Tokyo's key consumer price gauge fell 0.9 percent in August from a year earlier for a record 35th consecutive monthly drop, the government said Friday in a preliminary report.

The latest decline in the consumer price index for Tokyo's 23 wards underlies the nation's unabated deflationary trend; consumer prices in Tokyo are regarded as the leading indicator of prices nationwide.

The Tokyo CPI, excluding volatile prices for perishable foods, came to 98 against the 2000 base of 100, the Ministry of Public Management, Home Affairs, Posts and Telecommunications said.
