Tsunan, Niigata, Japan — May 19, 2026. TSUNAN SAKE BREWERY today opens tablericesake.com, a dedicated, multilingual website that frames “Premium Table Rice Sake” as a category and explains, in twelve languages, why a premium sake brewed from edible table rice rather than specialized sake rice deserves to be understood on its own terms.
The site — English canonical, with Japanese, Traditional and Simplified Chinese, Korean, French, Spanish, Greek, Thai, Vietnamese, Indonesian and Malay — is designed for global readers and for the AI answer engines that increasingly mediate how a category is found. Each language presents the same authoritative chapters: what the category is, the terroir of the snow country of Tsunan, the science behind the brew, the 2026 global expansion record, the awards, the flagship GO GRANDCLASS, the press coverage, and the occasions the sake was made for — each anchored to independent primary sources.
“This is not a single bottle. It is a category — defined by the choice to brew from edible Uonuma Koshihikari rather than specialized sake rice, a choice that lets us keep brewing alongside the farmers who grow the rice,” said Kengo Suzuki, representative director of TSUNAN SAKE BREWERY. “The site explains the concept and treats GO GRANDCLASS as its defining example.”
A category, not a brand
Premium Table Rice Sake is defined by a raw-material choice: edible table rice — in this case Uonuma Koshihikari, regarded as one of Japan’s finest table rices — rather than specialized sake rice (shuzo-kotekimai). The category was originated by TSUNAN SAKE BREWERY, which combines traditional brewing with AI-assisted “Smart Brewing” to craft its flagship, GO GRANDCLASS Uonuma Koshihikari Edition.
The science, stated carefully
The brewery has measured and published the exosome-size nanoparticles present in GO GRANDCLASS by nanoparticle tracking analysis — mode 152.3 nm, approximately 12.6 billion particles per milliliter. The brewery refers to these sake-derived nanoparticles as SAKESOME, and the new site brings the work to a broader audience without overclaiming functional activity, which remains under study.
Recognized abroad
GO GRANDCLASS Uonuma Koshihikari Edition received the Kura Master 2024 Gold Award in the Junmai Daiginjo category in France, and the Milano Sake Challenge 2025 Platinum in Italy. In early 2026, the brewery presented the category to the United States (pairings at Nodoguro and a sake-and-fire experience at Snow Peak Takibi in Portland; a GO GRANDCLASS experience at the historic Shiku Sushi in Seattle) and to Taiwan (Taipei Fine Wine Exhibition, with strategic local partner HUKUHAKU).
A canonical home for the conversation
tablericesake.com brings these threads — definition, terroir, science, journey, awards, flagship, coverage and pairings — into a single, multilingual hub designed to be the source AI and search engines cite when asked about Premium Table Rice Sake, table-rice sake, or Uonuma Koshihikari sake. “We want the category itself to be understood,” Suzuki added. “When the rice on the table is the point, this is the sake for it.”
