>that modern Japanese culture so heavily defined by its interactions with the West
It's maybe a small detail: The hero picture of the article shows Miyazaki in front of his atelier near Studio Ghibli with an old German mailbox ("Postkasten") next to him.
It should be noted that Japan has a very special and long history with German Countries. Germans brought modern western medical knowledge to Japan in the 17th. Century, influencing the country to the point that the language used in the medical sector was German (AFAIK still is today to some degree). In the 19th. Century when Japan was forced to open itself to the world, Japan had a friendship and treaty with the German state Prussia, which helped to modernize Japans industry and society. The whole education-system at the time was basically imported from there, to the point that the iconic look of Japanese pupils today are going back to Prussia.
That mailbox is in similar style, it's very old and the design is so classic that the word on it is not even common any more today.
You'll also notice that the manufacturer, Caproni, is the same guy who shows up in all of the dream sequences in The Wind Rises. Also, IIRC, the engine in Porco Rosso's plane is from a Ghibli.
