Keep the broth
After the first noodles, another cooked portion goes into the remaining soup. The Ramen Museum explicitly distinguishes noodle seconds from a soup refill. The amount of broth left therefore matters.
JAPANESE CULTURE, EXPLAINED
Kaedama: another portion of noodles for the same soup
替え玉
Kaedama is an extra serving of ramen noodles added to the broth already in your bowl. It is an ordering practice rather than a separate soup flavour or a second complete bowl of ramen.
01
Refills and larger portions
Kaedama and a larger initial serving
Ōmori supplies a larger initial portion; kaedama adds noodles later to the existing broth. Menus set the options: Ippudo’s summer 2025 thick-noodle tsukemen announcement excluded noodle refills and offered a large portion instead. Extra toppings and another complete bowl are different orders again.
| Order | What changes |
|---|---|
| Kaedama | Extra noodles, existing broth |
| Ōmori | More noodles in the initial serving |
| Toppings | Selected topping |
| Another bowl | A complete new serving |
One operator’s ordering system
Ichiran describes placing a kaedama plate on the button at the back of the counter; a sound signals staff to collect it. The second serving can have a different firmness. This is that chain’s system, not a procedure shared by every ramen shop.
02
The Nagahama account
A Nagahama connection
Fukuoka’s tourism agency links Nagahama’s very thin noodles to busy fish-market workers: they cooked quickly for rapid service, but softened readily in soup. Later portions offered an alternative to serving more noodles at once. This is the agency’s account of the practice’s development. The agency identifies Ganso Nagahamaya, founded in 1952, as a key named shop in this history. It also describes thin noodles and kaedama spreading from Nagahama into the broader Hakata style. These are linked practices with a local history, rather than requirements for every bowl called Hakata ramen; the same account cautions that regional boundaries and origin stories vary.
Check your understanding
Why keep some broth when planning kaedama?
The extra noodles go into the broth already in the bowl.
Which two options differ in when the extra noodles arrive?
Ōmori enlarges the initial portion; kaedama comes later, where the menu offers it.
