Anecdotes of 1 are meaningless other than fun stories to share.
I've never been a Jiro fan though, there are many sushi makers in japan that can be considered artists in their craft, but their cultural impact is mehh at best.
Studio Ghibli, both Miyazaki and Takahata, on the other hand...
What I meant is that sushi is still something that we consider a Japanese thing, we know that masters of sushi are Japanese, Jiro being famous only reinforced that notion.
On the other hand Studio Ghibli forced the western industry of animation to recognize their greateness, we awarded them prizes, and now in the west we make products that look and feel like anime and manga. We do not think of Japanese animation of "something for kids", we treat them like Disney.
Comic conventions are full of cosplayers dressed as manga/anime heroes.
Youngsters make meme based on manga, American studios make live actions and animation shows of anime and manga.
It's been a complete game changer, either we like it or not.
If I created something and I wanted that thing to die with me, the love for my children wouldn't in any way stop me.
Legacy and honor are much more important than nepotism for some.
Also, he's saving Goro from being "the son of Miyazaki that was never good as the father" forever.
He's Goro. He's a different person. He made his own choices regardless of who the father is and owes him nothing.
That's a gift if you ask me.
