Beverage ingredients

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.

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 Nishio no Matcha was previously a GI but its registration was withdrawn in February 2020 and it is now protected as a Regional Collective Trademark.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.

Hojicha is a Japanese green tea that has been roasted at high temperature, producing a distinctive toasty, low-astringency, low-caffeine beverage. The powdered form is used in ice cream, baked goods, specialty lattes, and confectionery. Export demand has grown as a caffeine-lower alternative to matcha.

Mugicha is a Japanese roasted barley tea, naturally caffeine-free and served cold in summer as a household staple. Export applications include children's beverage ranges and caffeine-free functional beverage lines. Note: mugicha contains barley gluten.

Amazake is a traditional Japanese sweet beverage made by fermenting rice with rice koji. Koji enzymes convert rice starch to glucose, producing a naturally sweet, non-alcoholic drink. A separate variant made from sake lees contains low alcohol. Hakkaisan Brewery's 'Kōji dake de tsukutta Amasake' (FFC notification I290) is Japan's first koji-based beverage with dual functional claims via A. oryzae HJ1 strain and koji-derived glucosylceramide. Modern positioning includes 'drinking IV drip' (nomu tenteki) health-food claims.

Sake extract is a concentrated preparation from Japanese rice wine, typically aqueous or hydro-alcoholic extraction capturing amino acids, peptides, and flavor actives. Cosmetic applications use non-alcoholic or low-alcohol fractions for moisturizing and brightening claims; food applications use sake concentrate in seasonings, glazes, and bakery.

A tropical herb native to Okinawa. Research at University of the Ryukyus (Prof. Tawada) demonstrated lifespan extension of 22.6% in nematode studies.

Small citrus native to Ryukyu Islands. Contains the highest nobiletin concentration among citrus fruits.

Amino acid unique to tea (Camellia sinensis). Commercial production led by Taiyo Kagaku's enzymatic method.

Japanese natural spring water from officially designated sources. The Ministry of Environment has selected 100 Famous Waters (1985) and 100 Heisei Period Famous Waters (2008), totalling 200 sites. Japan's first domestic mineral water was Fuji Mineral Water's 'Nihon Evian' (1929).

Japan's most prestigious shaded green tea, distinguished by 20+ days of pre-harvest shading that suppresses catechin synthesis and elevates theanine concentrations 2-3x above sencha. Yame (Fukuoka) and Uji (Kyoto) are the two recognised production regions; Yame produces ~45% of Japan's gyokuro by volume. The deep umami profile and intense green color command per-kg prices 5-10x sencha. Used in premium beverage, supplement, and L-theanine extraction applications.

Blend of green tea (typically bancha or sencha) with toasted brown rice, producing a nutty, mild, low-caffeine profile. Originated as a frugal extender during food shortages and now positioned as a low-caffeine premium daily tea internationally. Toasting protocols vary: light toast retains green-tea character; heavy toast emphasises grain notes. Often blended with matcha (matcha-iri genmaicha) for export markets.

Mid-tier between sencha and gyokuro, produced under 7–10 days of shade cover (vs gyokuro's 20+ days). Mie Prefecture produces over 60% of Japan's kabusecha; Wazuka (Kyoto) and Yame (Fukuoka) also produce. Profile balances sencha's astringency with gyokuro's umami at a fraction of gyokuro's price point. Increasingly used by D2C tea brands targeting buyers who want gyokuro-adjacent quality without the price.

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.

Wild Japanese grape (Vitis coignetiae) native to Tōhoku and Hokkaido. Dramatically smaller and more acidic than European wine grapes, but with anthocyanin and resveratrol concentrations 2–4× higher. Iwate Prefecture is the centre of commercial cultivation and processing — local cooperatives produce yamabudō juice, jelly, wine, and increasingly resveratrol-rich extract concentrates for the international supplement market. Iwate's Kuji and Kunohe districts have GI-protected branding for yamabudō wine.

Deep ocean water sourced 300–600 m below the surface off Cape Muroto in Kōchi. Stable temperature, mineral balance (Mg-rich), and low bacterial load make it a high-grade ingredient for cosmetic moisturisers, mineral beverage, and salt production. Kōchi Prefecture's Muroto and Aki facilities are the largest commercial deep-sea-water sources in Japan; Toyama Bay and Okinawa Kume Island also produce. Branded retail mineral waters and cosmetic moisturising lines have built a multi-decade premium category around the Muroto label specifically.

Light-coloured, mild-flavoured honey from black locust (Robinia pseudoacacia) — the most popular varietal honey in Japan and the dominant Japan-domestic honey type by volume. Akashia honey resists crystallisation longer than most varietals, making it the de-facto retail-shelf honey in Japan. Aichi (Nagoya), Iwate, and Yamagata are the principal Japan-domestic production regions. Japan-domestic honey is heavily premium-priced vs imported Chinese / South American supply; the 'kokusan' (domestic) label is a key consumer trust marker. Distinct from royal jelly and propolis in flavour and supplement positioning.

