Shiso / Perilla (Green vs. Red, Japanese vs. Korean)
What it is
Leaves of Perilla frutescens, a mint-family herb, in several culturally distinct forms: **Japanese green shiso (aojiso/ooba) — flat, jagged-edged, bright green; Japanese red shiso (akajiso) — purple-red, frillier, used for color and pickling; and Korean perilla (kkaennip)** — larger, rounder, flatter leaves of a different cultivar (P. frutescens var. frutescens) with a distinct flavor. These are not interchangeable across cuisines.
How it's made
Grown as an annual herb; leaves picked fresh. Green and red shiso are different cultivars used for different jobs; red shiso's purple anthocyanins are exploited to dye and flavor umeboshi and pickles. Korean perilla is a separate, larger-leaved cultivar with its own seeds (toasted/ground into deulkkae seed powder and oil). Shiso seeds, sprouts (mejiso), and flower buds (hojiso) are garnishes too.
Flavor profile
Green shiso: bright, herbaceous, minty-basil with anise, cinnamon, and citrus notes — fresh and complex. Red shiso: earthier, more medicinal, with the same family aroma plus a pickle-y depth. Korean perilla: nuttier, earthier, and more robust, with a less minty, more "sesame-anise" character — a noticeably different flavor from Japanese shiso despite the shared species.
Culinary uses
Green shiso: wrapped around or under sashimi and tempura, shredded into rice and salads, in somen and as a sushi garnish. Red shiso: colors and flavors umeboshi and shibazuke pickles, and the summer drink shiso juice. Korean perilla: a wrap (ssam) for grilled meat, pickled in soy (kkaennip jangajji), in kimchi and stews; perilla seeds/oil season many Korean dishes. Pairs with raw fish, rice, plum, soy, garlic, and grilled meat.
Regional variations
Japan distinguishes green vs red shiso by use (fresh garnish vs pickling/color). Korea centers on the larger perilla leaf (ssam, pickles) and perilla seed/oil. Vietnamese cooking uses its own perilla (tía tô, often bicolor green/purple) as a table herb. Same genus, three distinct culinary identities.
Cultural & historical context
Native to East Asia and cultivated for over a thousand years, perilla split into culturally specific lineages: the Japanese shiso of garnish and pickle, the Korean kkaennip of wraps and seed oil, and the Vietnamese tía tô of fresh herb platters. It's a vivid case study in how one plant becomes several "different" ingredients across neighboring cultures.
Substitution & sourcing — Don't swap Korean perilla for Japanese shiso or vice versa — the flavor and leaf size are wrong for the dish (perilla overwhelms delicate sashimi; shiso is too small and minty for ssam). Buy green shiso and red shiso at Japanese groceries (red is seasonal, summer, for pickling); Korean perilla (kkaennip) at Korean groceries. Choose unblemished, fragrant leaves; both are perishable — use within days.
