Kewpie Mayonnaise
What it is
Japan's beloved mayonnaise — richer, tangier, and more umami than Western mayo, in its signature soft squeeze bottle with a red baby (kewpie doll) logo and a star-shaped nozzle. Considered irreplaceable in Japanese cooking.
How it's made
Kewpie uses egg yolks only (not whole eggs), giving a richer, deeper-yellow, silkier emulsion; it's seasoned with rice vinegar (and apple/malt vinegar) rather than distilled vinegar, and includes MSG, which together produce its distinctive tangy-umami depth. The result is creamier and more flavorful than typical Western mayo.
Flavor profile
Rich and custardy from the yolk-only base, with a brighter, rounder tang from rice vinegar and a pronounced umami savoriness; noticeably more flavorful and less flat than Hellmann's-style mayo.
Culinary uses
Drizzled over okonomiyaki and takoyaki (with the brown sauces), in onigiri fillings, tuna and egg sandwiches (tamago sando), potato salad, on grilled corn, and as a dip; squeezed in decorative lines. Its tang and richness are why Japanese cooks consider it non-interchangeable. Pairs with okonomiyaki, fried foods, seafood, rice, corn.
Regional variations
Japanese Kewpie (since 1925) is the icon; the export version sometimes omits MSG and differs slightly from the domestic recipe, which devotees say isn't quite the same. Korean and other Asian rich mayos follow a similar yolk-and-rice-vinegar template.
Cultural & historical context
Founder Toichiro Nakashima encountered mayonnaise in the US and adapted it for Japan with extra egg yolk to boost nutrition and richness, launching Kewpie in 1925. It became deeply embedded in yōshoku and street-food culture, to the point that "Japanese mayo" is now its own recognized category worldwide — a case of an imported condiment so thoroughly reinvented it became distinctly national.
