I haven't. Would you like the save? Alternatively, it could be X turns after Takuga is conquered, or X turns after Izumo is conquered, or something like that. I can only tell you that after just passing the turn without regard up until Turn 29, where the only (relevant) scene that triggered was the Exterminator one, only then did the 'Ask Ryouma about Motonari event' appeared.

It did eventually appear--on Turn 29. https://i.imgur.com/CBPQ53F.jpg

Worth noting I went Tanegashima -> Akashi -> Takuga -> Mouri. I already conquered Takuga by the time I declared war on Mouri.
