Shomyo Falls, at 350 metres, is officially recognised as Japan’s tallest waterfall, dropping in four distinct stages down a sheer volcanic cliff face carved by ancient lava flows near the base of the Tateyama Kurobe Alpine Route. An easy walking trail from the car park leads to a viewing platform facing the falls, and in spring, snowmelt sometimes creates a seasonal fifth-stage cascade known as Hannoki Falls, briefly making the combined drop even more dramatic.
