Inter-annual variations in tree-ring cellulose oxygen isotope ratios are in principle dependent only on the two meteorological factors, precipitation isotope ratio and relative humidity, irrespective of differences in tree species. Based on this knowledge, we have established several millennia length of tree-ring cellulose oxygen isotope chronologies all over Japan by analyzing of various types and periods of tree ring samples obtained from wooden materials such as buried natural logs, excavated artefacts and old architectures made of long-living species like cypress and cedar in addition to their living old trees. The newly developed chronologies are now applicable to dating of various species of archaeological wooden materials and in fact have begun to be successfully applied to date many wooden materials excavated from many archaeological sites in various regions, such as Tokai, Hokuriku and Kinki districts since Jomon-era.

树环纤维素氧同位素比的年度变化原则上仅取决于两个气象因素，降水同位素比和相对湿度，而与树种的差异无关。基于这些知识，我们通过分析从木环样本中分析从木环样本中分析从木环样本中分析木环样品的几千年，从木环样品中分析了木环样品，例如埋葬的天然日志，挖掘的人工原料和旧建筑，由塞普拉斯和凯达等长寿物种制成，以及与他们活着的老树。现在，新开发的年代现在适用于各种考古木材材料的约会，实际上，迄今为止已经成功地应用了许多从乔蒙时代以来从Tokai，Hokuriku和Kinki地区等各个地区发掘的许多木制材料。
