JRPGs are whatever "developers" want them to be, it isn't actually a genre. JRPGs are just nebulous(or slang?) term describing a trend in console RPGs from Japan.

But, the issue here is that this is not something which remained unique to RPG's. Structured plots and character development have been co-opted by pretty much every genre in existence now, and it started literally decades ago. Whereas WRPG's have been able to remain somewhat unique in their focus on player choice in character building and character interactions (few games that aren't WRPG's have made attempts at giving players meaningful dialogue and mission choices on the level of games like the original Fallout titles or Mass Effect, and the same is largely true when it comes to building your character as they level up), but the story is not something JRPG's retain a monopoly on.
OK, i am not sure how to tell you this but story wasn't an exclusive feature to JRPGs to begin with. Adventure games were more of story driven genre than JRPGs and offer structured plots, choices, investigation options and visual scenes, here some examples from late 80s to early 90s, "Snatcher", "Policenauts" and "Jesus".

Obviously they're not all turn based given the Tales series existence. They don't all have random encounters looking at Chrono Trigger, FFXII, or Persona 3. They don't all have defined character development as FFV, VII, VIII, XII, and others prove. Maybe story and the cutscene really is the sole defining characteristic which binds them all together?
Again, this isn't true, there are many non-RPGs story driven with many cutscenes sometimes , i mean look at "ninja gaiden".
