TOJIRO KNIFE GALLERY TOKYO – Hanare is a 30-square-metre space designed by L/O (KATATA YOSHIHITO DESIGN) in Tokyo’s Asakusa and Kappabashi district.

Rather than functioning solely as a place to purchase knives, Hanare was conceived as a point of consultation and an ongoing connection between the manufacturer and its users. It currently serves as a business contact point and presents one-of-a-kind and limited-production knives, with custom and made-to-order services planned for the future.

The interior translates the progression of knife production—from raw material through transformation to completion—into an architectural sequence. At the threshold, closely spaced iron louvers reinterpret the vertical rhythm of senbon-goshi, a traditional Japanese lattice. By replacing wood with iron, the element connects the repeated metal components found in Tojiro’s factory with the spatial rhythm of traditional Japanese architecture.

The recessed knife displays are lined with charred cedar. The surface was carbonised and brushed using an uzukuri technique to emphasise the grain. Rather than reproducing the appearance of factory machinery, the wall refers to the way fire transforms a material during knife production. Its grain also recalls the Damascus patterns and hamon-like expressions found on knife blades, while the dark carbonised surface allows the cutting edges to catch the light.

At the centre, a naturally shaped river stone collected near Tojiro’s factory in Niigata and a precisely fabricated stainless-steel cabinet support a transparent glass top. Only the contact point of the stone was flattened; most of its original form and surface remain intact. The glass was introduced to keep the relationship between the natural stone and the industrially produced cabinet visible.

The material palette includes earth and straw from the Tsubame-Sanjo region, Yasuda kawara tiles, natural stone, charred cedar, iron, stainless steel and glass. These materials bring the landscape and manufacturing culture of Niigata into a compact space in Tokyo, connecting the origins of matter with the processes through which it becomes a precisely made tool.
