Abstract
The annual extention rate of aluminium production in future would be greater than the mean rate of all industrial production, in Japan as well as in the world.
Japan aluminium industry would need to exploit or manufacture some overseas, bauxite, that would be planned with the co-operation of many aluminium companies, in oder to avoid risks.
Some new process of aluminium manufacture has been tested without success. Consequently, for the several years to come, aluminium industry would continue using the present process, with some improvements.
