Tsunan Sake Brewery

We’re excited to introduce a new creation from Tsunan Sake Brewery — the “Yukigesho Castella”, a sake lees-based cake inspired by the snowy landscapes of Tsunan. ❄️🍶🍰 Developed at the Sustainable Food Lab in Toranomon, Tokyo, this castella cake features a moist texture thanks to sakekasu (sake lees) and is accented with our dessert-themed sake GO DOLCE, delivering a rich, elegant flavor. The top layer, reminiscent of snow makeup (“yukigesho”), is crafted using sake lees for both visual beauty and umami depth. This initiative is part of our Sake Upcycling Project, which transforms byproducts of sake brewing into new value — from gourmet food to materials innovation. By bringing new life to sake lees, we aim to contribute to a more circular and sustainable food future. We’ll be showcasing this new cake at various events soon. Stay tuned! 🌱 Learn more about our sustainability efforts: https://tsunan-sake.com/ #TsunanSake #SakeUpcycling #SustainableFood #FoodTech #Sakekasu #FermentationInnovation #CircularEconomy #NiigataSake #GOseries #YukigeshoCastella #GODOLCE #SnowyNiigata #CraftSake #JapaneseSake #SakeCulture #SustainableInnovation #TsunanTown #FoodDesign #FutureOfFood #RegenerativeBusiness

We are honored to announce that Tsunan Haku, our gold medal-winning sake from the 2025 National New Sake Appraisal, was featured at the Public Tasting Event held in Ikebukuro, Tokyo.

We are excited to share that Tsunan Sake Brewery has launched the Sake Upcycle Project, an innovative initiative to explore new possibilities for sake by-products such as sakekasu (sake lees). Through collaborations with research institutions and companies from diverse industries, we aim to transform sake lees into advanced materials like carbon-based semiconductors, develop applications for sake-derived nanoparticles (SAKESOME), and explore their potential as ingredients for cultured food products. This project is part of our ongoing effort to create a circular economy from the heart of Niigata, combining tradition and innovation.

We are pleased to share the latest milestone from Tsunan Sake Brewery: In collaboration with Okayama University of Science and Space Seed Holdings, we have successfully prototyped graphite derived from sake lees using Spark Plasma Sintering (SPS) technology. As part of our Sake Lees Upcycling Project, this initiative explores new possibilities for transforming brewing byproducts into high-value carbon materials, contributing to sustainability and circular innovation rooted in Japan’s traditional industries. We look forward to continuing this journey, creating advanced materials such as sake lees-derived graphene and carbon nanotubes, while deepening partnerships with academia, industry, and local communities. #TsunanSakeBrewery #SakeLeesUpcycling #Sustainability #CircularEconomy #MaterialScience #Graphite #SparkPlasmaSintering #Innovation #Japan #JapaneseSake

We had the honor of welcoming a delegation from Yeoju, South Korea—Tsunan Town’s sister city—at Tsunan Sake Brewery Co., Ltd. last month.
