Mizukakena-zuke水かけ菜の漬物
Mizukakena is a leaf green grown in winter paddies kept warm by Fuji spring water. The washed greens are rubbed with salt, layered under a weight, turned top to bottom the next day and eaten three or four days after salting. It is a short salt pickle; no source read says how far it ferments.

Mizukakena is a leaf green grown in winter paddies kept warm by Fuji spring water. The washed greens are rubbed with salt, layered under a weight, turned top to bottom the next day and eaten three or four days after salting. It is a short salt pickle; no source read says how far it ferments. Made in 5 steps over 4 days – 5 days. The longest step, eat once ready, takes 3–4 days (MAFF うちの郷土料理 (Our Regional Cuisines) 2026). Salt is 3–4 % (MAFF うちの郷土料理 (Our Regional Cuisines) 2026).
For lightly salted pickles eaten after a short time (asazuke), Japan's health ministry says there is no heating or fermenting step that fully sterilises the product, so raw leaves are kept at 10 °C or below, washed under running drinking water and disinfected, and the product is kept at 10 °C or below [mhlw-asazuke]. The notice does not name mizukakena-zuke.
Mizukakena is said to have been grown from seed that the head of Atano, Kitagō village (now Oyama), brought from Echigo (Niigata) in 1886. Women from Echigo, who came with the workers building the Tōkaidō line (now the JR Gotemba line) in the mid-Meiji era, are said to have first pickled it.
