How do you ride powder on a snowboard? No brakes: speed and turn shape

This post is about powder inside the resort’s managed area: terrain where the lifts are running and the resort lets you in. Backcountry outside the managed area is a different matter; it comes up again further down.

The tail swing you learned on groomed runs to slow down stops working the moment you enter powder. Swing the tail, the speed is gone, and you sink.

This post is useful if you:

• are meeting powder for the first time in Hokkaido and keep sinking
• are used to steering in powder by swinging the tail
• want to know why powder boards look different from regular snowboards

What follows are the views and notes of SnowWind’s vice principal, 西西, drawn from 西西’s Threads posts of November 2026 and 西西’s teaching notes. This is not text from JSBA teaching materials.

Why you sink

西西 gives “skidding” a concrete definition: steering in powder by swinging the tail, again and again.

西西’s judgement is that this kind of skidded turn slows you down a great deal, and does not control direction precisely enough.

In powder there is no such thing as brakes. Every bit of slowing down should be done with turn shape and terrain.

西西

西西 also has a way of splitting points across the three elements. The three elements of snowboarding are edging, pressure and rotation. Say your skill is worth 10 points:

Setting	Edging	Pressure	Rotation
Groomed runs	5	3	2
Powder	3	1	6

The reasoning: on a groomed run, once the board is on edge it carries itself; in powder, too much pressure and the board sinks. This is 西西’s split from experience, not a measured figure.

Key point: in powder, swinging the tail costs you speed and too much pressure makes you sink. Slow down with turn shape and terrain.

Speed and turn shape

Why the emphasis on speed? 西西’s explanation lies in the nose. In powder the board rides on its base, not its edges; only with enough speed does the snow push up on the nose hard enough. In another post 西西 wrote that at high speed the board floats more easily, and once it floats there is less resistance, so small movements of the torso are enough to steer.

On turn shape, 西西 puts it this way:

Every turn is a precise measurement of the snow you are on right now. The feedback from this turn brings the information the next turn will need.

西西

Writing on another topic, 西西 said something similar: the fuller the turn, the finer the speed control — rather than killing your speed in an instant.

In the trees, as 西西 sees it, a strong rider is not thinking about how to avoid the tree ahead. The turn shape is already in mind before the turn begins, and the rider uses that shape to pass through the gaps between the trees.

西西’s verdict is blunt: you can get down powder swinging the tail the whole way, but you are still a long way from the pleasure powder can really give. That is 西西’s feeling, not a technical grade.

The high-speed freeride 西西 talks about belongs to big mountains, outside the resort’s managed area. For backcountry outside the managed area, take formal training and go with a qualified guide; on avalanche risk, see Can avalanches in Hokkaido be predicted?.

Your board changes how you turn in powder

西西 says the design logic of a powder board is the reverse of a regular board’s: a regular board tries hard to cut into the snow, while a powder board looks for ways not to.

The design points 西西 lists:

• Nose: upturned and made wider, so the snow can push it up more easily and it does not dive in.
• Edges: the effective edge is often very short, with the contact points at either end far from the nose and tail. According to 西西 this is deliberate: in deep snow, the longer the edge, the more easily it trips and catches.
• Tail: the opposite logic to the nose. It is meant to sink, so it is made narrow, and some are cut into a swallowtail.

The example 西西 gives is Gentemstick, from Niseko, which has a Short Camber design: both ends of the edge stop before the board’s widest points and run straight into the upturned nose and tail. The aim is fewer edge catches.

This is 西西’s breakdown of the design; the editors have not separately checked it against what the manufacturer says. Whether to rent a powder board is not something this post answers. It depends on the snow and your level; you can ask your instructor directly during a lesson.

Practising trees and powder inside the resort

SnowWind’s Snowboard Tree & Powder Lesson runs at Rusutsu, Sapporo Teine and Asarigawa Onsen. Every lesson takes place inside the resort’s managed area, in terrain the resort permits and has open that day.

The level required: you can already ride fluent linked S turns on red (intermediate) runs on your own. The school checks your level before you book, and a helmet is worn throughout. Content and prices are on the courses page; for each resort, see Rusutsu (in Chinese), Sapporo Teine (in Chinese) and Asarigawa Onsen (in Chinese).

For why Hokkaido powder is the way it is, read The Science of Powder, Part 1. The next part covers Hokkaido snow in November.

Who this post is not for

• Anyone who cannot yet link turns on red runs: get your turns steady on groomed runs first, then think about powder.
• Anyone looking for routes outside the managed area, or for speed figures: this post has none, and that is not something one article should decide.

The views and the point split in this post come from 西西's Threads posts of November 2026 and 西西's teaching notes; the board design points are 西西's personal breakdown. For course information, the courses page takes precedence. The views of KAKU and 西西 do not represent JSBA's official position.
