The water at Mikaeri Falls, month by month
It roars from June to August.
The fullest months: from June to August. The thinnest: January.

From about 0.14 m³/s in the lowest month to 0.90 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.
Mikaeri Falls is a waterfall in Japan. The water falls 100 m. It lies within Tenzan Prefectural Natural Park.

377 kW
About 0.38 m³/s falling 100 m: the power of the water as it drops.
- enough to power about 94 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 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.
Around the falls the river drops 225 m in 2.2 km. Here the river runs about 183 m below the lower rim of its valley.
