Introduction to Shiso: Botanical Roots and Cultural Heritage
n
Shiso (Perilla frutescens var. crispa) is an annual herb in the mint family—Lamiaceae—native to East Asia and widely cultivated in Japan, China, Korea, and Vietnam. In Japan, shiso is considered an essential culinary herb and is known by names such as ”aojiso” (green shiso) for its green variety, and ”akajiso” (red shiso) for its reddish-purple type. Westerners sometimes refer to it as ”beefsteak plant” due to its deep red leaves, though this term can cause confusion with other unrelated plants.
n
While shiso is well-known in Japanese kitchens, its cousin—Korean perilla, or kkaennip—is prominent in Korean cuisine, featuring slightly thicker, broader leaves with a more pronounced anise-like flavor.

Varieties of Shiso: Green, Red, and Beyond
n
Shiso exists in several distinctive forms, differentiated by leaf color, texture, and culinary applications:
n
- n
- Green Shiso (Aojiso or Oba): Most common in Japanese cooking, these leaves are bright green, saw-toothed, and have a crisp texture. Their flavor is bold, fresh, and slightly spicy, with minty, basil, and citrus notes.
- Red Shiso (Akajiso): Reddish-purple leaves with milder flavor, often used for pickling (especially in coloring umeboshi plums), beverages, desserts, and syrups. The pigments in red shiso are anthocyanins, which contribute to its color and antioxidant properties.
- Bicolor Shiso: Leaves that are green on the top and purple underneath, offering both flavor profiles and visual appeal.
- Ruffled or Frilled Shiso: Some cultivars have deeply ruffled leaves, prized for their ornamental look and particularly popular in Japanese plating.
