I know these three Riders are made in Heisei Era (1989 onwards) but I dont known is why many fans consider this three as Showa on the internet ? Meybe they dont know much about Japanese history?.
We to remember that Showa is a time period not just a name but I think I know why this fans Would consider them as showa because of Ishinomori's involement in this film but if that is the case then Fans should also consider Kuuga and Agito as part of Showa even the are made in Heisei due to significant similarities to their predecessors's approach as well as Ishinomori's involement in Kuuga before his death. But for now I just consider this movies as Heisei and I don't care what this fans think and after all they are wrong.
Toei officially lists Shin, ZO and J as Showa Riders, despite the fact they were made in Heisei years.
Why this is so is only know to the people who make these kinds of decisions at Toei.
This, of course, means ZO must storm the Hikari Studio and demand help in getting a petition to figure out why he is called "Showa" when he was clearly created in Heisei times.

Toei grouped Ichigo-J as Showa Riders, and Kuuga onwards as Heisei
the Net Movies tend to have Toei poke fun at themselves a lot (Narutakis Onore Dekeido with he fan in his face, Telling Kuugas real suit actor apart from he others by their butts, Diend looking for a bike, Stronger petioning Tackle to be a Rider). RX DID air in the Heisei era, but Its grouped with the Showa Riders.
RX, Shin, ZO, and J are clasified by Toei as Showa Riders, there's not much to argue about.
Toei-wise, Showa, since their official "series" for the Heisei started with Kuuga, since the 3 KRs are from movies which was still based from their old production structure during the Showa-era.
