Two typical climate periods, "Medieval Warm Period (from 11th to 13th Century)" and " Little Ice Age (from 16th to 19th Century)", are treated in this study. Many results which are obtained from Europe and North America, are examined. One of the purpose of this study is to clarify the global climate change precisely. The climate of medieval age and recent age of Japan are clarified by comparing the results of global climate reconstruction and that of Japan. The results of this study are as follows.
Firstly, the historical climate database of Japan has been continued to make, and the new weather data from the diary of "Tadotsu-han" and so on are inputted. And on the "EUROCLIM" , historical climate data base of Europe, their personal computer system are modified to use it more easily. And using these databases, the climate change of "Medieval Warm Period" and "Little Ice Age" in wide area have been able to analyzed.
