What happened to the dominant Japanese heavyweights?

Randomly rewatching WK10 now and have to remark on just the pure quality of the domestic talent on it. Say what you want about AEW and WWE signing western talent away, but damn NJPW had Okada, Tanahashi, Nakamura, Shibata, Ishii, Naito and Goto just from the big boys on that one show

I have read others say that it was a known concern even when Finlay's class were Young Lions that there's no obvious next great Japanese heavy but why are guys like THAT not coming out of the Noge dojo anymore? Guys that regularly put on 5 star matches. Guys you could randomly match up against any of each other and you knew it'd be a classic. Takeshita is as good as any of them as a worker but he's not a Noge dojo guy. Ibushi was the same story before him. What's the deal with the 15 years or whatever since Okada came up of no elite talent?
