Karikachi Pass

Overview

Karikachi Pass is a Category 3 climb in Japan, running 11 km from a valley floor at 222 m up to a summit at 628 m. On paper it is a modest ascent: 406 m of net elevation gain spread across the full distance, which works out to an average that never looks intimidating in a route file. It is the kind of climb you can ride steadily without ever feeling truly pinned, provided you read the terrain rather than the summary.

The numbers hide something important. While the net gain is 406 m, the total ascent is 568 m. That 162 m gap is elevation you climb, give back on a descent, and then have to climb again. The pass undulates rather than rising cleanly, so your legs pay for more vertical than the net figure implies. Expect the effort to feel harder than a simple 406 m climb, because the rolling profile keeps interrupting any rhythm you build.

How the Gradient Unfolds

An average gradient of 3.68% is misleading here. Because 162 m of the ascent is offset by descent, the flat-looking average is really the sum of steeper ramps and downhill recoveries averaged together. The road stacks up as a series of climbs and dips rather than one consistent grade, and the steepest ramp bites at 12.17% — more than three times the average and enough to force a gear change.

• Flatter and downhill recovery sections where you can spin, drink, and reset
• Repeated short climbs that interrupt any settled rhythm
• A steepest ramp of 12.17% that demands your easiest gear and a brief hard effort

Pacing Notes

On an undulating climb like Karikachi, chase even effort, not even speed. Hold a steady sustainable power output through the dips and the ramps, letting your speed rise on the flatter recovery sections and fall on the 12.17% pitch. Riders who try to hold constant speed blow up on the steep ramp and coast the descents — the worst of both. Know your ceiling before you start: run the FTP estimator so you can put a real number on the effort you plan to hold across all 11 km.

Gearing

The gradient that governs your gearing is the steepest one: 12.17%. To turn that ramp comfortably at 11 km into a ride, fit a compact or sub-compact chainset paired with a wide-range cassette — a 34×32 or 34×34 gives you the range to keep cadence up when the road kicks. Check your setup before the ride, not at the base of the steep pitch. A cassette one size too small turns a manageable ramp into a grind.

Summary

• Length: 11 km
• Average gradient: 3.68%
• Maximum gradient: 12.17%
• Net elevation gain: 406 m
• Total ascent: 568 m
• Category: 3

Karikachi Pass rewards riders who respect its rolling profile. The 406 m net gain undersells the 568 m you actually climb, so pace on effort, gear for the 12.17% ramp, and let the descents be recovery rather than a reason to over-push.
