This is the first report of glacio-eustatic sea-level changes from the shallow-coastal sediments between ca. 1.5 and 1.3 Ma, and the process of stepped intensification of the magnitude of the sea-level change is illustrated clearly for the first time.  Shallow cold-water and relatively deeper warm-water fossil assemblages appear alternatively in the Omma Formation. This mode of occurrence indicates that sea-level rise occurred repeatedly in parallel with a marine climatic warming. These palaeo-water depth changes occurred with a periodicity of a few tens of thousands of years, and the six sea-level rises can be assigned to oxygen isotope stages 49–39, when compared with the oxygen isotope fluctuation curve from the North Atlantic deep-sea sediments records. The first three sea-level changes probably correlate with stages 49, 47 and 45, and had a magnitude of fluctuation of 10–20 m. This was followed by stages 43, 41 and 39, with a magnitude of fluctuations of 50–60 m for stage 43 and 70–80 m for stage 39. The process of intensification of the amplitude is reflected in the increase of the thickness of warm water influx into the Japan Sea at high sea-level stand during this period, which developed from 20–30 m into ca. 100 m."}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1381699993958907648","@type":"Researcher","foaf:name":[{"@value":"Hirokazu
