Korean food is popular in Japan, so gochujang, kimchi and rice cakes are in ordinary supermarkets. Only a few items, like perilla leaves, need a Korean shop or a swap.
Most supermarkets have a Korean shelf with gochujang, Dashida beef stock and Korean seaweed. KALDI and Gyomu Super sell gochugaru and Korean glass noodles. Shin-Okubo in Tokyo, Tsuruhashi in Osaka and online shops have everything.
