Born in Tsubame-Sanjo, Japan—a city designated by the government as a 'Traditional Craft Production Area' for metalwork—this cup answers a modern problem: enjoying premium sake is often hindered by subpar vessels that alter taste. Our master craftsmen, whose families have polished metal for over a century, developed this formula: surgical-grade stainless steel shaped by a patented 12-step hand-polishing process. Every cup undergoes a 48-hour quality inspection against Japan's Industrial Standards (JIS) to ensure a flawless, non-reactive mirror finish. The result isn't just a cup; it's a calibrated tool for taste. It's the top-ranked sake cup in its category on Rakuten Japan for 3 consecutive years, chosen by over 50,000 users for delivering what they call a 'pure, no-smell taste'.

The Premium 70ml Stainless Steel Mirror Finish Sake Cup by Yokoyama Co., Ltd. is crafted from high-grade 18/8 stainless steel, which comprises approximately 18% chromium and 8% nickel. Chromium is included to form a passive oxide layer that provides exceptional corrosion resistance, ensuring the cup remains unaffected by acidic beverages like sake and preventing metallic taste transfer. Nickel enhances durability and contributes to the austenitic structure that gives the steel its non-magnetic properties and superior formability, allowing for the precise, seamless construction of the cup. The mirror finish is achieved through advanced polishing techniques that smooth the steel surface to a reflective sheen, not only for aesthetic appeal but also to facilitate easy cleaning and hygiene maintenance. This material composition ensures the cup is dishwasher-safe, resistant to tarnishing and rust, and maintains the temperature of sake effectively, offering users a durable, hygienic, and visually striking vessel that enhances the traditional sake-drinking experience with modern practicality.
