In this research, I have analyzed the semi-strong form efficiency of the government bonds, its futures and Euro yen futures markets by studying impacts of macroeconomic announcements. The sample period is from 1991 to 1998.I have tested whether these markets were affected by news about macroeconomic announcements including BOJ and MOF's open market operation. I have estimated how long these impacts continue, and found that these announcements had impact after 6 business days. These findings show the semi-strong form efficiency hypothesis dose not hold in the government bonds, its futures and Euro yen futures markets.I guess why these markets are not efficient and found that in Japan, the short and long-term government bonds are not issued uniformly. In secondary markets, bonds with more than 7 years to maturity are heavily traded in order to deriver futures. Public sector like the government and central bank have many bonds, so private sector traders via market mechanism do not effectively behave in the markets. To make markets more efficient, individual and foreign traders are invited to these markets and new bonds like non-marketable, stripes and inflation-indexed are necessary to introduce.

在这项研究中，我通过研究宏观经济公告的影响，分析了政府债券、政府债券期货和欧元日元期货市场的半强式效率。样本期为1991年至1998年。我测试了这些市场是否受到宏观经济公告消息的影响，包括日本央行和财政部的公开市场操作。我估计了这些影响会持续多久，发现这些公告在 6 个工作日后就产生了影响。这些发现表明，半强式效率假说在政府债券、政府债券期货和欧元日元期货市场中并不成立。我猜测为什么这些市场没有效率，并发现在日本，短期和长期政府债券并不有效。统一发放。在二级市场上，到期日超过 7 年的债券为了衍生期货而大量交易。政府和央行等公共部门拥有大量债券，因此通过市场机制进行的私营部门交易者无法在市场上有效运作。为了提高市场效率，个人和外国交易者被邀请进入这些市场，并且有必要引入非流通债券、条纹债券和通胀指数债券等新债券。
