Oryza Oil & Fat Chemical Co., Ltd.

Rice bran extract is derived from the pericarp and germ fractions of milled Oryza sativa. Long used in Japanese household skincare via togijiru (rice-rinsing water) and nukabukuro (rice-bran poultices). The extract concentrates gamma-oryzanol, ferulic acid, tocopherols, and B-vitamins, and pairs well with other rice-derived materials.

Rice-derived glucosylceramide is a sphingolipid extracted from rice germ or rice bran, used in both ingestible supplements and topical cosmetics. Japanese FFC notifications cite effects on skin moisture retention. Production leverages Japan's rice-milling byproducts, aligning with sustainability positioning.

Matcha is stone-ground tea powder made from shade-grown tencha green tea leaves. Japan's traditional production centers are Uji (Kyoto), Nishio (Aichi), and Shizuoka. Uji matcha is a protected geographical indication (GI). Nishio no Matcha was previously a GI but its registration was withdrawn in February 2020 and it is now protected as a Regional Collective Trademark. Export demand has grown sharply since the 2010s.

Sencha is the most widely consumed Japanese green tea. The extract form is spray-dried or concentrated for use in beverages, supplements, and functional foods. Catechins, L-theanine, caffeine, and chlorophyll are key actives. Several FFC products cite sencha polyphenol or specific catechin content for metabolism claims.

GABA is a non-protein amino acid produced commercially in Japan by lactic-acid bacterial fermentation or chemical synthesis. Japan is a global leader in functional-food applications of GABA, with thousands of FFC notifications citing stress reduction, sleep quality, and blood-pressure support.

Perilla frutescens, known in Japan as shiso (紫蘇), is a herb of the mint family used in Japanese cooking and traditional medicine. The leaves contain rosmarinic acid, perillaldehyde, and anthocyanins (in the red variety). Used in cosmetics for soothing and antioxidant positioning.

Yuzu (Citrus junos) is a Japanese citrus with a distinctive aromatic profile. Kōchi prefecture is Japan's largest producer. The peel yields essential oil dominated by d-limonene, while aqueous extracts carry flavonoids and citric acid. Used in fragrance, bath products, and skin-conditioning toners.

Astaxanthin is a carotenoid pigment produced primarily by microalgae (Haematococcus pluvialis), known for strong antioxidant capacity. Japanese production pioneered by Fuji Chemical Industry and ENEOS uses closed-system microalgae cultivation. Multiple Japanese FFC notifications cite astaxanthin for eye health, skin health, and antioxidant support.

Fucoidan is a sulfated polysaccharide extracted from brown seaweeds, most commonly mozuku (Cladosiphon okamuranus) from Okinawa and kombu (Saccharina japonica) from Hokkaidō. Studied for moisturizing, immune-modulating, and antioxidant positioning. Sold as both a cosmetic ingredient and a functional food supplement.

Standardised beta-1,6-glucan extract from maitake mushroom (Grifola frondosa), originally developed at the Kobe Pharmaceutical University in the 1980s. Niigata is the primary cultivation region (~70% of Japan's maitake by volume). The D-fraction is positioned in immune-support and adjuvant supplement contexts internationally; clinical literature exists for both dietary and oncology-adjuvant settings. Functional foods featuring D-fraction must clear country-specific regulatory pathways (FFC in Japan, NDI in US, etc.).

Cultivated lion's mane mushroom — Japanese cultivation pioneered the indoor-grown commercial supply that now dominates the global supplement market. Functional positioning centers on hericenones and erinacines (terpenoid actives) studied for nerve growth factor (NGF) activity. Niigata, Nagano and Hokkaido producers supply both domestic functional food and substantial exports for the cognitive / nootropic supplement segment. Fruiting body and mycelium fractions have different active profiles and command different pricing.

Tochū-cha (eucommia leaf tea) and the bark are core herbal materials in TCM and Kampo. Modern functional positioning emphasises asperuloside and pinoresinol diglucoside, with FFC notifications in Japan referencing blood-pressure and triglyceride support. Domestic Japanese cultivation is concentrated in Nagano and Yamagata; the leaf-based supply for tea and supplements is largely Japan-domestic, while the bark draws on both Japanese and Chinese sourcing. Increasingly used in caffeine-free RTD beverage applications.

