The author will review tephrochronological study on Kazusa Group, the standard Quaternary marine sediments, central Japan, and will point out issues to study in future. The former will be carried out by referring to previous works by each area such as Boso, Tama Hills, Yokohama, Choshi, and underground of central Kanto Plain. Recent studies have focused on description of characteristic properties of tephras and correlation between areas in Kanto district. Moreover, studies for correlation with proximal tephras around source volcanoes had been carried out.
