Mure-Town and Aji-Town are located in Eastern of Takamatsu-City, Kagawa Prefecture. Aji stone is quarried from Mt.Yakuri-Goken which straddles the boundary of that two towns.
In the latter half of the Heian period(around thousand years ago), Aji stone was already used as a building material, and full-scale quarrying was done when Takamatsu Castle was built in 1588.

It is said that the stone industry in Mure-town and Aji-town developed around 1814 when Yashima Toshogu(shrine) was built, and the history of the production area is more than 400 years.

Aji stone is a type of granite, but among them, the crystals of its constituents are very fine and have strong bonds, and it is characterized by its hardness equivalent to that of quartz and its resistance to weathering. It is also called "blue granite" because it contains the biotite in a bluish tint.
Since high technology is required to handle this rare material, there are highly skilled craftsmen in all processes from quarrying to processing in the Aji stone production area.

It is said that human beings were born 300 thousand years ago, but Aji stone was formed 80 to 90 million years ago, and appeared on the surface of the earth 20 million years ago.
Aji stone - These craftsmen face every day, and what we have now in our hands can be called the mother earth that has existed long before the birth of humankind.
