Help with information of Education in Japan

[Solpeador]

Hi, I'm Giacomo, and I worked for an investment bank located in Peru. My work is related to the mining sector. So, I just wonder if you know about any institution in Japan that provides short-terms courses in Mining. I assume that Japan in ahaed in technologies related to that field, so I wonder If I can learn a lit bit more about this in Japan. I'm a nikkei.

Thank you in advance,

Giacomo.
