Shishitō (ししとう / 獅子唐) is a mild Japanese pepper cultivar (Capsicum annuum 'Shishito') with broad culinary applications: tempura ingredient (defining category), yakitori and grilled-skewer ingredient, sauteed and simmered preparations, and modern snack-format roasted shishito (trending globally as upscale tapas-style snacks since approximately 2010). Kochi and Wakayama lead domestic production, with year-round greenhouse availability and summer outdoor peak. A distinctive consumer-experience element: approximately 1 in 10-15 peppers is unexpectedly hot due to environmental stress during cultivation, sometimes positioned as 'shishito roulette' — adding interest to the cultivar's profile. Global recognition has grown substantially since 2010 with shishito appearing in Western tapas, Korean BBQ, and contemporary cuisine.

What it is

Shishitō is a Capsicum annuum cultivar bred for mild flavor, small size (5-7cm long), and characteristic wrinkled appearance. The name 'shishi-tō' (lion pepper) refers to the head shape resembling a lion's head.

Production: Kochi (the volume leader), Wakayama, and other warm-climate Japanese regions. Year-round greenhouse availability with summer outdoor peak.

The 'unexpectedly hot' phenomenon: approximately 1 in 10-15 peppers becomes hot due to environmental stress (heat, water stress) during cultivation. While not predictable, this has become a known consumer-experience element.
