Gear - Natural stones



The history of these mines goes back more than 800 years, when the first Nakayama mine was opened on land owned by a Buddhist temple. These stones quickly gained attention of the local lords, as whetstones were not only useful in military roles, but also in the vital work of carpenters building castles and temples. Since Kyoto was the home of the emperor, who had a vital role in the Shinto religion of Japan, it and the
nearby city of Nara, are filled with beautiful temples and shrines, each of which required the most skilled craftsmen working with the best tools to build and maintain. At that time, whetstones were a constant necessity for these workers. Also because of this, the mine had been protected for a long time by the Emperor of Japan, Shogun or the Japanese Government.

A real Nakayama stone especially a Maruka ㋕正本山 stamp,  said to give a very fine finish, is a highly sought finishing whetstone even in Japan. Because the mine is closed, with dwindling supplies these are extremely difficult to find. The Nakayama mine is thought to be closed more than 30 years ago.


Mines that produce fine razor whetstones. There are over 30 of mines in the area Kyoto, but there are not too many mines that produces hard and fine razor quality whetstones.


Ozuku has a very fine grain, usually quite hard, sometimes too hard and scratchy.  But if the condition is right, it can be an excelent stone for razor finishing.  The quarrying has been stopped for decades but the rough stones that were quarried are still being processed into products.



Mikawa Asano Stamped nagura

The utilization of the Mikawa nagura - (a small stone to create slurry) is a cooperation with Iwasaki's family (famous kamisori maker) and Nagayuki Asano (lecturer).

when Iwasaki-san first started making razors he had trouble with honing. He was getting breaks and chips on his edges, which he eventually found came from the inferior Nagura that were being sold by the merchants–they were cheap, and easily found, and of substandard quality. So he began searching for a long lost source for the Nagura that had been used for centuries in the polishing of Katana.

Aichi prefecture is the only place in Japan that produced the Nagura that Iwasaki-san found suitable for the finest honing and polishing. Not only that, he identified the different seams of the mine, and with the help of geologist Nagayuki Asano divided
them based on their polishing effects, speed, and purity.

Iwasaki Kōsuke’ and ‘Nagayuki Asano’ developed a quality-control system for grading and authenticating Mikawa Nagura. Each piece was carefully inspected, and subsequently ink-stamped to qualify the layer and quality of each stone.

The mine was closed in 1976, all ‘new’ Nagura are cut from large pieces of stock that was mined and stored before then.