Mulberry leaf (Morus alba) — a Kampo herbal raw material with FFC notifications referencing post-meal blood-sugar moderation, anchored in the leaf's deoxynojirimycin (DNJ) content. Japanese cultivation, historically tied to the silk industry, has been re-purposed for kuwa-cha (mulberry-leaf tea) and DNJ-standardised supplement extracts. Nagano (the historic silk region), Gunma, and Kumamoto produce commercial supply; small-volume specialty producers in mountainous Tōhoku also contribute. Distinct from the existing mushroom and bamboo-leaf functional entries.

Rare double-fermented post-fermented tea produced exclusively in Otoyo, Kochi Prefecture. Distinguished by its black-stone-like compressed cubes (the 'goishi' name references Go board stones), goishi-cha is one of only a handful of post-fermented teas in the world (alongside Chinese pu-erh and Japan's awa-bancha and ishizuchi-kurocha). Production is controlled by a small Otoyo cooperative — annual output is limited to less than 10 tonnes. Functional positioning targets the lactic-acid bacteria fermentation profile and resulting low-caffeine / high-polyphenol balance. Niche but increasingly sought by tea collectors and natural-fermentation enthusiasts in export markets.

Post-fermented tea (post-fermentation distinct from oxidation) produced in the mountainous Awa region of Tokushima. Like goishi-cha, awa-bancha is a rare lactic-acid-bacteria-fermented tea — one of only a handful in Japan. Production by small Awa-region producers in Naka and Kamikatsu involves boiling fresh leaves, pressing into wooden barrels for fermentation, then sun-drying. The brewed tea is markedly low-caffeine, with a distinctive sour, fruity profile. Niche but with substantial collector and natural-fermentation following internationally; Kamikatsu's 'Zero Waste' branded version commands premium pricing.

Sour citrus (Citrus sphaerocarpa) almost exclusively produced in Oita Prefecture (>95% of national volume). Harvested green for the signature sharp-acid juice; turns yellow in late season. Used as a sashimi accent, in vinegar-and-soy dressings, in clear soups, and increasingly in Western fine-dining as a yuzu-alternative citrus. The juice profile is rounder and less aromatic than yuzu, with higher juice yield per fruit. Distinct from sudachi (smaller, sharper) and yuzu (more aromatic, lower yield).

Small green sour citrus (Citrus sudachi) produced in Tokushima Prefecture (>95% of national volume). Distinguished from kabosu and yuzu by its small size (~30g), sharper acidity, and intensely aromatic peel. Used in matsutake mushroom dashi (its classical pairing), Japanese udon and soba, ponzu sauces, and as a fine-dining garnish over sashimi. The peel oil is increasingly used in cosmetic and fragrance applications. A Tokushima Prefecture protected regional brand.

Premium Japanese citrus hybrid (Shiranui cultivar of Kiyomi × Ponkan) commercially branded as 'Dekopon' under cooperative trademark. Distinguished by the protruding bump (deko) at the stem, intense sweetness (Brix 13+), low acidity, and easy-peel rind. Kumamoto, Ehime, Wakayama, and Hiroshima are the principal commercial producers. The 'Dekopon' brand requires Brix ≥13 and acidity ≤1.0% for cooperative-trademark use. Substantial premium fresh-fruit export to Asian markets and increasingly the US.

Mid-size sweet-tart citrus (Citrus iyo) almost entirely produced in Ehime Prefecture (>90%). Eating quality balances sweetness (Brix 11-13) with refreshing acidity, and the peel is medium-easy. Iyokan is one of Japan's three most-cultivated citruses by volume (after unshu mikan and dekopon). Substantial fresh-fruit retail and processed-juice supply for both domestic and Asian export. Distinct from sweeter dekopon and tarter kabosu / sudachi varietals.

The Satsuma mandarin — Japan's most-cultivated citrus by volume (~40% of all Japanese citrus production). Wakayama, Ehime, Shizuoka, and Kumamoto dominate. Distinguished by seedlessness, easy-peel rind, and refreshing sweet-tart balance. Beyond fresh fruit, mikan peel (chinpi) is a classical Kampo herbal raw material with long medicinal history; the peel is also extracted for cosmetic applications. The 'Satsuma' name reflects the variety's introduction to the West from Satsuma province (Kagoshima) in the late 19th century.

Apple cider vinegar made primarily from Aomori apples — Japan's largest apple-producing region (>50% of national volume). Mizkan and smaller specialty producers in Aomori process apple cider through 1-2 year barrel-aging into a refined vinegar with rounder, less-sharp profile than industrial apple-vinegar concentrate. Marketed in Japan for digestive-health and metabolic-positioning beverages, and increasingly in Western-style salad dressings. Distinct from existing kurozu-kagoshima black-rice vinegar.

Spring water filtered through Mt. Fuji's volcanic basalt aquifer — a 50-100 year underground filtration cycle that produces water with characteristically high silica content (40-100 mg/L vs typical ~10 mg/L) and low contaminant load. The Fujinomiya, Oshino-Hakkai, and Yamanashi aquifer points produce commercial spring water for both retail bottling and B2B beverage / cosmetic ingredient supply. Distinct from existing Muroto deep-sea-water entry. Used in premium bottled-water retail, sake brewing, and increasingly cosmetic moisturising lines positioning around the silica content.

