Rummaging around for tropes not on the sandbox page that are candidates for JapaneseTropes (aside from the UsefulNotes ones):
* VisualKei - often crops up as a trope (musicians or wannabe musicians or just aping the style)
* BifauxnenAndLadette

Listed on AnimeSettings (which is apparently ''common'' settings, not ''anime-specific'' settings):
* ElevatorSchool
* TokyoIsTheCenterOfTheUniverse
* TokyoTower

And potentially some of the tropes on AnimeHair:
* IdiotHair
* PrincessCurls

Took a look at the {{UsefulNotes.Japan}} page; there's a whole bunch of different kinds of pages.

There's historical/background information about people/ places/events in Japan (marked UN according to my impression)

There's "notes about Japanese culture that would be matter-of-fact in Japan but causes foreigners to go ''huh?''" (marked "trivia" according to my impression).

There's stuff that is used in Japan as a trope, particularly Japanese cultural stuff that gets exaggerated or portrayed inaccurately in fiction for plot purposes or to make it more interesting (marked "trope" according to my impression)

And a lot of them overlap.

I'd suggest moving the ones that are clearly tropes onto index pages like JapaneseTropes or StockJapaneseCharacters, etc, and linking the UN/Japan page to the indexes as SeeAlso; that would clean things up immensely. There might also be value in a "famous Japanese people" index.
