I also posted this photo over on
r/kamenrider and this is what Redditor ukiyoe had to say:
"This is Kamen Norida, a regular skit by the Tunnels that was popular in the late 80s through the early 90s. They made this parody without consent from the creators, so home video versions have never surfaced.
Also, one of the big reasons for why the Kamen Rider series was gone for 10 years after Kamen Rider Black RX is blamed on this parody, as the producer at the time felt insulted to work on something that people would poke fun and laugh at. At the same time, Ishinomori Shotaro also gave approval of the show.
So while funny, it has a bitter-sweet history with Kamen Rider"
They also included a couple of links to Japanese wiki pages that I have not bothered to translate and read yet, but here they be.
This &
That &
Something else &
One other thing
Interesting, all the same.
(and sorry about posting in the wrong place, wasn't too sure where to dump this)
