Tokyo, July 25 (BridgeNews) - Japan's June corporate service price index averaged 95.9 (1995=100), down 1.0% on the year and down 0.1% on the month, the Bank of Japan said. The 1.0% fall on the year in the June CSPI was the largest one since November 1999 when it had declined 1.1%, BOJ said. The June figures confirm deflationary pressure remains strong, and weakening in domestic demand is partially responsible for the recent CSPI falls.
