Lots of new interesting stuff comes out and dies or doesn't survive, but it means they do have some constant incubation. The American version of this for comics is basically letting new writers try their hand at a big existing property to see if they're any good, but that means the new ideas are "fun spin on batman" or etc. (And of course the indie scene exists in both to different extents, but the publishers for non DC/Marvel stuff in the US are anemic.)
I hear scholastic is genuinely good, but they have a very specific audience ofc.
When I go out as

I find 20% or so people in the general population in my town recognize who I am right away because they watched either Naruto or Demon Slayer and those are both in my queue so I can understand better what they know about me.
... but it is hard because there is Slayers and Futari Wa Precure and many many anime that have a few 12 epsiode seasons in my queue. And a lot of that is in the "so bad it's good category". One of my guilty pleasures is

which gets really good over time because the crazy overpowered protagonist and his Level 9999 friends almost meet their match and I never would have discovered the light novel and manga if I hadn't been willing to watch a truly atrocious J.C. Staff anime. Only in Japan can some ordinary person write a web novel, get a contract for a light novel, get a manga made, then get an anime, video games, etc. The "media mix" strategy lets their industry market test content with low risk and the anime doesn't even have to be profitable on its own if it convinces 10,000 or so obsessive fans to shell out $150 to buy all the books of the light novel and another $150 to buy the books of the manga.
The cost structure of the US media industry is a lot worse and divides between super-expensive prestige content and a tier of slop. It's all a gatekeeping-industrial complex and no wonder people are pissed about DEI, "woke" and all that because it's a zero sum game. The industry would love to get another J. K. Rowlings and we've probably had 10 of them who never got greenlit because of low risk tolerance.
Is this the origin of that trope? I've seen a couple of anime/manga that use the same story as a jump off point. Character that doesn't know their own strength kicked out of the party for being "weak" only for us to later find out they are one of the strongest/most powerful individuals in the world.
Monkey Magic theme song anyone? https://youtu.be/wddJnq-D3XM?si=J2xAgXoygreTD73w
There are certain elements of Journey to the West found in DB but not even Goku is similar to Wukong. Yes, monkey-like features, extending stick, perhaps a couple of early characters but everything else is not even close. So I don't think it's fair to say that is a rehash.
But comparatively the US and most of the rest of the world is in a media dark age. The US seems to only manage to invent a new good property every decade or so. Everything else is rehashing existing ideas.
I really would like to know what Japan does differently to nurture new properties. It clearly works. It seems South Korea and China are also doing pretty well in that aspect.
