Do shops like these mostly inherited? I'm also aware of Japan's adult adoptions. Is there pressure on the next gen. to take over the family business? I would think yes.

In my mind, just imagining operating for a Millennium, these institutions are more temples than businesses. Brings tears to my eyes just thinking about it. Thankfully the practice is not very widespread as I could easily have found myself taking care of a breakfast place by a moderately busy highway in Southern India.
