Is there water?

Whether there is a river here on your dates, and what kind of water it is.

Water-level regime

Snowmelt-driven surge (spring thaw) gives best flows; Kanayama Dam on Sorachi system; rain/typhoon spikes

Runnable window

Approx late Apr-Oct; peak snowmelt late Apr-mid May (Confirm. operator dates)

Best season

Late April to mid-May snowmelt for best rapids; summer-autumn family season

Water temperature

Cold Daisetsuzan snowmelt; early-season water very cold; wetsuit provided; top-class clarity

Spring thaw flooding boosts rapids; typhoon-season (Aug-Oct) rain spikes; cold high water early season

Grade & who can come

Grade at a normal level
Grade 33 (Moderate) - Kokutai course is solid class 3- (pushy set, boulders, ~1.5m drop); commercial tours milder for families

A river changes grade with its level. These grades describe a normal flow - in flood the same run is harder, and often a different run entirely. Check the gauge before you commit.

Local grading

Class 3- (Kokutai course); commercial rafting sections beginner/family grade; Goryu-no-se (class 2) on Shisorapuchi

How it is run

Rafting; canoe/kayak slalom
