Tsunan Sake Brewery Presents the “GO GRANDCLASS” Experience at Seattle’s Historic Shiku Sushi

On January 14, 2026, following a triumphant debut in Portland, Tsunan Sake Brewery (Headquarters: Tsunan, Niigata; CEO: Kengo Suzuki) brought its vision to Seattle, hosting an exclusive pairing event at Shiku Sushi in the vibrant Ballard district.

The theme of the evening was “Brew for Future.”

In a neighborhood that deeply values heritage and community evolution, we invited guests not just to taste sake, but to taste the trajectory of time itself—from the deep roots of our tradition to the uncharted territories of our future.

A Tale of Two Sakes: “Tsunan” and “GO”

The evening’s curation was a deliberate journey. Guests were first introduced to the “Tsunan” Series, our signature line that embodies the rugged, snow-covered terroir of our home. It served as the “Foundation”—a testament to the unshakeable quality of pure brewing.

Then came the evolution.

We unveiled the GO GRANDCLASS (Uonuma Koshihikari Edition), the embodiment of our “Premiere Table Rice Sake” concept. This was not merely a new product; it was a challenge to the industry’s status quo.

Resonating with “Brew for Future”

The atmosphere at Shiku Sushi was electric. As we shared our philosophy of “Smart Brewing” and community symbiosis—our commitment to preserving nature while innovating with deep-tech—the conversation shifted from flavor to philosophy.

It was in this context that GO GRANDCLASS truly shined.

Guests who resonated with our mission to “Brew for Future” found that the liquid in their glass was the physical manifestation of that vision. They didn’t just taste sake; they tasted possibility.

“Drinking the Tsunan series felt like visiting a pristine, snowy village. But tasting GO GRANDCLASS felt like seeing where that village is going 100 years from now. It is bold, elegant, and undeniably convincing.”

The Potential of “Premiere Table Rice Sake”

By using Uonuma Koshihikari—rice meant for the table, not the tank—we proved that the boundaries of sake are meant to be broken. The feedback was unanimous: this is a sake that commands attention, sparks conversation, and elevates the dining experience to art.

Tsunan Sake Brewery is not just making sake for today. We are brewing for the future of gastronomy, the future of agriculture, and the future of community. We invite you to taste that future with us.
