Using Tandetron II at Nagoya University, we measured radiocarbon ages of three xylographic books printed in the early years of the Edo period. The books A, B and C belong to our collection of ancient Japanese paper. According to the form of printing blocks, the publication of the book A is estimated to be in the Keichou era AD1596-1615. The published ages written in the books B and C are AD1669 and AD1658,respectively. Measured ^<14>C ages of the books A, B and C are 362±21,260±23 and 262±22 BP. The radiocarbon age calibration curve transforms these ^<14>C ages in BP into ages in AD. Since the curve is bent in three at around 350 BP, the average ^<14>C age of the book A is transformed into three ages in AD and the error region is transformed into two regions. Considering the probability density in the error region, we selected one average value in each error region for simplicity. Since the ^<14>C ages of the books B and C lies on a steep straight line of the calibration curve, the errors of calibrated ages in AD are very small. The transformed ages in AD are 1490^<+29>_<-11> and 1610^<+12>_<-26> for A, 1649±8 for B and 1648±8 for C. The shape of printed Chinese characters suggests that the book A was not made before AD1593. The latter region 1610^<+12>_<-26> fits the age of the book A. The difference between the measured age AD1649±8 and the written year AD1669 is 20±8 years, that is, between 12 and 28 years for the book B. The 12 years are a little longer than we expected. For the book C the same difference is 10±8 years, that is years between 2 and 18. This difference includes our estimated years between the year cutting trees to make Japanese paper and the printed year of AD1669. Our estimated years are from one to several years.
