--The pride of our multi-skilled craftsmen who have inherited the techniques established in 1970.
MITUBACI's "Speed and Precision" Surprises Even the Highest Brands
Even for the world's leading high jewelry brands, it usually takes weeks or months for a ring to reach you. The reason for this is that most jewelry production is a "division of labor. Someone polishes the ring, someone fastens the stones, and someone adjusts the size. At each step of the process, the ring travels to a different craftsman and a different factory.
However, at MITUBACI in Sangenjaya, Tokyo, one artisan completes the entire process right before your eyes. That is why, in just a few hours during your trip, you can bring home "on the day" a world-class standard of quality.
The luxury of "one master artisan per couple
At MITUBACI, one craftsman is dedicated to each customer, from the initial consultation and instruction in metal "forging," to the final precision turning and stone setting.
- Don't drop the baton of love:. In a division of labor system where the person in charge changes at each step of the process, the customer's detailed attention to detail can fade away like a game of messages. We believe that the most beautiful ring is created when one person takes the couple's wishes from beginning to end.
- A "multi-skilled worker" who combines all skills:. Our craftsmen are not "partial professionals" who only polish or set stones. Only those who have passed the strict standards of our workshop, which has been in existence since 1970, are in charge of your precious time.
What we can do because we are an "in house workshop" in Sangenjaya
Ever since our representative Fujimori inherited the Sangenjaya workshop from his father, what he has cherished is the live-work experience of "completing everything in this place. We embody the "culture of direct connection between craftsmen and customers" that we learned in Italy, with our unique Japanese high technology.
- Comes to life before your eyes:. The hammered pattern tapped by the two of you is put on a lathe by a craftsman on the spot to create a beautiful edge. The fire is used, the stone is clamped, and the engraving is done. The peace of mind that comes from being able to closely observe the entire process can never be experienced in a factory with a division of labor system.
- Do not break your travel schedule:. Since there is no outside shipping involved, the process can be completed in as little as two hours. Even if you are coming from far away, you can be on your way to your next destination that evening with your new ring.
A "lifetime of peace of mind" promised by Sancha's engraving studio
The fact that one craftsman is in charge of everything means that he or she knows "everything" about the couple's ring. When you need to have your ring resized or maintenance work done a few years later, the "craftsman who took care of it that time" will be there to see you again. This face-to-face relationship of trust is the pride of Sancha's workshop, which has been in operation for half a century.
Please come and experience these "miraculous few hours" in between trips to Tokyo.

❓ Frequently Asked Questions (FAQ)
Q: Isn't it difficult for one craftsman to do the entire process?
A: For highly trained craftsmen, it is their consistent grasp of all processes that allows them to perfectly balance and finish the entire process. This is the strength of the Japanese craftsman, known as a "multi-skilled craftsman" (tanou-kou), who encompasses multiple skills.
Q: Can you do difficult processes such as stone setting on the spot?
A: Yes, we do. The setting of diamonds and birthstones are all done in our workshop by our skilled craftsmen. The work is completed while the couple enjoys lunch or a stroll afterwards.
Q: Can I ask questions to the artisans during the production process?
A: Of course. The greatest advantage of integrated production is that you can talk directly with the craftsman at each step of the production process. In a workshop where there are many things you will see for the first time, you will probably have many questions about what is being done and what are the tools used for. Please don't hesitate to ask questions.
Q: Is the shop location easy to find?
A: Yes, we are located in Sangenjaya, Tokyo. We are about a 1-minute walk from Sangenjaya Station, very close to Carrot Tower. The store is an integrated workshop, so when you step into the store, you will hear the pleasant sound of craftsmen at work. Even first-time visitors can come in without hesitation.
