You know what i think, After reading both of your comments I think Toei should focus on the stories for the next super sentai and kamen rider series rather than the silly things bandai comes up with like 'fashion' for example and let them make the story revolving around it
The whole controversy with Kamen Rider Hibiki has made it very clear that Bandai expect to get their money's worth as sponsors. TV shows are expensive to make. They cost tens of thousands of dollars
per episode. If Bandai aren't paying for it, Toei would have to find a massive amount of money to continue making the show on their own (let's make the math simple, $10,000 per episode, 50 episodes, that's half a million dollars!) and unless they could guarantee they'd somehow make their money back they wouldn't even try - they are a business at the end of the day.
And as I said before, it's regular, reliable money. Doing Rider and Sentai allows Toei to make other things that are perhaps less likely to make their money back.
It didn't happen to ultraman and the first kamen rider and super sentai series during the 70's including Black,Kuuga and Garo (though the latter one becomes a cash cow franchise but at least the company cares about the story rather than what toei did with super sentai and kamen rider )
Erm, Ultraman's last series was Ginga/Ginga S, which is all about collecting litle vinyl figures of the characters. The upcoming series is all about trading cards. Garo doesn't even try to aim for the Rider/Sentai audience - it airs at 1am and is marketed at existing (grown up) toku fans. Even then it continues mainly because it's creator isn't afraid to use the clout he's built up over his career (and even then after the first series ended it took him three years to convince anyone to let him continue with it).
70s Rider had much larger ratings and even then it lasted five years and died...came back for two years and died...came back for another two years and died... Let's not get started on the 90s Riders that tried to appeal to the grown-up fans of the original and failed hard.
i mean this process is similar to what Takara Tomy' did with their product line Tomica toy cars with their tokusatsu series franchise called Tomica Hero Series
You do realise that the Tomica Hero franchise lasted for just two series? One of the main reasons it died was that it just couldn't compete with Sentai and Rider. I don't think the way forwards for any franchise that has endured for decades is to start mimicking a franchise that they helped killed off.
You know, after the 20th heisei anniversary, do you think this whole collectible gimmicks are still going to be in? I can see that things are getting more compact and mobile. Perhaps toys will be streamline or something.
Sadly not. Japan's birth rate is spiralling ever-downwards, which means if you're locked into selling toys to children you have to squeeze more money out of each one to compensate for there being less of them. It may change however. I think as the age at which children get phones seems to get ever younger, we may eventually see a franchise switch to having their heroes use a phone app to transform, so they can sell that to kids and then charge them for extra DLC.
And i forgot one thing i understand why Joe odagiri won't reprise his role as kuuga because the toei's tokusatsu franchise is acting like a toy commercials nowadays unlike the productions days of kuuga.
I don't think that's ever been a factor. Plus Kuuga had more forms than any other Rider until Double. That's a lot of action figures to sell to kids. Most of them also had their own unique weapon for Bandai to sell as toys.
