Kanzuke (twice cold-wind-dried daikon)寒漬け
Kanzuke is daikon dried twice in the cold winter wind, with a salting in between. The whole daikon hangs until it bends, is salted under a stone for about 20 days, then hangs again for one to two months until amber. The dried daikon is then soaked, sliced and steeped for a few days in soy sauce, sugar, mirin and vinegar.

At a glance
Kanzuke is daikon dried twice in the cold winter wind, with a salting in between. The whole daikon hangs until it bends, is salted under a stone for about 20 days, then hangs again for one to two months until amber. The dried daikon is then soaked, sliced and steeped for a few days in soy sauce, sugar, mirin and vinegar. Made in 5 steps over 2 months – 3.2 months. The longest step, hang again until amber, takes 30 days – 2 months (Ministry of Agriculture 2026). Salt is 5–6 % (Ministry of Agriculture 2026).
Kanzuke dries the daikon twice in the cold wind, before and after a salting, and is only then marinated in soy sauce. Most dried-daikon pickles, such as takuan, are dried once and then pickled in bran or salt.
School and home versionsGinger, kombu or yuzu-koshō are added to the marinade; a local junior high school dries its daikon in January and marinates it in February.
Safety
The salted, twice-dried daikon keeps well; once marinated, MAFF suggests freezing to keep its flavour and colour.
Daikon hanging from the eaves were a winter sight of Ashikita and Minamata from late November to about March. Bamboo, plentiful in the area, gives the skewers. Fewer people dry daikon at home now, and dried daikon is sold for families to marinate themselves.
