Japan — traditionally grown in Kyoto (one of many kyo yasai), now cultivated nationally
Mizuna (水菜, water vegetable, Brassica rapa var. nipposinica) is a Japanese leafy green with feathery, serrated leaves and crisp white stems, grown in flooded fields (the 'water' in its name). Mild, slightly peppery flavor positions it between spinach and arugula — far less bitter than mature arugula, with a pleasant crunch. Mizuna's main applications: Japanese hot pot (especially shabu-shabu), salads, alongside grilled fish, in soba and udon as garnish. It wilts very quickly when hot — ideally added at the very last second to hot preparations. Baby mizuna is standard in Japanese restaurant salads; mature mizuna goes into nabe hot pots.

{"Wilts immediately in heat — add only in final 30 seconds of hot preparations","Baby mizuna: salad applications; mature mizuna: hot pot and cooked applications","Feathery leaves hold dressings well without becoming soggy quickly","Natural water content is high — salt-dress salads just before serving","Pairs particularly well with ponzu, sesame dressing, and citrus vinaigrettes","Available year-round but peak flavor in cool season (autumn-winter)"}
{"Mizuna and citrus winter salad: mizuna + mandarin segments + sesame dressing","Mizuna with karaage: fresh mizuna beneath fried chicken provides crisp foil to richness","Mizuna garnish for ramen: float on finished bowl for color and slight peppery freshness","Pressed mizuna salad: salt 5 minutes, rinse, squeeze, dress — intensifies flavor","Mizuna and bacon: quick hot pan with good bacon fat — wilted greens in seconds"}
{"Adding mizuna too early to hot pot — 30 seconds maximum before it dissolves","Heavy dressing that drowns the delicate leaves","Washing and not drying thoroughly — waterlogged mizuna becomes unpleasant"}