Premium white-flesh peach cultivars (Hakuhō, Kawanakajima Hakutō, Shimizu Hakutō) cultivated primarily in Okayama Prefecture. Distinguished by exceptional sweetness (Brix 12-15+), white flesh, and a delicate aroma profile distinct from yellow peaches. Okayama produces the iconic 'Shimizu Hakutō' branded variety. Substantial premium fresh-fruit gift-economy export to Hong Kong, Taiwan, Singapore, and increasingly the US. Distinct from existing fruit entries.

Premium Japanese hybrid grape (Kyoho cultivar developed 1937 in Shizuoka) — Yamanashi Prefecture is the leading commercial producer. Distinguished by exceptionally large fruit size (~14g per berry vs ~5g for Concord), intense sweetness (Brix 18-20), and a thick black-purple skin rich in anthocyanin. Used as a premium gift fruit, in juice for premium beverage retail, and increasingly as feedstock for resveratrol / anthocyanin functional ingredients. Distinct from existing yamabudo (wild Japanese grape) entry.

Sweet-potato distilled spirit (honkaku shōchū) — Kagoshima Prefecture's signature beverage with over 100 active distilleries. Production combines locally-grown sweet potato (Kogane Sengan, Beni Otome cultivars) with kuro-koji (black-koji) starter culture. The 'Honkaku Shōchū' GI designation (MAFF, 2005) protects the regional naming. Beyond consumer beverage, imo-shōchū-derived ingredient products (esters, lees-extract) are used in cosmetic and supplement OEMs. Distinct from existing 'awamori-extract' and 'shochu-kasu' entries.

Barley-based honkaku shōchū produced exclusively on Iki Island (Nagasaki Prefecture). One of the four GI-protected honkaku shōchū origins (along with Kagoshima imo, Kuma kome, Ryukyu awamori). Distinguished by light, clean profile from Iki-island barley and the soft volcanic-island groundwater. Roughly 7 distilleries operate on Iki, producing both retail and B2B ingredient supply. Distinct from existing imo / awamori shōchū entries.

Buckwheat-based honkaku shōchū — a niche category dominated by 'Unkai' brand (Miyazaki) and a handful of producers in Iwate, Nagano, and Akita. Distinguished by characteristic buckwheat aroma carry-over from the still. Increasingly featured in Western cocktail bar export under the 'Japanese spirit' positioning. Distinct from imo and mugi shōchū entries; aligns with Japan's broader buckwheat heritage.

Light, delicate-flavoured honey from Chinese milk vetch (Astragalus sinicus, renge) — historically the dominant Japan-domestic honey before acacia took over. The plant is grown as a green-manure cover crop in rice fields, providing both soil nitrogen and nectar source. Production is in continuous decline as fewer farmers maintain renge cover crops; supply commands premium pricing for nostalgic 'kokusan' (domestic) labelling. Distinct from existing acacia-honey-japan entry.

Japanese carbonated soda packaged in the iconic Codd-neck bottle (sealed by a marble pushed down on first opening). Hata Soda (Tokyo, founded 1884) and other regional ramune producers maintain the heritage Codd-bottle production. The iconic packaging and nostalgic Japanese branding make ramune a recognisable export retail item across Asia, North America, and Europe. Original ramune flavour is lemon-lime; modern variants include yuzu, melon, sakura, matcha. Distinct from existing beverage entries.

Premium Shizuoka tea from the Honyama (Abe River basin) region — the historical heartland of Shizuoka tea cultivation since the early Edo period. Honyama's mountainous terroir produces tea with characteristically refreshing aroma and clean astringency, distinct from the warmer-climate Kakegawa. Substantial supply for premium retail tea-bag and bottled-tea programmes. Distinct from existing tea entries (matcha, sencha, hojicha, gyokuro, etc).

Premium Kagoshima tea from the Chiran district (Minamikyushu City). Kagoshima is now Japan's second-largest tea-producing prefecture (after Shizuoka), and Chiran is its most-prestigious sub-region. Distinguished by warm-climate cultivation that yields earlier ichibancha (April vs late-April Shizuoka) and characteristic mellow, low-astringency profile. Substantial export to Asian and Western premium-tea retail. Distinct from existing tea entries.

Japanese Asian pear (Pyrus pyrifolia) — distinguished from Western Bartlett-style pears by round shape, crisp watery texture, and lower aromatic-volatile content. Tottori (largest), Chiba, Fukushima, and Saitama produce the principal commercial supply. The 20-Seiki, Kosui, and Hosui cultivars dominate retail; 'Nijisseiki' (20-Century) holds Tottori-region heritage status. Substantial gift-economy export to Hong Kong / Taiwan / Singapore.

Rice-based honkaku shōchū produced exclusively in the Kuma region of Kumamoto. One of Japan's GI-protected honkaku shōchū origins (alongside Kagoshima imo, Iki mugi, Ryukyu awamori, the existing batch entries). 28+ Kuma distilleries operate in this small region, all distilling rice with kome-koji starter. Distinguished by characteristic floral, light profile from the rice base. Distinct from existing shōchū entries (imo, mugi, soba) and awamori-extract.
