high water best months to go

From about 0.47 m³/s in the lowest month to 3.0 m³/s in the highest. Best months to go, with plenty of water and pleasant days: from June to September.

Estimate: the timing comes from rain, snowmelt and evaporation (NASA POWER, 1991–2020); the amounts from the river model of HydroATLAS (WaterGAP, 1971–2000). Dams upstream can change the real flow.

Nishishiiya Falls is a waterfall in Japan. The water falls 86 m.

1.1 MW

About 1.3 m³/s falling 86 m: the power of the water as it drops.

enough to power about 284 homes, if it were all turned into electricity

Power of falling water = density × gravity × flow × height. Average flow and height as shown above; an estimate.

The 日出生川 through the falls

The line follows the river as mapped in OpenStreetMap; heights from the 30 m Copernicus model, which smooths narrow drops — the published height of the falls is the one above.

The valley below the falls

Around the falls the river drops 97 m in 2.1 km. Here the river runs about 58 m below the lower rim of its valley.
