Dago is the Kumamoto word for dango, dumpling, so the dish is also called dango-jiru. Wheat flour, or sometimes rice flour, is kneaded with water and left to rest, then stretched out by hand and torn directly into the pot.

How thick the pieces end up is a matter of whose kitchen you are in. Some people pull them nearly transparent, others leave them thick enough to hold the print of a thumb. Whatever vegetables the season provides go in with them, taro and burdock among the usual ones, and it is seasoned with miso or with soy sauce.

The reasons given for its persistence are all practical ones. It is quick to make, it carries real nutrition, and it sits in the stomach, so it was what got eaten in the gaps during agricultural work when nobody had time to prepare anything properly.

Within Kumamoto there are a great many versions of it. Sweet potato worked into the dumpling is common. There is ikinari dago-jiru in Kumamoto city, ohimesan dango-jiru up in the Kamoto and Kikuchi districts, anmochi dago-jiru over in Koshi. Each has its own name, its own texture, its own filling. What that means in practice is that a single word covers a large number of genuinely different dishes, and everyone using it assumes their own version is the one being meant.
