The warmth of handcraftsmanship that Sangenjaya Engraving Studio, established in 1970, continues to preserve.
Beauty that becomes an antique the moment it is completed.
In traditional Japanese jewelry making, there is a design that has been loved for a long time. It is called "tsuchime.
Soft uneven patterns are created when a craftsman carefully strikes the surface of precious metal with a single hammer. One of the most important experiences at MITUBACI TOKYO, an engraving studio in Sangenjaya, is the process of engraving these hammers by the customer's own hands.
A uniquely Japanese sensibility that appreciates "unevenness
While Western jewelry has idealized "perfect symmetry" and "mirror-like smoothness," Japanese aesthetics have found beauty in "fluctuation" and "unevenness," as in the natural world.
The expression of the hammered lines created by each stroke, depending on the strength and angle of the strike, is never the same for two pieces of metal. It is the world's only "record of the heartbeat," the force and the beat of the heart that the couple put into the metal at that moment.
Hammers, the life of an engraving studio and the "partner" of the craftsman
Since our founding in 1970, many hammers have been used in our workshop. In the workshop inherited by our president, Mr. Fujimori, we proudly display the tools that our craftsmen have adjusted over the years to fit comfortably in their own hands.
The tools used in the hammering experience are "real tools" that are actually used in these professional workplaces. The clear sound of the hammer hitting the metal. The pleasant vibration in your hand. All of these elements will sublimate the couple's ring from a mere "product" to a "craft" with a rich story to tell.
A "lifetime" texture that grows with time
The charm of hammered edges is not limited to the moment of completion. As it is worn over the years, the uneven corners will be slightly removed, and the texture will change to a more matte texture that blends more comfortably with the skin.
Even the smallest scratch that occurs in daily life will blend with the hammered pattern and become a part of the ring. It is precisely because the design affirms the "accumulation of time" that it is suitable as a lifelong partner in the form of a wedding ring.
Under the light of Sangenjaya, put your heart into every stroke.
Facing the craftsman and listening to the sound of the Setagaya Line running through Sangenjaya, we hit each and every stroke.
The process is like a quiet meditation. What Fujimori values is "the richness of the time of creation itself. The warmth of human hands and the breath of human life reside in this hammered ring, which cannot be produced by a machine. The stroke of the couple's hand will continue to shine gently on the finger for decades to come.
