Nishizawa Gorge’s Best Season and Seasonal Charm
Nishizawa Gorge displays different characteristics throughout the four seasons, each with unique appeal. The way to enjoy the gorge changes depending on the visiting period, so choose a time that aligns with your objectives.
Spring (Late April to June): Season of Fresh Greenery and Rhododendrons
Spring, when the gorge awakens with snowmelt, is a season when the beauty of fresh greenery stands out. Particularly from late May to early June, rhododendron flowers come into bloom, coloring the gorge. The contrast between pale pink rhododendrons and fresh greenery is a spring-exclusive spectacle.
Additionally, increased snowmelt water raises water volume, amplifying waterfall impact. The sight of waterfalls including the Nanatsu-Kama Gozdan Waterfall flowing down with abundant water is awe-inspiring.
Temperatures are relatively mild, but due to high elevation, mornings and evenings can be cold. Bringing warm layers is recommended.
Summer (July to August): Escape from Heat and Forest Bathing
Summer Nishizawa Gorge makes one forget the sweltering heat of urban areas. Thanks to the high elevation and cool clear streams flowing through the gorge, even midsummer allows comfortable trekking.
With greenery at its densest, this period is when forest bathing effects are felt most intensely. One can thoroughly refresh both body and mind while bathing in abundant negative ions.
While family groups visit frequently during summer vacation, early starts allow enjoyment of trekking during relatively quiet periods. However, afternoon weather tends to become unstable, so aim for earlier action.
Autumn (October to Early November): Spectacular Autumn Foliage
The time when Nishizawa Gorge displays its most vibrant appearance is the autumn foliage season. Typically from mid-October to early November, the entire gorge becomes painted in reds and yellows.
The autumn foliage around the Nanatsu-Kama Gozdan Waterfall is particularly magnificent, and the contrast between emerald-green clear streams and autumn colors is breathtakingly beautiful. Trees along the walking trail also change color, and the scenery transforms with each step.
The autumn foliage period is also when Nishizawa Gorge becomes most crowded. On weekends and holidays, parking lots often fill by early morning, so consider arriving as early as possible or visiting on weekdays. Additionally, with lower temperatures during this period, ensure thorough cold weather preparations.

During winter, the Nishizawa Gorge walking trails are closed due to snow accumulation and freezing. The closure period typically runs from early December to late April, though it may vary depending on that year’s snowfall. Winter entry is dangerous for general hikers and is not recommended. Wait for spring opening.
