Soramame (Broad / Fava Beans)

Soramame is Vicia faba, the broad bean / fava bean of Mediterranean and Asian origin. The bean is large (1-3cm), kidney-shaped, with a distinctive black hilum (the 'eye'). The pod is fuzzy on the outside and lined with white cushion-like padding. The mature pod faces upward toward the sky — hence the Japanese name 'sora-mame' (sky bean).

Nutritionally, fresh sora-mame per 100g provides 102 kcal, 10.9g protein, 0.2g fat, 15.5g carbohydrates with 2.6g dietary fiber. Dry mature beans are more concentrated: 348 kcal, 26.0g protein per 100g. Mineral content includes K 1100mg, Mg 90mg, Ca 100mg, Fe 5.7mg per 100g (dry basis).

Production: Kagoshima (Ibusuki) is Japan's volume-leading fresh sora-mame producer, with Chiba and Ehime providing additional supply. Spring seasonal harvest (April-June) is the established retail and foodservice peak. Dry mature sora-mame is largely Chinese-imported.

Health note: fava beans contain vicine and convicine, which can cause hemolytic anemia (favism) in individuals with G6PD deficiency. The condition is rare in Japanese populations (more common in Mediterranean and West African populations), but is a documented health concern globally.

Premium fresh spring vegetable retail — sora-mame in pod is a major spring seasonal retail item (April-June peak). Grilled, boiled, simmered, and tempura preparations are common.

Edamame-position spring snack — boiled sora-mame with salt is an early-summer izakaya and home consumption staple, parallel to edamame positioning but earlier in the season.

Sora-mame chips and snacks — Calbee, Tohato, and many regional brands produce roasted and fried sora-mame snacks. Japanese-style 'sora-mame chips' (with skin removed) and 'iri-soramame' (whole roasted) are established retail categories.

Nimame and simmered preparations — dry soramame is used in traditional Japanese sweet-simmered preparations.

Confectionery and flour applications — sora-mame paste and flour are used in some traditional Japanese confectionery.

For OEM: fresh soramame in pod retail (Kagoshima Ibusuki origin, spring seasonal supply), frozen sora-mame retail packs, sora-mame chips and snacks production OEM (volume retail category), nimame ready-to-eat retail, and dry soramame ingredient supply.

Standard agricultural product labeling. Origin disclosure (Kagoshima Ibusuki, Chiba, Ehime domestic vs Chinese imported) is significant.

Spring seasonal positioning: fresh soramame is heavily concentrated in April-June retail and foodservice.

Soramame is not a designated allergen.

Favism food safety: while rare in Japanese populations, voluntary consumer information about G6PD deficiency consideration is sometimes included on labels.
