Chiba Reiko, who plays Mei, later on became a yoga instructor. You can see how she looked in 1995 because she did a guest appearance in one of the Hibiki commercials. For a while, there was a rumor that she was the daughter of Sonny Chiba, but this was proven false and IMDB has removed this information from her page since then. (Sonny Chiba does have children, but they took on his real family name, Maeda)
Looking at her Japanese wiki page, apparently she had never met a man as scary as Director Toujou Shouhei during the filming of ZyuRanger. In an unverified pargraph, it says the director said things like, "Mei, you idiot! Why don't you go die?!" "You sure are crying a lot! Stop it! Change in scenario! Switch heroines!" "I've never seen such an awful female warrior before!" which would cause her to cry everyday. But he strictly taught her manners and courtesy and in the end she was grateful to him. The last thing that it says is that they both came from Fukushima, so the director complained that she had a bit of an accent. Secretly she thought, "The director also has that accent..."
Like I said, I didn't see a source for this story, so who knows how true it is. Take it with a grain of salt
