Craftsmanship with Integrity — From a Metalworking Studio in Sangenjaya Since 1970
Introduction: With Gold Prices at Historic Highs, Is Now the Wrong Time to Buy a Ring?
Gold prices are currently at historic highs. Many couples considering wedding rings find themselves thinking, “If only we had bought them a few years ago when gold was cheaper…”—and it’s understandable that some hesitate to purchase right now.
However, our perspective at MITUBACI TOKYO is a little different. Since 1970, we have been observing and working with precious metals as a metalworking studio in Sangenjaya, Tokyo. From our experience, when prices are high, it becomes even more important not to spend on temporary trends or brand names. Instead, choosing a piece that reflects the intrinsic value of the material itself and the craftsmanship behind it ultimately leads to a far more satisfying and meaningful purchase.
Balancing Design Preferences with Lifelong Durability
In recent years, delicate and slender ring designs with a strong sense of fashion have become increasingly popular. Their refined appearance beautifully enhances the hand and adds an elegant, graceful touch. However, when it comes to wedding rings—pieces meant to be worn every day for decades—there are a few important considerations to keep in mind.
- Risk of Deformation:
Extremely thin rings or pieces made with very lightweight metal can be more susceptible to bending under everyday pressure from routine movements. If a ring becomes misshapen, it may also affect the security of any gemstones set in it, increasing the risk of stones loosening or falling out over time. - The Reliability of the Forging Method:
At MITUBACI, we use the traditional forging (tanzo) method, where metal is hammered and compressed to increase its density and strength. With gold prices rising, choosing a ring crafted with a sufficient amount of precious metal and a high-density structure is a wise investment. A forged ring is far more resistant to deformation, helping reduce the need for future maintenance while ensuring your wedding ring remains beautiful for years to come.
Investing in Superior Materials and Craftsmanship — Not Advertising
While studying Italy’s rich luxury jewelry culture, our founder, Fujimori, realized how much of a brand’s retail price often goes toward advertising campaigns and the high rents of prestigious shopping districts.
At MITUBACI TOKYO, we take a different approach. From our own workshop in Sangenjaya, we focus on authentic craftsmanship rather than large-scale advertising. Skilled artisans work directly with each customer, creating a more personal and transparent jewelry experience.
By minimizing marketing costs, we are able to invest where it truly matters: in premium materials such as platinum 950 and 18K gold, and in the expertise of our master craftsmen. Our philosophy is simple—offer fair and transparent pricing that reflects the true weight of the materials and the time required to craft each piece.
This commitment to honest craftsmanship has guided us since 1970, when we began our journey as Fujimori Metal Engraving Atelier. It remains a core part of our identity today.
The Ultimate Fit: How Precise Ring Sizing Creates Lifelong Comfort
Beyond material value, MITUBACI TOKYO is committed to creating jewelry that perfectly fits you. Our professional craftsmen adjust the ring size on the spot, allowing for half sizes such as 10.5, which are rarely available with ready-made rings. We can also make subtle adjustments based on the unique shape and condition of your fingers.
Because a ring is something you wear for a lifetime, we believe there should be no compromises. Our goal is to achieve a fit so precise and comfortable that you can wear your ring every day with ease and confidence.
A Story to Treasure—A Meaningful Gift for Your Future, 10 Years From Now
Gold holds value anywhere in the world. But when it is paired with a one-of-a-kind story—that you shaped it yourselves in a small workshop in Sangenjaya, crafting it together with skilled artisans—the value of that ring becomes truly priceless.
Ten or twenty years from now, you may find yourselves reminiscing about that day—smiling as you say, “I’m so glad we took the time to create something truly our own.”
Moments like these become cherished memories, deepening the bond you share with every passing year.