Plant-derived glucosylceramide extracted from konnyaku corm (Amorphophallus konjac). Gunma Prefecture produces over 90% of Japan's konnyaku and is the heartland of konnyaku-ceramide supply for both cosmetic and food-supplement applications. Functions as a barrier-supporting humectant in skincare and as an oral ingredient with FFC (Foods with Function Claims) notifications referencing skin moisture support. Distinct from rice-derived glucosylceramide in lipid profile.

Standardised extract of common (Fagopyrum esculentum) or tartary (F. tataricum) buckwheat, primarily standardised to rutin content. Tartary buckwheat carries 5–10× the rutin of common buckwheat and is the basis of high-end functional food positioning. Hokkaido produces about 50% of Japan's domestic buckwheat by volume; Nagano, Iwate, and Yamagata round out the supply. Used in functional foods for circulatory support, in tartary-buckwheat tea, and as a feedstock for rutin-positioned supplements.

Hot-water extract of cultured shiitake mycelium, distinct from the fruiting body in active-ingredient profile. Japanese R&D has standardised lentinan and LEM (Lentinula Edodes Mycelium extract) preparations since the 1980s for immune-support positioning. Major industrial producers in Mie, Gifu, and Niigata supply both supplement and functional-food markets, with substantial export to North American and European immune-positioned supplement brands. Distinct from shiitake-fruiting-body extracts (which are part of the existing 'shiitake-functional' trend coverage).

Cultivated medicinal mushroom (Agaricus blazei), introduced from Brazil but commercialised in Japan since the 1980s, where the cultivar has been refined and standardised under the local 'himematsutake' trade name. Major Japanese producers operate indoor cultivation in Mie, Niigata, and Hokkaido. Beta-glucan-rich extracts are positioned for immune-support supplementation domestically (FFC notifications exist) and exported substantially to North American and Asian supplement markets. Important historical caveat — early-2000s heavy-metal compliance concerns drove tighter quality standards that responsible producers have long since addressed.

A foundational TCM/Kampo medicinal mushroom (Ganoderma lucidum). Japanese cultivation, primarily in Nagano and Niigata, evolved beyond traditional wild collection into standardised indoor cultivation in the 1970s. Modern Japanese reishi suppliers produce both fruiting-body and spore (hoshi) extracts, with the spore variant carrying premium pricing on the back of triterpene concentration. FFC notifications support immune-support positioning domestically. Substantial export to North American supplement and functional-coffee categories.

Cultivated cordyceps (typically Cordyceps militaris in Japanese commercial cultivation) — distinct from the wild Cordyceps sinensis that historically commanded six-figure pricing in TCM. Japanese cultivation emerged in the 2000s with rice-substrate and silkworm-substrate methodologies. Niigata, Mie, and Tochigi host the principal commercial producers. Standardised cordycepin and adenosine content drives both supplement and increasingly Japanese sake-yeast / koji-cordyceps fusion ingredient positioning. A reference cultivated alternative to wild Tibetan plateau cordyceps for compliance-conscious supplement formulators.

Three-day broccoli sprout — the Japanese-cultivated Brassica oleracea sprout positioned around sulforaphane and glucoraphanin content. Japan's commercial broccoli-sprout industry is dominated by Murakami Farm (Hiroshima), which licensed Johns Hopkins / BroccoSprouts methodology and now operates the world's largest indoor broccoli-sprout production. FFC notifications support liver-protective and antioxidant positioning domestically. Substantial export to North American supplement OEMs as a reference Japanese-processed sulforaphane source. Distinct from existing functional-food entries.

Seeds of red and green perilla (shiso, Perilla frutescens) — a high-omega-3 (alpha-linolenic acid) seed grown in Japan and traditionally pressed for perilla seed oil (shiso-yu). Distinct from the existing 'shiso-extract' (leaf-derived) and 'perilla-seed-oil' (the pressed oil) — this entry is the seed and seed-meal ingredient. Used in functional-food applications (omega-3 fortification, plant-protein blends), as a baking and confectionery ingredient (gomashio-style accents), and as a cosmetic exfoliant. Aichi, Hokkaido, and Niigata anchor the principal cultivation.

Standardised glucomannan polysaccharide extracted from konjac corm — distinct from the 'konnyaku-ceramide' (cosmetic ceramide) entry. Glucomannan is a soluble dietary fibre with FDA-recognised structure-function claims for blood-glucose moderation and weight-management positioning. Gunma's >90% konjac monopoly (existing in konnyaku-ceramide entry) underlies the supply chain. Used in shirataki / konnyaku noodle (Japanese low-calorie alternative), as a dietary supplement, and increasingly in plant-based meat-alternative as a binder. Distinct from existing entries.
