Swift Tanzo Ring is a hand-forged ring, made to order and ready within one week.
Each ring is crafted from scratch to fit your size at our workshop in Sangenjaya, Tokyo, founded in 1970.
“Swift” stands for speed and freedom; “Tanzo” stands for strong forging.
Forging is a method of hammering metal to compress it, increasing its density and strength.
Like swallows soaring freely across the sky, our artisans’ swift and supple craftsmanship
creates refined, beautiful forms with exceptional strength for everyday wear.
Since each ring is made individually, we can also accommodate your detailed custom requests.
Want the finest ring, without the wait? That is what Japanese craftsmanship can deliver.

Inspired by Hanegi Park, where the gentle fragrance of plum blossoms drifts through the air each spring, this ring features a softly matte finish and a texture that recalls the quiet strength and warmth of trees.

Nikotama
(Tax included)
Nikotama
Capturing the landscape of Tamagawa—its wide riverbanks, lush green parks, and the lively town that surrounds them—this design is marked by a single line of delicate milgrain at its center. Like the gentle bond of family, it runs softly through the ring, creating a warm form that quietly accompanies the happiness found in daily life.
Shimouma
(Tax included)
