How many Kamen Rider series are there
There are 40 main Kamen Rider TV series in the official numbered lineup, from Kamen Rider (1971) through Kamen Rider Zeztz (2025–2026). The franchise list also includes several remake/reboot entries, but those are usually counted separately from the main series.
Main series count
The numbered official series list shown in the franchise category runs from 01 to 40, ending with Kamen Rider Zeztz. That means the current main total is 40.
Extra entries
Besides the main numbered shows, there are reboot-style titles such as Kamen Rider The First , The Next , Amazons , Black Sun , and Shin Kamen Rider. These are generally treated as special or alternate entries rather than part of the core annual sequence.
