Note 62 — Chapter VIII

The average yield of the three kinds at Government experimental farms—the middle variety yields best and next comes the late variety—is about 2½ koku per tan or roughly (a koku being about 5 bushels and a tan about a quarter of an acre) about 45 bushels per acre. The average yield of ordinary rice in Japan in an ordinary year is 40¾ bushels. In the bumper year of 1920 the average yield was 41⅓ bushels. In the year 1916 (to which most of the figures in this book, apart from the Appendix and footnotes, in which the latest available figures are given, refer) there was produced 58¼ million koku of all kinds of rice, the value of which was 826½ million yen. The normal yield (average of 7 years, excluding the years of highest and lowest production) is 54½ million koku. See Appendix XV.
