The 26-29-ka Aira-Tn (AT) and 7.3-ka Kikai-Akahoya (K-Ah) tephra, and degree of weathering involved in the terrace chronology that most terraces were formed in the Oxygen Marine Isotope Stage (MIS) 4-2, or otherwise in MIS 6. No valley filling would have occurred during such a glacial period. The late Quaternary uplift rate of the east Shikoku Range exceeded 0.45mm/year and reached 0.9-1.0mm/year at the maximum.
