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.

树木年轮纤维素氧同位素比率的年际变化原则上只取决于降水同位素比率和相对湿度这两个气象因素，而与树种的差异无关。基于这一认识，我们通过分析不同类型和不同时期的树轮样品，建立了日本各地数千年的树轮纤维素氧同位素年代学，这些样品来自木质材料，如埋藏的天然原木、出土的文物和由柏木和雪松等长寿物种制成的古建筑，以及它们活的老树。新开发的年表现在适用于各种考古木质材料的测年，实际上已经开始成功地应用于自绳索时代以来从不同地区的许多考古遗址出土的许多木质材料，例如东海、北陆和近海地区。
