The observational research of deep infrared survey using the newly commissioned Subaru Telescope has successfully been performed. After developmental works in the first year, we have mounted an infrared imaging instrument called CISCO on the Cassegrain focus of Subaru Telescope since January of 1999.The comprehensive two-band survey was conducted during the test/adjustment phase of the telescope from April to June, 1999. The obtained images in both the J and K' bands are unprecedently "deep" with very high image qualities, as we expected.Data reductions and scientific discussions are described in the paper to be submitted to a Journal (PASJ), in which we have reported important findings such as, i) fairly small slopes of galaxy count index, but with no definite tendency of flattering, ii) existence of a certain number of extremely red objects, and iii) detection of extreme M sub-dwarfs in the halo region, etc.

利用新委托的斯巴鲁望远镜成功进行了深红外测量观测研究。经过第一年的研制工作，我们于1999年1月在斯巴鲁望远镜的卡塞格伦焦点上安装了一台名为CISCO的红外成像仪。在J和K'波段获得的图像是前所未有的“深”与非常高的图像质量，正如我们所期望的。数据减少和科学讨论中描述的文件提交给一个杂志（PASJ），其中我们报告了重要的发现，如，i）相当小的斜率星系计数指数，但没有明确的趋势，ii）存在一定数量的极红天体，iii）在晕区探测到极M次矮星等。
