The total value of transactions on the Nasdaq Japan stock exchange fell 22 percent to 32.1 billion yen in July, marking the fifth straight monthly decline, according to the Osaka Securities Exchange.
Nasdaq Japan entered its second year in June.
The OSE, Softbank Corp. and the U.S. National Association of Securities Dealers set up the Nasdaq Japan market on June 19, 2000, to help promising venture firms raise funds.
Trading volume also slid 21.2 percent to 7.21 million shares in July.
Despite the new listing of four stocks during the month, including Prestige International Inc., activities slowed in a reflection of lackluster performance in the overall Japanese stock markets.
The monthly trading volume on the first section of the OSE declined 10.9 percent to 658.09 million shares, despite strong performance in such major issues as Rohm Co. and Nintendo Co.
Its trading value also fell 6.4 percent to 1.29 trillion yen.
