对日本中部过去800年的冬季温度和夏季降水进行了重建，从绝对年轮宽度年表恢复到了公元1177年。这份年表是由300年前的活树和起源于早期、现代和中世纪的古老原木组成的，这些原木成百上千地存在于山脚下的基索森林中。Ontake(3063 m a.s.l)与欧洲过去的气候变化基本一致，重建的冬季温度表现出三个明显不同的阶段，即可能对应于中世纪暖纪元的结束的12世纪中期的降温趋势，随后是与小冰期相对应的长时间寒流，直到19世纪初，然后是持续到现在的明显变暖趋势。
Annually resolved winter temperature and summer precipitation of Central Japan were reconstructed for the past 800 years, back to AD 1177 from an absolutely dated ring-width chronology of Chamaecyparis obtusa. This chronology was constructed from 300-year-old living trees and old logs of early modern and medieval origins that exist in hundreds in the Kiso Forest on the foothills of Mt. Ontake (3,063 m a.s.l.). In general agreement with the well established past climatic change in Europe, the reconstructed winter temperature showed three distinctively different phases, i.e. a cooling trend toward the mid 1200s possibly corresponding to the termination of the Medieval Warm Epoch, followed by a long cold spell corresponding to the Little Ice Age till the early 1800s, and then by a conspicuous warming trend continuing up to present.
