Filming Locations of "Tampopo?"
Have you seen the movie Tampopo? It's a mid-80s Japanese film with three parts, the primary one involving a woman named Tampopo trying to perfect ramen.
I have tried to search which locations in Japan were used as the backdrop, by looking online and asking around Tokyo. It wasn't necessarily filmed in Tokyo, but if you have any ideas/links to provide on the topic, please let me know.
Apparently the model for the Tampopo ramen shop was 佐久信 (Sakushin) in Ogikubo, Tokyo, which no longer exists. Filming was done at 春木屋 (Harukiya) in Karuizawa, which also apparently no longer exists. Both ramen shops served "Ogikubo Ramen", and Harukiya still has shops in Ogikubo and Kichijouji in Tokyo.
