Why a donabe does nothing on an induction hob
A donabe is made for a flame. On an induction hob most of them do not get warm at all — and that is physics, not a defect. It is the one incompatibility here that no amount of care or technique gets around, because it is decided before the pot is even lit.

What the hob is actually doing
An induction hob heats by inducing an electric current in the metal base of the pan; the pan itself becomes the heater. It needs ferromagnetic metal — cast iron, or certain stainless steels — touching the surface. Fired clay conducts no such current, so no heat is produced in it. Hobs with pan detection will not power a zone they cannot detect a suitable pan on.
This is why the answer is not “turn it up” or “use a different setting”. There is no setting: the pot is not the wrong shape or the wrong size for the hob, it is the wrong material for the method. A gas flame or a radiant element heats the pot from outside; induction asks the pot to heat itself, and clay cannot.
The version that does work
Induction-ready donabe do exist. Bernal Cutlery’s care page makes room for them explicitly — its warning against electric and induction hobs is prefaced “unless IH specified” — and the Japanese term for them is a common enough search that it autocompletes. The construction is the obvious one: metal bonded into the base so the field has something to act on. What you cannot do is convert an ordinary donabe, and a listing that says only “donabe” is describing the ordinary kind.
Where to look
If you cook on induction, the specification you need is stated on the pot, not inferred from the pictures: look for an explicit induction or IH marking, or a visible metal disc in the base. A listing that says only “donabe”, however traditional the photographs, is describing the flame kind.
There is no shop link on this page. Recommending a pot here would mean recommending one whose base construction we cannot check from a listing — which is the exact failure this page is about. The two care guides below cover the pot once you own it.
