Kamikaji, Ai (2003). "Review of Chikamatsu: Five Late Plays". Bulletin of the School of Oriental and African Studies, University of London. 66 (3): 520–522. ISSN0041-977X. "[...] all the reliable sources I have found in Japan clearly state that Chikamatsu died in 1724, even while quoting the playwright's age at death as 72. In traditional Japanese calculations of age, a new born baby is one year old in its first year of life with a year added to its age every New Year's Day. Therefore, I feel that perhaps it should be explained that in terms of the Gregorian calendar Chikamatsu died aged 71 in 1724."
