Mines

Since our foundation in 1920, we have maintained mines nationwide.
We produce high quality and highly white crystallized limestone with few impurities.

In resource-poor Japan, limestone is an exceptionally abundant resource.
Our company had focused attention on high quality and highly white crystallized limestone, has since been securing it as a resource, and mined. We have realized stable supply system by allocating operating mines both in east and west Japan.

Shin-takine Mine (Fukushima Prefecture)

The Asahitakine Mine (taken over June 2001 from Sumitomo Osaka Cement Co., Ltd.) and the Asahi Ohgoe Mine merged in October 2011, giving birth to the Shin-takine Mine.
The current operating mining area is approximately 7,450,000㎡ with several hundred million tons of ore stored, and is regarded as Japan’s leading mine in the field of crystallized limestone.
5km east of JR Ohgoe Station, this region is a tourist destination, with the calcareous caves of Abukumado and Irimizusyonyudo. The neighboring town Miharu is famous for its cherry tree.
