Key consumer prices in Tokyo fell 1.1 percent in May from a year earlier for a record 32nd straight month of decline, the government said Friday in a preliminary report.

The core consumer price index for Tokyo's 23 wards -- a leading index of nationwide price moves -- came to 98 against the base of 100 set in 2000, the Public Management, Home Affairs, Posts and Telecommunications Ministry said.

The margin of price fall, excluding volatile prices of perishable foods, equaled that in April but was larger than the 0.7 percent shrinkage registered in March.
