Where is Japan going to build the reservoirs to support pumped storage? They would literally need to blow up some mountains to do it.

Or build it at the top of said mountains?

Well, usually you have many dams in sequence on a river and you can often turn them to pumped hydro by pumping the water from the lower dam back up when you need to store some power.

And Japan has a lot of such cascades - even just in Kurobe there are at least 4 major dams one after another.

But all that capacity is built out. Japan has about the same as the USA in pumped storage capacity...which is a bit amazing considering Japan is just the size of California.
