900m is a huge elevation difference. The highest pumped power dam currently in Japan (by hydraulic height, after looking at almost all the Japanese hydro pages on English Wikipedia) is about 780 m; the median is just under 400 m. Presumably most of the other hydroelectric dams have already been investigated for pumped power, but lack a sufficiently large lower reservoir. |
