Nidandaki waterfall seen from the back. Hyogo

It is a two-tiered waterfall,but usually only the upper stream flows,and only when the water level rises does the water flow into the lower section.
The back of the lower stream is hollow,and it is also a waterfall to see from the back.
It is a wonderful place where even adults can return to their childhood memories,having been featured in the opening of the national anime"Sazae-san.
