Taste Sake the Way the Brewer Intended

Experience the true, unaltered flavor profile. The inert steel and mirror finish mean no mineral taste from clay or 'off' notes from glass—just clean, crisp sake every time.

No More Lingering Smells or Stains

Wake up to a clean cup. Unlike porous ceramics, this steel won't absorb odors or stubborn turmeric stains from food. A quick rinse restores it to like-new condition, with 'no smell' as users say.

Perfect Temperature, From First Sip to Last

Stop your chilled sake from warming up too fast. The steel stabilizes the temperature, so your first and last sip are equally refreshing, a detail pros call 'a game changer'.

A Grip That Actually Holds

Never worry about a slippery cup. The hand-hammered Mount Fuji ridges give you confident control, even with condensation or oily fingers, making every pour feel secure.

Effortless Care for a Busy Life

Simplify your routine. It goes from table to dishwasher (top rack) without a second thought. No special hand-washing, no babying—just durable convenience that fits a modern lifestyle.

The Conversation Piece That Shows You Know

Elevate your hosting. This isn't just a cup; it's a piece of functional art from Japan's craft capital. Guests will notice the difference, making your sake moment memorable and distinct.

One Set for Every Sake Occasion

Ditch the specializedware. This set works flawlessly for dry Junmai, fragrant Ginjo, or rich warmed sake. It's the versatile, 'go-to' vessel that simplifies your collection without compromise.

Feels Substantial, Not Cheap

Get that premium 'heft' in hand. The solid, single-piece construction has a satisfying weight that feels luxurious and durable, far from the hollow, tinny feel of cheap metal cups.

1. Rinse cups with warm water before first use. No soap is needed. 2. Pour chilled or warm sake directly into the cup. The steel will quickly equalize to the liquid's temperature. 3. Hold the cup by the textured Mount Fuji design ridges for a secure grip. 4. Sip and enjoy. The smooth rim and polished interior ensure a clean, pure taste with every sip. 5. After use, simply rinse with warm water and dry with a soft cloth. Timeline Expectations: First Use: Notice the immediate difference—sake tastes cleaner with no ceramic or glass 'off-notes'. Week 1: The cups become effortless to care for; no staining, no odor retention. Week 2-3: You start to appreciate the precise temperature control—chilled sake stays crisper, warm sake retains its heat longer. Month 1+: The design becomes a conversation piece, and the consistent, pure tasting experience makes it your default choice for any quality sake.

Born in the metalworking capital of Tsubame-Sanjo, Japan—a region designated by the government for its exceptional craftsmanship—this set was created to solve a common frustration: traditional ceramic cups altering sake's temperature and taste. Our master artisans, with generations of expertise, selected medical-grade 304 stainless steel for its pure, non-reactive properties. Every cup undergoes 37 distinct polishing steps to achieve a mirror finish that meets Japan's stringent JIS G4303 standards. The result is a set that has become the top-ranked premium sake vessel in its category, trusted by over 150 traditional sake breweries across Japan for professional tasting, because it lets the brewer's true craft shine through, without interference.

The Mount Fuji Stainless Steel Sake Cup Set by Yokoyama Kogyo is crafted from high-grade 18/8 stainless steel, a premium alloy composed of 18% chromium and 8% nickel. Chromium is included to form a protective oxide layer that provides exceptional corrosion resistance, ensuring the cups remain rust-free and durable even with frequent use and exposure to liquids. Nickel enhances the alloy's strength and contributes to a lustrous, mirror-like finish that is both aesthetically pleasing and easy to clean. This material choice eliminates the risk of chemical leaching or flavor transfer, offering a pure, unaltered sake-tasting experience. Additionally, the stainless steel's excellent thermal conductivity allows the cups to quickly adjust to the temperature of the sake, enhancing aroma and flavor perception, while its robust construction ensures longevity and resistance to dents or scratches, making it ideal for both casual enjoyment and formal occasions.
