For most ski areas in Japan, the season generally starts in mid-to-late December and ends around late March or early April. Season dates depend on the region, individual ski area, and snowfall in any particular year.

In this section, we present details on recent seasons and provide a general overview of the Japanese ski season.

The early season

A few ski areas try to open as early as possible using artificial snowmaking machines. It is always a race to be the first ski area to open, and the winner is invariably Snow Park Yeti in Shizuoka Prefecture.

The first day often features people turning up in cosplay fancy dress and, like clockwork, it is reported on the national news.

Some higher-altitude and better-known ski areas aim to open in late November or early December, but it is usually mid-to-late December when the majority open.

December is often a month of anxiously waiting for the snow to arrive, and it can be a risky period if you are planning to visit from afar. The risk can pay off, though, as conditions can sometimes be excellent by Christmas.

One thing to note is that if a ski area has announced an official opening date, it will probably stick to that date even if there is enough snow to open earlier.

The peak season

Most people would probably agree that, on average, the peak of the Japanese winter season in terms of snow quality is from mid-January through to mid-February.

That period is also the most popular, so busier slopes should be expected, and accommodation and lift ticket prices may be higher.

The spring season

March can still bring some fine gifts from the skies, but conditions are often becoming more unpredictable by then, and it can start to feel like spring.

Ski areas that remain open into late March usually switch into an official 'spring ski' mode, often offering reduced lift ticket prices for the final part of the season.

Some ski areas traditionally remain open until the end of the Golden Week holiday period in early May, while a few continue even beyond that, making the most of the snow that remains.

Unique opening dates

A few ski areas have particularly unusual operating seasons.

Due to heavy snowfall making access impossible during winter, Gassan in Yamagata Prefecture does not usually open until April and often remains open into July.

At one time open throughout the winter, Nakayamatoge in Hokkaido later switched to operating only during the early and late parts of the season, closing for much of the core winter period before reopening in spring. From 2025, it has operated only for a short period in spring.

Another curious example is Okutadami Maruyama in Niigata Prefecture. The Silver Line road providing access to the ski area closes during the middle of winter, meaning the ski area opens for a period in early winter, closes for several months, and then reopens again in spring.

Some small ski areas, particularly in Hokkaido, close on Mondays as well as on New Year's Eve and New Year's Day. Quite why this practice appears to be especially common in Hokkaido is not entirely clear, but it is something worth being aware of.

Another trend that has emerged in recent years is some lesser-known ski areas operating only on certain days of the week rather than every day throughout the season. We try to communicate such information on our ski area listing pages, but it is always worth checking in advance before setting off for a smaller ski area.

The popular periods

The image of Japanese slopes packed with people and offering almost no space to ski is outdated in most places and on most days.

Weekends and national holidays at popular ski areas can still be extremely busy and are best avoided if possible, especially at the really popular places. (One more reason to research our Ski areas listings, perhaps!)

On weekdays, however, many ski areas are surprisingly quiet.

At less well-known ski areas, you may find yourself sharing the slopes with only a handful of other people. Quiet slopes are one of the bonuses of choosing smaller and less popular destinations. You might even find yourself wishing there were more people around.

Traditionally, the busiest periods are the New Year holidays, the three-day weekend in mid-January, national holidays that connect with weekends, and, particularly in recent years, the Chinese New Year holiday period.
