Compared chronologically between the cooling periods and the calibrated dates of earthenware typesfrom the late phase of the late Jomon period to the early Yayoi period in the Hokuriku District, it can befound that: (i) the boundary dates (1350 cal BC) between both the cooling period of 1400 to 1350 cal BCand the Inoguchi II /Yokaichi-shimbo types closely correlate to each other; (ii) the boundary date (900cal BC) between the cooling period of 900 cal BC and the Nakaya/Shimono type are also correlated;and, (iii) the boundary dates (800 cal BC) between the cooling period of 850 to 700 cal BC and theShimono/Nagatake type also show a similar correlation. Cooling resulting from decreases in solaroutput seriously affected the livelihood of the Jomon people. I have hypothesized that in the criticalsituation described above, the Jomon people changed the patterns earthenware, patterning tools, andthe positions onto which print/patterns were inscribed as part of their prayers for regeneration; and,consequently that the types of earthenware changed chronologically. However, there are three boundary dates in which no evidence of the occurrence of a cooling periodwas found, despite changes in earthenware types; one is the boundary date (1300 cal BC) between theYokaichi-shimbo type and the Okyoduka type, another is the boundary date (1100 cal BC) between theOkyoduka type and the Nakaya type, and the other is that (600 cal BC) between the Nagatake typeand the Shibayama-demura type. Changes in these earthenware types conceivably resulted from othercauses which are yet to be determined.
