Japanese Tōgarashi Varieties and Shichimi Composition

Japan — tōgarashi introduced via Korea in the 16th century (Nanban trade); shichimi tōgarashi blend formalised 17th century Edo period; Yagenbori (Tokyo, 1625) is the oldest commercial producer still operating

Tōgarashi (唐辛子 — Japanese chilli) encompasses a range of chilli pepper varieties and the iconic spice blend built around them. Key chilli forms: (1) Shishitō (獅子唐) — small, thin-walled mild green peppers with occasional hot fruits (1 in 10); almost always cooked whole in a dry or oil-blistered preparation (yakimono or agemono); (2) Kōchi tōgarashi — small, fiery Japanese chillies grown in Kochi Prefecture; dried and powdered as ichimi tōgarashi (single-ingredient chilli powder); (3) Yagura tōgarashi — whole dried chillies used in tsukemono brine and nabe to add subtle heat. Shichimi tōgarashi (七味唐辛子 — 'seven flavour chilli') is Japan's most complex spice blend, made from: red chilli (tōgarashi), sanshō pepper, black and white sesame seeds, dried yuzu or orange peel, hemp seeds (or poppy seeds), nori (or aonori), and ginger powder. Regional shichimi varies: Yagenbori (Tokyo) tends to be more aromatic; Shichimiya (Kyoto) more refined with yuzu emphasis; Yawataya Isogoro (Nagano) more pungent. Shichimi is used as a finishing spice on ramen, gyudon, udon, soba, and karaage.

Shichimi: complex heat with citrus, tingle, and aromatic depth from the seven-component system; no single note dominates; ichimi: pure heat with subtle chilli aroma; shishitō: gentle, slightly sweet green pepper with occasional heat surprise
