Hoketsu Pass

Overview

Hoketsu Pass is a Category 2 climb in Japan, running 7.5 km from a start point at sea level (roughly -1 m) up to a summit of 436 m. The net elevation gain across the ascent is 437 m, which on paper matches the height you see when you look up at the top. It is a compact climb by category standards, short enough to attack but long enough to punish a bad pacing decision.

The catch is what the net gain leaves out. Against 437 m of net gain, the climb racks up 864 m of total ascent. That is 427 m of extra vertical you climb, lose, and climb again — the road undulates rather than rising cleanly. Every metre of descent mid-climb is a metre you re-climb, so the real effort is closer to double the net gain suggests. Treat this as an 864 m climbing day, not a 437 m one.

How the Gradient Unfolds

The 5.8% average is a blend, not a description of any single section. With that much undulation, the average smooths over both the false flats and the sharp kicks. Expect the gradient to swing hard around the mean rather than hold steady.

• Flatter and recovery sections where the road dips or eases — use them, but don't coast
• Repeated short climbs that stack up into the 864 m total ascent
• Steep ramps well above the 5.8% average, where the pitch bites and forces a gear change

Pacing Notes

On a smooth climb you pace to even effort and let speed vary. On Hoketsu Pass the undulation makes that harder: hold your sustainable power output through the steep ramps and resist the urge to hammer the flatter dips to "make up time." Over-cook the early ramps and the repeated re-climbs will empty you before the summit.

Aim for even effort, not even speed. Let your speed rise on the recovery sections and fall on the pitches while power stays steady. If you don't know your number, run the FTP estimator first and pace off that.

Gearing

With the pitch swinging well above the 5.8% average, gear for the ramps, not the mean. A compact (50/34) or sub-compact chainset paired with a wide-range cassette gives you the bailout you need — think 34×32 or 34×34 for the steep sections so you can keep cadence up instead of grinding. Check your setup before the ride; discovering you're a gear short halfway up a ramp is a bad place to learn it.

Summary

• Length: 7.5 km
• Average gradient: 5.8%
• Net elevation gain: 437 m
• Total ascent: 864 m
• Category: 2

Hoketsu Pass reads easier than it rides. The gap between 437 m of net gain and 864 m of total ascent is the whole story: pace to even effort, gear for the ramps, and respect the undulation.
