Gate Description

Gate 9 — the Waterfall gate — links Hanazono and Hirafu ski areas and is one of Niseko’s less-skied gems. While short, it offers one of the most fall-line consistent descents on the mountain, flowing through well-spaced trees with some of the deepest pockets of wind-deposited snow.

It is named for the waterfall that is visible from the terrain, and that creates this gate’s main hazard – a river crossing. Mid-season snow bridges are usually solid, but they thin as the snowpack warms, so plan your line carefully; skiers fall in each year.

The gate faces south to south-east and is sheltered from the prevailing north/northwest wind, so it loads deep with snow blown from more exposed slopes and often holds pockets of light snow between the trees for days after a storm. Being a southerly aspect, it is sun-sensitive: through the cold of mid-winter (December to February) that barely matters and it rides well at any hour, but from spring (March–April), or during an unusual warm spell, the sun works the slope and turns it heavy quickly.

When It Rides Best

A south/south-east gate sheltered from the prevailing wind — it loads deep, and through the cold of mid-winter it rides well at any hour.

Cold conditions after a north/northwest storm — the sheltered aspect loads deep and the wind pockets between the trees hold light snow for days
Through December to February the snow stays dry whatever the hour — no need to rush it
Most light conditions — the trees give contrast and definition, so it rides in flat light
When the summit is in cloud or wind-closed and you want reliable, no-hike terrain

When to Stay Away

The base creek crossing is the year-round catch; sun on this southerly aspect only matters once it warms up in spring.

When skiing alone — the unavoidable river hazard makes this a gate to avoid without a capable partner. If you do not have a buddy, consider hiring a guide.

Finding Your Way In & Out

Dropping In

Turn left when arriving at the top of Hanazono #2 and do a very short walk to the gate. Gate 9 sits on the boundary between Hanazono and Hirafu; follow the ridge for as long as you please and drop when you see the least tracked snow for a consistent fall line ski through the trees. A very short (or no traverse) will provide the safest route back to the piste. A longer traverse will likely provide a less tracked ski, but at the expense of a more challenging creek crossing.

Getting Back

The lower section funnels toward the creek at the base. Cross the creek and exit skier's left. Maintain enough speed through the lower section to reach the Holiday piste in Hirafu.

Local Knowledge

Its awkward location, between Hanazono and Hirafu, makes the waterfall gate a surprisingly unskied slope considering how deep the powder can get when wind-loaded. It is a good option before lunch or at the end of the day.
A longer traverse will take you to an excellent section of steep, tight trees that hold powder several days after a storm.
Sticking along the ridge, and not dropping towards Hirafu at all, reveals a rarely skied ‘secret’ slope taking you back to Hanazono.

Before You Go Through Any Gate — What to Carry

Carry — and know how to use — a transceiver (beacon), probe and shovel. Wear a helmet, never ride alone, and tell someone your plan and expected return time.

This equipment can save your life and the lives of others in your group. Carrying it is not enough on its own: practise with it until using it is second nature. Check the daily NAIC avalanche bulletin and the gate status before every session — gates open only when patrol judge conditions safe enough, and that can change within hours.

Not Confident? Book a Guide

Niseko's gates reward local knowledge — of how the snowpack reacts to wind and temperature, and of where each line safely exits. If you're new to the backcountry, unsure about the day's conditions, or riding technical terrain for the first time, a certified guide is the fastest route to a safer and better day.
