I know Tokyo is a good hop on the Shinkansen, but try finding a specialty shop without standing in Kobe is tough. Although I do remember there are a couple of small specialty coffee shops and roasters in the main downtown area of Kobe. Might wander in and ask if they have a "Coffee drip pot" "KOHI durippo potto".
My Japanese is very poor. That's the best I can do.
