Aji Project Aji Stone Door Stopper FUJ #1

Aji Stone Door Stopper "FUJ #1" — Handcrafted in Takamatsu, Kagawa

A Rare Japanese Granite Quarried Only in Takamatsu, Kagawa

Aji Stone is a granite quarried exclusively in the northeastern corner of Takamatsu City, Kagawa Prefecture — nowhere else in the world. Its defining characteristic is density. The particles that form its grain are exceptionally fine and tightly bonded, giving it a Mohs hardness of 7, on par with quartz and nearly twice the hardness of marble (Mohs 4). That density also means low moisture absorption — Aji Stone does not stain, does not weather, and does not degrade. Objects made from it outlast the contexts they are placed in.

Hand-Finished by Stone Artisans in Kagawa

Aji Stone's hardness makes it notoriously difficult to work. In Takamatsu, artisans who have dedicated their careers to this material handle every stage of production — quarrying, cutting, shaping, polishing, and finishing — each requiring different tools and different judgement accumulated over years. The knowledge moves from person to person, generation to generation, and cannot be substituted by machinery alone.

A Refined Stone Door Stopper That Reveals Aji Stone’s Character

FUJ #1 reduces the door stopper to its essentials: a cylinder of Aji Stone with a rope threaded through its center. No base, no rubber feet, no mechanism. The weight of the stone — 3.2 kg — does the work. The cylindrical form is precise but not cold; the natural variation in the stone's surface gives each piece its own character.

Bringing Aji Stone into Modern Interiors

This granite door stopper pairs Aji Stone’s quiet gray tones with colored rope, adding a contemporary contrast to the traditional material. The result sits easily in both Japanese and Western interiors: present without demanding attention, noticed when you look for it.
