由于日本的气象站分布密集，而且对甲虫的现代分布研究得很好，因此重建古温度的相互气候范围方法非常适合日本。许多在冰川时期生活在日本低地的适应寒冷的物种仍然在日本列岛的高海拔地区生存，在高山避难所。提出了一种新的绘制凸多边形作为物种包络的方法，使该方法更加准确、客观。本文利用长野县野尻湖遗址地层中的四种甲虫进行了试验分析。该测试显示温度下降，这是东亚的第一个MCR例子。这一结果与以前基于现代山脉重叠和基于植被重建的估计一致。
The Mutual Climatic Range method of Paleotemperature reconstruction is well suited to Japan, because the meteorological stations are densely located, and the modern distributions of beetles are well studied. Many of the cold adapted species which were in the Japanese lowlands during glacial periods still survive at higher elevations on the Japanese Archipelago, in high mountain refuges. A new way of drawing convex polygons as species envelopes is proposed here, make the method more accurate and objective. A test analysis using four beetle species from a stratum in the Nojiri-ko site, Nagano Prefecture is presented. The test shows a decline of temperatures, the first example of MCR from East Asia. The result agrees with the previous estimation based on modern range overlaps and on reconstructions based on vegetation.
