Weather
Japan stays in a very active pattern with multiple waves of snow from Monday night (01/19) through Thursday (01/29), led by huge accumulations in central Honshu and steady powder production across Hokkaido. The most prolific stretch focuses on midweek into the weekend, when several reloads stack up for major totals at resorts like Nozawa, Gala, and Akakura, while Hokkaido keeps adding frequent lighter-to-moderate bursts that build deep over time at open areas like Niseko, Kiroro, Rusutsu, and Furano. Snow levels stay very low most of the window, keeping precipitation predominantly snow, with a modest late-period rise at times that can nudge snow quality denser at lower elevations. Snow quality overall trends solid to excellent, with many periods running in the mid-teens to near 20:1, while winds become a primary wildcard at a few exposed zones, especially early and again during select surges.
Monday night (01/19)–Tuesday night (01/20) kicks off with widespread snowfall and generally cold, supportive snow levels that sit near the deck for most areas. Hokkaido starts immediately and keeps producing, with SLRs commonly in the 14–19:1 range, so the snow trends fairly light and skiable rather than wet, and temperatures mostly in the single digits to teens. Central Honshu also gets going, with the first meaningful round landing Monday night into Tuesday, then continuing Tuesday night, and snow levels largely staying low enough for snow at the mountains. Winds are already a factor in a few places, with stronger west to northwest flow and occasional higher gusts that can make exposed ridgelines feel sharp even when snowfall rates are productive.
Wednesday night (01/21)–Monday (01/26) is the heart of the cycle, with repeated reloads that stack up quickly and drive the biggest totals of the forecast window across central Honshu. Several resorts in the Nagano and Niigata zone roll from one round into the next, and the cumulative effect is substantial, with event totals commonly landing in the 40″–80″ range and standouts pushing beyond 100″ by the end of the weekend at the highest-producing locations. Snow quality during this stretch stays mostly favorable, with many periods sitting around 14–19:1, meaning the snow often skis medium-density to light, with only brief denser intervals mixed in. Hokkaido continues adding steadily with frequent bursts and excellent ratios that often flirt with the upper teens, building depth day after day at open resorts, though occasional stronger gusts can accompany the more vigorous bands.
Tuesday night (01/27)–Thursday (01/29) brings an additional push that keeps new snow coming but also introduces the most consistent signal for slightly higher snow levels and somewhat denser snow at times. This late-window wave can still deliver meaningful refreshes, especially where snowfall rates remain steady overnight, but snow quality becomes more variable as SLRs trend closer to the low-to-mid teens in some periods, which points to a heavier, more compact feel compared with the fluffier bursts earlier in the week. Snow levels do rise at times into the several-hundred-feet range and locally higher near 1,000–1,500 feet during select windows, which can translate to denser snow at the very lowest elevations, while mid and upper mountain terrain remains solidly in snow for most resorts given their base elevations. Winds also tick up in a few locations during this late stretch, so expect occasional exposed-lift impacts alongside the continued snowfall.
