Toraya Confectionery Co., Ltd.

A small red bean central to Japanese wagashi (mochi, dorayaki, anko paste) and increasingly used in cosmetic ingredients for its saponin-rich seed coat. Hokkaido produces ~75% of Japan's azuki by volume; the Tokachi region's 'Erimo' cultivar is the most-consumed variety in industrial wagashi production. Cosmetic-grade azuki seed extract appears in cleansing and exfoliating formulations on the back of saponin and polyphenol content.

Premium large black soybean (kuromame) cultivated in the Tamba region (eastern Hyogo / north-central Kyoto). Distinguished by exceptional bean size (~100 beans per 30g vs typical 70 per 30g) and anthocyanin-rich black seed coat. Used in osechi (New Year) confectionery, kuromame-cha (black-bean tea), and as feedstock for anthocyanin-positioned functional food extracts. Production is GI-protected ('Tamba Kuromame' GI registered with MAFF), with cooperative-controlled volume that drives premium pricing. Distinct from the existing 'kinako' (roasted soybean flour) entry.

Polysaccharide gelling agent derived from red seaweed (Gelidium / Gracilaria), traditionally produced through freeze-drying in the high-altitude winters of Nagano. Kanten has 200+ years of Japanese history as a wagashi (kuzukiri, mizu-yokan) ingredient, and modern Japanese producers Ina Food Industry and Marusan Bussan are global leaders in industrial agar supply. Used in confectionery, plant-based dessert, microbiology media (food-grade and laboratory-grade) and as a high-fibre functional food ingredient for satiety / weight-management positioning.

Premium Japanese chestnut cultivar (Castanea crenata) from the Tamba region (eastern Hyogo, north-central Kyoto). Distinguished by exceptionally large bean size (60-70 g per nut, vs typical 20-25g) and a sweet, dense flesh. Tamba Kuri is GI-protected; the Sasayama / Tamba district has 800+ year heritage as the recognised premium origin. Used in luxury wagashi (kuri-yokan, kuri-manju, marron-glacé), Japanese-style mont blanc, and increasingly in upscale Western fine-dining. Distinct from the existing tochi-no-mi (horse chestnut) entry and the kanten / soybean-based confectionery ingredients.

Premium fine-grain Japanese sugar produced in Kagawa and Tokushima from take-shōba sugarcane via a labour-intensive 'togi' (kneading) refining process. Wasanbon is regarded as the most-refined granulated sugar in Japan and is the foundation of the highest-tier wagashi confectionery (rakugan, higashi). Output is severely limited — fewer than 10 producers maintain the traditional method, and annual volume measures in tonnes (vs millions for industrial sugar). Per-kg pricing is 30-100× refined white sugar.
