It is said that Oden comes from misodengaku, which is tofu or konnyaku boiled in water and seasoned with miso (edamame) and eaten. Later, the Japanese used bonito soup instead of miso, and kanto boiled was allowed to flourish.
The method of preparing Oden varies from place to place in the Kanto region. However, unlike normal nabe dishes, it is easy to prepare and the ingredients can be put into the soup at any time. That's why it's especially popular in winter. In Japan, it can be bought at convenience stores and street stalls.
