Japanese Garden Herbs: Myoga, Kinome, Ao-Jiso Shiso, and Their Precise Culinary Applications

Japan — myoga: nationwide but strongest in western Japan; ao-jiso: nationwide cultivation; both are integral to the seasonal Japanese herb calendar

The Japanese kitchen garden produces a collection of herbs and aromatic plants — myoga, kinome, ao-jiso (green shiso), and the broader herb vocabulary — that function as seasonal flavour accents with precise cultural and technical applications that are often misunderstood in non-Japanese kitchens. Each herb occupies a specific position in the Japanese flavour vocabulary and has applications that are not interchangeable. Myōga (茗荷, Japanese ginger bud, Zingiber mioga) is the flowering bud of a non-rhizome-producing ginger plant, harvested before the flower opens (July–October). The flavour is floral-ginger with mild heat, significantly more delicate than regular ginger (shoga), and its texture is crisp from the tightly packed bud structure. Myoga is used exclusively raw or very briefly cooked: sliced into thin rounds as a garnish for cold soba, miso soup, tamagoyaki, and sashimi. The slightly pungent floral heat of myoga is a summer and early autumn marker — its appearance in a bowl signals the high summer season as precisely as matsutake signals autumn. Ao-jiso (青紫蘇, green perilla, Perilla frutescens var. crispa) is one of Japan's most versatile aromatic herbs, with a flavour profile combining fresh mint, anise, basil, and cilantro in complex proportion. Ao-jiso is used raw as a large leaf wrap for hand-rolled sushi, finely chiffonade as a garnish for sashimi and cold soba, and fried whole as a tempura (shiso tempura — one bite is the entirety of the preparation). Red shiso (aka-jiso) is used for colouring umeboshi and shiso-vinegar pickles but rarely eaten raw. The shiso seed (hojiso) and shiso flower (hanajiso) are separate garnish products used in kaiseki for textural and aromatic variation at the micro-scale.

Myoga: floral-ginger, mild heat, crisp texture; Ao-jiso: mint-anise-basil-cilantro complex, intense and immediate aromatic; both: seasonal markers that contribute flavour entirely through aroma rather than sustained taste
