If you think that authentic miso soup should have only three solid ingredients — tofu, wakame and scallions — you might be in for a surprise. There are so many other ingredients that can be added to miso soup. Tofu is not even always a must.

Connie’s Notes
Tonjiru (butajiru) is a variant of Japanese miso soup. Diluted miso paste is added to the pot after simmering small pieces of pork and vegetables in dashi.
Miso soup with pork and vegetables is either tonjiru (its name in Eastern Japan) of butajiru (the name it goes by in Hokkaido and Western Japan. Why the two names? It’s a translation thing. There is only one character in the Japanese writing system and that character can be pronounced either as “buta” or “ton”.
So, tonjiru / butajiru is cooked with pork and a variety of vegetables. There is no hard rules as to what vegetables can accompany the pork. Radish (daikon), carrot, seaweed and scallions are common but starchy vegetables like sweet potatoes can be added too. Mushrooms are often thrown in too.
