I don't think that's been the case for at least the past 10 or so yrs (and some Toyota platforms used just b/f TNGA dated back to the 90s, IIRC).
Camry chassis dated back to 2002, heavily reworked around 2006. The previous platform dated back to the 80s.
4runner's Prado frame dates back to around 2002 and is still around and kicking. The tacoma is an open frame rail variation of this (knowledge benefit of having one of each in the driveway ;)) Before that the international/hilux chassis dated back to the 80s.
Corolla chassis was new for 2013
That covers most of it. Close to your point, they almost the 90s indeed and before that they dated back to the 80s.
Can't argue with the success garnered across the lineup and general longevity.
Honda goes full redesign for each generation, and the result is much more appealing products (for the middle aged dad-bellies of C&D) but longevity may not always be the best but its still pretty good.
