Research Abstract	This resarch has studied the performance of the Japanese stock market. On the basis of intra-daily data of the Tokyo Stock Exchange (TSE), it has found that tere is positive serial correlation if subsequent price changes of less actively traded stocks, while there is a nagative correlation in more actively traded stocks. It has also hound that in the Over-the-Counter (OTC) market, where no market orders are permissible, there is no negative serial correlation even for most actively traded stocks. Becouse there is no obligatory market making in Japan, the difference in price behavior between different segments of the market reflects the presence or absence of boluntary market making activity. In this context, it tis pointed out that the liquidity of Japan's regional exchanges is severely limited.
