Weekly Japan Forecast,Thursday March 5th – A Better Week Ahead With More Snow & Colder Temps

Written late Wednesday, 4th March (Japan Standard Time)
Well folks, this will be my final forecast for the 2025–2026 Japanese snow season. It’s been a solid month of limited snowfall and unseasonably warm temperatures across Japan, with the past seven days in particular delivering very little fresh snow. After an epic January and early February, the Japan snow machine has largely switched off, and we’ve seen considerable snow loss as a result.
However, the next seven days look far more promising, with a few decent rounds of powder and cold temps on the way. Thursday, Sunday and Tuesday are shaping up as the standout days, with the bulk of the snowfall expected then. There are still a few weeks left in the season, and spring skiing brings warmer temperatures, longer days and more sunshine. It’s my personal favourite, so get amongst it!
Thursday March 5hth & Friday March 6th
Thursday will be a powder day of sorts as remaining snowfall across the country gradually dries up. This comes after a storm from the southwest arrived late Tuesday, bringing warm temperatures and rain at first. Temperatures were quick to drop over Northern Honshu and Hokkaido, so there was fresh snow in this Wednesday morning’s reports. However, it was not your usual “lake-effect” Japow; it was denser, maritime snow coming off the Pacific Ocean, akin to what we get in Australia and NZ. As I put pen to paper, snow levels over Central Honshu are also on their way down from the mid-slopes and will get nice and low this Wednesday night.
Friday will stay mostly dry, but there’ll be some isolated flurries lingering on Hokkaido. Temperatures will rocket back up on Honshu as warm southerlies develop ahead of the next storm approaching from the west in the Sea of Japan. Rain from this storm spreads across the country Friday night, falling as snow to fairly low levels on Hokkaido, where temperatures will be much colder.
Saturday March 7thth February & Sunday March 8th
The storm will continue over the country throughout Saturday and Sunday morning, then gradually wind down during the latter half of Sunday. Snow levels about the mid-to-upper slopes of Honshu will gradually lower to base levels by late Saturday, while on Hokkaido, they’ll have to climb over a hill before a period of heavy snowfall to near sea level early Sunday.
Snowfall totals for the weekend are expected to be around 20-50+ cm, with resorts in Niigata and southwest Hokkaido favoured for the deepest totals.
Monday March 9th to Wednesday March11th
Leftover snow showers over northern Honshu will clear up Monday morning, but will persist on Hokkaido.
Central Honshu will stay dry on Monday, but another low-pressure system passing on the Pacific side will pull in a fresh surge of cold air from Monday night, bringing another round of snow for a 10-30+ cm powder day on Tuesday. The passing low will also bring a dusting to northern Honshu and Hokkaido on Tuesday.
A ridge of high pressure will then bring dry, settled weather next Wednesday.
That’s all from me today, and for the season. It’s been a real pleasure bringing you all the snowlights of the 2025-2026 season, which will go down in the history books as having one of the best runs of powder days from Jan through early Feb. See you in June when the Aussie and Kiwi seasons get underway.
