Showa and Heisei are era defined by the life of the Japanese emperor. Showa died in 1989, so Turboranger is the last Showa series. Fiveman is the first Heisei series. Neo-Heisei just refers to Kamen Rider's format change from W onwards, with the franchise no longer referred to as Masked Rider. I suppose Sentai's equivalent is Go-Busters.
