Description
An elegant and minimalist Japanese sakazuki (sake cup) crafted from high-purity 'Jun-Gin' silver. This piece is a 'Trophy Cup' awarded by the Japanese government. It features the distinctive mirror-like 'Bright Finish' characteristic of Japanese metalcraft and serves as both a functional ceremonial vessel and a prestigious token of national honor.
Key Features
The 'Pure Silver' (Jun-Gin) mark and the Kanji inscription identifying it as an official Prime Minister's gift. Its shallow shape and flared pedestal are classic hallmarks of the Sakazuki form.
Material & Composition
Jun-Gin (Pure Silver), typically .999 or 1000 fineness. In Japan, 'Pure Silver' marks indicate a higher purity than Sterling (.925). The piece is solid metal with no mixed materials.
Finish & Decoration
High-polish mirror finish on the exterior. The interior of the bowl (seen as the top surface when in use) frequently features a Paulownia (Kiri) crest in gold vermeil, though here we see the base with a chased/engraved inscription in Kanji characters.
Hallmarks & Stamps
The underside of the foot is stamped 'Jun-Gin' (純銀) which translates to 'Pure Silver'. The bowl features a curved inscription: 'Naikaku Sori Daijin Zo' (内閣総理大臣贈), meaning 'Gift of the Prime Minister'.
Construction Details
The bowl and foot are likely spun or raised from a flat sheet of pure silver and then joined by soldering. The edges are rolled for smoothness. Highly skilled manual polishing is used to achieve the reflective surface.
Functional Features
Single piece saucer-style vessel with a pedestal base designed for ceremonial sake drinking. The wide, shallow bowl is intended for formal toasts.
Handle & Grip Details
N/A - This item is held by the base (pedestal foot) which is integral to the bowl, allowing for the traditional two-handed grip during ceremonial use.
Craftsmanship Details
Exhibits excellent symmetry and a flawless mirror finish. The soldering at the foot-to-bowl junction is invisible, indicating high-quality factory finishing characteristic of Japanese gift-ware.
Authentication Indicators
The presence of the 'Jun-Gin' mark in the correct vertical orientation inside the foot and the specific phrasing of the Prime Minister's inscription are consistent with authentic presentation pieces.
Origin & Manufacturing
Japan. Manufactured by governmental contractors in traditional silver workshops, likely in the Tokyo metropolitan area.
Era & Period
Showa to Heisei Era (Post-1945). These specific presentation cups are synonymous with the Japanese government's recognition of the elderly (Centenarians) or distinguished civil service.
Age Estimate
Late 20th Century (Circa 1963-2015). This style of Prime Minister gift was most common during this period; since 2016, the Japanese government switched to silver-plated versions to reduce costs.
Cultural Significance
Represents the Japanese cultural value of longevity and the intersection of traditional craft with state honors. It is a symbol of a lifetime of contribution to society.
Condition Notes
Very Good. The surface shows light micro-scratching ('hairlines') consistent with handling and light polishing. The Kanji engravings remain crisp. No visible dents or structural cracks.
Value Estimate
$100 - $250 USD. Value is largely driven by its silver weight (melt value) plus a modest collector premium for the governmental inscription and the 'Jun-Gin' designation.
Care & Maintenance
Clean with a very soft cloth and non-abrasive silver cream (like Hagerty). Avoid aggressive rubbing as pure silver is extremely soft and scratches easily. Store in a tarnish-resistant cloth bag.
Similar Pieces
Sterling silver trophies or presentation bowls from Tiffany or Gorham; however, the Jun-Gin purity is unique to Japanese and some Asian traditions, making it softer and more reflective than Western alternatives.
Interesting Facts
Until 2015, the Japanese Prime Minister gave one of these pure silver cups to every citizen who reached their 100th birthday on 'Respect for the Aged' Day. Due to Japan's aging population, the cost became unsustainable, and the cups are now made of silver plate.
