Drugs are bad, m'kay. Okay, they aren't that bad. Anything in moderation is good. Well, most things. Anyway, despite the fact most tokusatsu productions are aimed at children, there are sometimes plots involving drugs on the show, or drug use. This can be value dissonance, as in Japan, they are a tiny bit more lax with what they put on TV for kids, and this can cause controversy for some fans. Me: well, they aren't glamorising it.
Oh, and of course alcohol. Most of the notable times we see alcohol in tokusatsu is usually in a drunken boxing episode. (or in Shinkenger, in which Doukouku lives on that stuff). Two examples can be in Fiveman and in Dekaranger. In Fiveman, the Zone convert all of Earth's water supply to alcohol, causing people to get drunk. And not just adults, but children. You see children in drunken stupors. Oh, and not just humans. Drunken cars. Cars are drunk which puts a new meaning on drunken driving. So Remi falls into the water when fighting Zaza and then gets drunk herself, but then uses it to her advantage, and drinks even more, and defeats the MOW by using Drunken Kung Fu. She then has a big hangover. Umeko purposely gets herself drunk and uses the same Drunken Kung Fu techniques to counter an Alienizer's ability. She then has Doggie drive her Pat Signer, instead of her, and Doggie explains to the audience that drinking while driving is bad. It's especially bad if you're driving a giant robot!
There are other examples about alcohol, but I'm not going to list them all!
So, is it wrong to include drugs in a series aimed for children? Tokusatsu is aimed at teenagers and adults as well, through different methods. So not just kids watch the show. And they aren't portrayed positively or glamorized. Nor are they used that often, maybe once per series. But they still cause controversy, as they would in any form of media.
