From about 0.20 m³/s in the lowest month to 0.99 m³/s in the highest. Best months to go, with plenty of water and pleasant days: from May to July and 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.
Ōko Falls is a waterfall in Japan.
