General Information for Green Season

Planning a trip to Shiga Kogen? This page covers everything you need to know before you go.

Major cities such as Tokyo, Nagoya, and Kyoto offer all the convenience, entertainment, and shopping you could ever want. They represent the fast-paced and modern side of Japan: exciting, energetic, and vibrant. In contrast, Shiga Kogen is completely different.

Here, you won’t find the usual trappings of modern life, such as shopping centres or leisure facilities. Instead, you’ll discover something far rarer: breathtaking landscapes that can’t be found anywhere else.
Although it may not be the most convenient place, this is exactly what makes it truly restorative — a genuine escape from the demands of everyday life.

To be clear, it’s the modern conveniences that are lacking. What Shiga Kogen offers is something far more valuable: the natural beauty that locals and visitors alike have preserved for generations.

Much of the region is part of a national park, designated as a UNESCO Man and the Biosphere (MAB) Reserve. Take your time, slow down, and immerse yourself in the vast and peaceful nature that defines Shiga Kogen.

So, why not take a break from the noise and rush of the city, and enjoy the beauty of having “nothing” in the very best sense of the word?
 

 

Overview

Shiga Kogen: A Natural Treasure within a National Park

Nestled in the heart of Joshin’etsu Kogen National Park, Shiga Kogen is more than just a beautiful place to visit — It’s a place that helps preserve a natural environment of global significance.
It’s been recognised as a UNESCO Man and the Biosphere (MAB) Reserve, and is one of only ten places in Japan to have earned that title.

This highland area is home to a wide variety of ecosystems, striking scenery, and a world where humans and nature coexist in harmony.
From ancient forests and peaceful upland wetlands to still ponds, snow-covered peaks, and plenty of wildlife, the landscape changes with the seasons and offers something new each time you come.

Of course, with beauty comes responsibility.
This delicate environment is the result of generations of balance between people and nature. Looking after it depends not just on the locals, but also on those who visit.

Whether you’re walking the trails, soaking in a hot spring, or simply enjoying the mountain air, we hope you’ll experience Shiga Kogen with care, curiosity, and a sense of wonder.

Shiga Kogen: Home to Diverse Wildlife and Pristine Nature

Shiga Kogen is home to a wide range of wildlife, including Japanese hares, red foxes, macaques, serows, and even Asiatic black bears. If you’re very lucky, you might just spot an ermine – a rare treat, even for the locals!

In these quiet forests, birds sing cheerful tunes and insects gather around delicate mountain flowers. Every creature here plays its part in a vibrant, living landscape – all made possible by the beautiful natural surroundings.

To help protect these animals and their delicate habitat, please keep the following in mind:

  1.  Do not feed or touch wild animals. Avoid making loud noises if you see them
  2.  Be sure to keep your distance while taking pictures of animals
  3.  Do not pick plants
  4.  Stay on marked hiking trails (plants here are very delicate)
  5.  Be sure to take all your rubbish with you
  6.  Use a bear bell and avoid hiking alone whenever feasible
  7.  Drive carefully — animals may cross the road unexpectedly
  8.  Strict rules apply to stream fishing. Please inquire in advance

Thank you for your consideration… your cooperation helps preserve this place as a safe haven for all wild flora and fauna!

Seasons and Weather

The seasons in Shiga Kogen are quite different from those in the city

In spring, nature awakens all at once, and the entire highland is filled with the breath of life. Then come the refreshing breezes of early summer, followed by vivid blue skies stretching across midsummer days. The dazzling colours of autumn foliage arrive next, gradually giving way to the crisp air of winter, which brings with it the excitement and energy of the ski season.
 
Each season offers a unique kind of beauty and calm — something you won’t find in the big cities. Click to see the details!

What to Wear/Bring

Since you’ll be spending time in nature, it’s best to wear clothes you don’t mind getting a little dirty. The key to outdoor clothing is layering. For seasons other than winter, flexible and stretchy trousers are ideal. Choosing breathable and quick-drying fabrics will help keep you comfortable even when you sweat. Winters can be colder than you might expect, so please come well-prepared. Click to see the details!

From April to mid-May

While temperatures begin to rise in the cities and some days may even feel warm enough to break a sweat, Shiga Kogen remains quite chilly due to its high elevation. Warm clothing is essential. A down jacket may not be necessary, but we recommend dressing as warmly as possible.

From mid-May to early June

Although temperatures are gradually rising, a light jacket is still essential.

From June

As the rainy season begins, be sure to bring rain gear. For hikers a two-piece (jacket and trousers) rain set is especially useful.

From mid-July to late September

As temperatures rise, short sleeves are fine during the day but we recommend carrying a lightweight long-sleeved shirt to protect yourself from sunburn and insect bites.
At this high altitude the sun’s rays are much stronger than at lower elevations – don’t forget your sunglasses, a hat, and sunscreen.

From late September to late October

As temperatures gradually drop, the autumn foliage begins to move down the mountains. With the dry air, some days may feel quite chilly. We recommend wearing layers to adjust to the changing conditions.

From November to March

Once the snow begins to fall, visiting in light clothing is no longer advisable. In particular, cotton jeans are not recommended for the winter season, as they absorb moisture, become heavy, and dry slowly. Be sure to prepare not only a proper winter jacket, but also warm accessories such as a thick hat, gloves, and socks. For snowy conditions, waterproof and thermal boots are highly recommended.

 

Things You Can Do on Your Own

Scenic Spot Hunting
