When 30 cm or more falls overnight: check the forecast and lift status the night before, be at the lift 30 minutes early, and never ride trees alone.
A powder day in Japan usually means 30 cm or more of new snow overnight. To get the best of it, check the forecast and the resort's lift status the night before, be in the lift line about 30 minutes before opening, ride with a partner in the trees, and expect the best snow near the lifts to be tracked by late morning.
Japan's big snowfalls come when cold air from Siberia crosses the Sea of Japan and hits the mountains, usually from late December to February. Our snow forecast shows expected totals by resort, and the live cameras let you check the actual depth and visibility before you leave.

Wind matters as much as depth. A storm that brings 50 cm can also close the upper lifts, especially gondolas and long chairs on exposed ridges. Resorts post lift status on their websites in the morning, and it often changes as patrol finishes avalanche control.
Aim to be in line about 30 minutes before the first lift on a big day, longer at busy resorts on weekends and holidays. The first few runs off each lift get the untouched snow. On storm days, lower lifts in the trees often open before the summit, so the best skiing may be lower down.
Eat a proper breakfast. A convenience store rice ball or egg sandwich is fine if your lodging does not serve breakfast early.
Deep snow brings risks that do not exist on groomed runs.
Tree wells are holes of loose snow around the base of trees. If you fall in head first you can suffocate. Ride trees with a partner who stays in sight, and read our tree skiing guide before you go.
Lost skis can sink out of sight. Powder leashes or bright ribbons tied to the bindings help you find a released ski.
Flat sections are where you get stuck. Keep your speed up on traverses and cat tracks.
Avalanche risk rises sharply after heavy snowfall. Stay inside the resort boundary unless you have a beacon, probe, shovel, training and preferably a guide. In Niseko, off-piste access is only through the official gates; see our Niseko gate system guide. Riding closed areas inside a resort is against the rules everywhere in Japan and can cost you your lift ticket.
Powder is tiring. Many injuries happen late in the day when legs are tired, so stop before you are exhausted.
Most Japanese resorts have vending machines at the base and sometimes mid-mountain that sell hot canned drinks, including corn potage soup, usually for under ¥200. A hot can in each glove pocket works as a hand warmer on the chairlift. Convenience store snacks such as fried chicken also travel well in a jacket pocket.
Soak in an onsen. Most ski towns have a public bath within walking distance, and a hot soak loosens tired legs. If you have not been before, read our onsen etiquette guide. Drink water, eat a solid dinner, and dry your gloves and boot liners overnight so they are ready if it snows again. For a ranked comparison, see the best powder ski resorts in Japan.
At busy resorts like Niseko and Hakuba, the snow near the lifts is usually tracked within the first couple of hours. Less obvious trees and smaller resorts hold snow longer.
Not inside open resort runs. You do need a beacon, probe, shovel and the training to use them for any off-piste or backcountry skiing.
