministry of Internal Affairs and Communications.
Water and accommodation prices turned from year-on-year declines to increases in September, accounting for most of the growth in core CPI that month. The two rose 4.9 percent and 4.6 percent year on year, respectively, after falling 3.5 percent and 1.4 percent in August.
Food prices, excluding fresh food, rose 2.9 percent year on year, up from 2.7 percent in August.
Experts said as shipping disruptions in the Strait of Hormuz push up international oil prices, related costs will gradually feed through to goods and services prices, and Japan's price increases are expected to widen further by the end of the year.
The warning came as the Japanese government released its energy white paper for fiscal 2025 on Friday, which said Japan's vulnerability in energy supply and demand has once again come to the fore amid escalating tensions in the Middle East.
The white paper said Japan has long relied on the Middle East for more than 90 percent of its crude oil imports. Following the U.S. and Israeli military strikes on Iran in late February this year, shipping through the Strait of Hormuz, a key global energy transit route, was disrupted, creating uncertainty over supplies of crude oil and petroleum products.
To secure domestic energy supplies, the government has released oil reserves and stepped up efforts to procure alternative supplies from regions outside the Middle East since March. These measures helped ensure crude oil supplies to Japan, according to the white paper.
However, concerns over the supply outlook prompted stockpiling of certain petroleum-related products, disrupting distribution and leading to uneven supplies across the country, it said.
