Starting in January, for example, the average household should see energy-related costs -- electricity, gas and gasoline -- fall by about 5,000 yen ($35). Such measures "will lower consumer prices by at least 1.2% over the next year," Kishida said. [...] Preliminary data released on Friday by the Ministry of Internal Affairs and Communications showed that the core consumer price index -- all items minus perishable food -- in the Tokyo metropolitan area rose 3.4% in October from a year earlier, up from 2.8% in September and the highest since 1989. [...] Electricity prices were up 26.9%, while prices of grains rose 10.5% and imported pork increased 7.4%. A leading indicator for nationwide inflation, the latest Tokyo data suggests the country's inflation accelerated this month, as consumer-serving businesses raise prices to cope with higher expenses. In October alone, price hikes were planned for about 6,700 food items, according to a survey by Tokyo-based research firm Teikoku Databank, with many companies attributing the hikes to the weak yen.
