Handle Upgraded to a Mekugi-Pin Construction
What Makes This Knife Truly Special
A Championship Sakimaru Yanagiba Created by Sakai Masters
This Ginsan Sakimaru Yanagiba was selected as the championship prize knife for the national sushi championship organized by the All Japan Sushi Association in June 2026—a remarkable recognition of both craftsmanship and performance.
With special permission from Shiroyama Knife Workshop, this work is offered exclusively through KIREAJI in an exceptionally limited release.
Both the forging and sharpening were completed by certified traditional craftsmen. The blade was forged by Shogo Yamatsuka and sharpened by Mitsuo Yamatsuka, combining refined balance with precise slicing performance expected at the highest level of sushi craftsmanship.
The handle was created by Toshiyuki Terauchi, a master artisan known for blending traditional techniques with artistic beauty. Trained under the legendary craftsman Mr. Mizuno, whose collaborative work with Hakuhō and Genkai won a prestigious gold prize more than 30 years ago, Terauchi’s work elevates the knife beyond a culinary tool into a true work of art.
This is not simply a knife—it is a symbolic piece representing the spirit of Sakai craftsmanship and Japanese sushi culture.
The Craftsmen Behind the Work
Shogo Yamatsuka
Master of Ginsan and Sakai Forging Tradition
Shogo Yamatsuka began his career as a bladesmith in 1973 under the guidance of his father, a Sakai blacksmith associated with the name “Yuzan.”
Recognized as a Traditional Craftsman in 2012, he is regarded as one of Japan’s distinguished masters of Ginsan steel — a rare stainless steel that requires the sensitivity and precision of traditional forging techniques.
Guided by his belief that “Work never betrays you,” his craftsmanship reflects decades of discipline, dedication, and pride in Sakai knife-making.
