 note = {The 14C age of subfossil Thujopsis dorabrata wood from North Japan，was measured by AMS for annual tree-ring samples from the period of AD 1381 to 1449. The data were compared with the IntCal09 ca1ibration curve. As a result, the 14C age of these samples showed the old date from IntCal09 for about 35 years on the average. This result suggests that the regional effect existed in this area. The measurements of the further North Japanese samples are necessary to improve precision of calibration of 14C age in Japan., 名古屋大学年代測定総合研究センターシンポジウム報告},
