To analyze the origin and evolution of Japanese small mammals, we studied morphological, cytogenetical, molecular, biochemical, and parasitological data sets. There are many candidates that represents the derivatives of the ancestral species that came through the "Himalayan Corridor" to Japan. Among them, the species complex of Japanese Microtus montebelli and its allies, M..kikuchii from Taiwan, M.oeconomus from Russia, and M.sikimensis from Nepal, is one of the most suitable species for the study. Morphological, karyological, and parasitological findings confirms a close relation between M.montebelli, M.oeconomus, and M.kikuchii. This conclusion also denies the origin of M.montebelli from M.arvalis or M.fortis. Other species of Japanese small mammals also studied and discussed from various points of view through this study.

为了分析日本小型哺乳动物的起源和进化，我们研究了形态学、细胞遗传学、分子生物学、生物化学和寄生虫学数据集。有许多候选物种代表了通过“喜马拉雅走廊”来到日本的祖先物种的衍生物。其中，日本蒙特贝勒鼠及其同族、台湾菊池鼠、俄罗斯经济鼠和尼泊尔斯基金鼠的种群是最适合研究的种之一。形态学、核生物学和寄生虫学研究结果证实蒙特贝利m.s okeconomus和菊池m.s有密切的关系。这一结论也否认蒙特贝利分枝杆菌起源于阿瓦利分枝杆菌或富通分枝杆菌。通过本研究，对日本其他种类的小型哺乳动物也进行了多角度的研究和探讨。
