Description

The Japanese long white onion (negi, Allium fistulosum) is arguably the single most ubiquitous seasoning vegetable in Japanese cooking—appearing in every cuisine category from high kaiseki to convenience store nikuman. Unlike Western onions (Allium cepa), negi is a bunching onion with no central bulb; its usable portion is the entire length from white shaft through dark green tops, each section having distinct culinary properties. The thick white shaft (shiro-negi) is the mildest, sweetest part—appropriate for long-cooked preparations (hot pot, miso soup), braising with meat, and the classic negi-toro (fatty tuna with minced negi). The light green shoulder has intermediate pungency—used in yakitori negi-ma (chicken and negi skewer). The dark green tops (ao-negi) are the most pungent and are used in small quantities as a fresh garnish. Regional negi varieties create further complexity: Kujo negi (Kyoto) has soft, sweet dark green tops used differently from the white shaft; Hiroo negi (Saitama) has an exceptionally thick white shaft favored for hot pot. The preparation technique matters—finely julienned negi (ito-negi, thread negi) creates a different flavor release than rough chopping, and the traditional seirogan-giri (diagonal cut at a constant 45°) creates maximum surface area for flavor development in soups.

The Thread

—Both cuisines have a long, mild member of the allium family as a foundational aromatic that appears across all cuisine registers from home cooking to haute cuisine French

—Both East Asian cuisines use the full length of the allium plant with different applications for white shaft and green tops—a whole-vegetable philosophy Chinese

—Both cultures have elevated a specific allium variety to the status of national culinary symbol, with the vegetable appearing in the most formal and everyday preparations simultaneously Welsh

Flavour Context

White shaft: mild sweet onion depth; gentle sulphur; very long cooking produces sweet caramelisation; ao-negi: pungent fresh allium; charred negi: complex smoky sweetness; thread-cut negi in cold water: fresh, mild, slightly sweet with aromatic punch
