Had to drop by. I had a feeling Miyazaki's house would be near the studio and it was, just a few blocks away. After walking past a couple of times (6) I caught a glimpse of a silver haired gentleman inside. There was at Citroen 2CV parked outside. Pretty sure this car featured in his first film Castle of Cagliostro.
I sat on a park bench near the house and did a quick portrait (pictured below with my recently purchased Terada piece) then felt enough like a stalker for one day and headed back to Shinjuku.
