Winter 2025: The Silent Spectacle. 3 Reasons Why Okuoi Kojo Station & Sumatakyo Onsen are Best in Winter
It's mid-December, and the cold has truly set in. You might be thinking, "Why go deep into the mountains in such cold weather?"
Actually, winter is when the 'Okuoi' area along the Oigawa Railway is at its most beautiful and luxurious.
While the fresh green and autumn foliage seasons are bustling with tourists, winter is a season for adults to have the "silence" and "spectacular views" all to themselves. Here are 3 reasons why you should visit Okuoi Kojo Station and Sumatakyo Onsen this winter, told by a local enthusiast.
Reason 1: The Air is Clear, Making "Okuoi Blue" Shine
The charm of Okuoi Kojo Station lies in the contrast between the deep green of the dam lake and the red iron bridge. In winter, the air is dry, and there is less dust and humidity, making the visibility surprisingly clear.
- Sky Blue: A piercing winter blue sky
- Lake Green: An emerald green with added depth
- Bridge Red: A vivid red floating on the lake
This three-color contrast provides a vividness you can't experience in the summer haze. Especially from the viewpoint on the opposite shore, the scenery looks crisp like a diorama, making it the best season for photography.
Reason 2: Zero Wait Time at the "Dream Suspension Bridge" & Exclusive Views
Sumatakyo's "Dream Suspension Bridge" (Yume no Tsuribashi) has been selected as one of the "Top 10 Suspension Bridges in the World to Walk Before You Die." During the autumn foliage season, it is not uncommon to see a 1-2 hour wait just to cross the bridge.
However, in winter, the wait time is almost zero. You don't have to rush across while worrying about the bridge's capacity (10 people).
Stopping in the middle of the lake to enjoy the 360-degree view and a quiet moment to yourself. This luxury is a privilege unique to winter when the number of tourists settles down.
⚠️ Note The Dream Suspension Bridge may be closed during strong winds or freezing conditions. We recommend checking the official website of the "Sumatakyo Beauty Hot Spring Tourism Association" in advance.
Reason 3: "Beauty Hot Spring" Soaks into Your Cold Body
And the greatest pleasure of all is Sumatakyo Onsen. The water here is a sulfur spring with a unique viscosity, known as the "Beauty-Making Hot Spring" (Bijin-zukuri no Yu). The slimy sensation that wraps around your skin becomes addictive once you try it.
The happiness of soaking in an open-air bath in the crisp winter air is indescribable. After the bath, your skin will be smooth, and your body will be warm to the core.
Furthermore, since there are few city lights in Okuoi, the winter night sky is filled with starry skies. Staying at a hot spring inn and spending a quiet night looking up at the stars. Is there a better way to spend the end of the year?
Access and Clothing Advice for Winter Okuoi
Preparation is key to enjoying your winter trip.
Clothing: Serious Cold Protection!
The temperature in the mountains can be more than 5 degrees Celsius lower than in the flatlands. Since there is nothing to block the wind on the way to the station viewpoint or the suspension bridge, down jackets, gloves, and scarves are essential. Also, the walking paths may have frost columns or be slippery, so please come in sneakers or trekking shoes with good grip.
Transport: Check Road Conditions
Although it is not typically a heavy snow area, there is a risk of road freezing in the mornings and evenings. If you are coming by car, we recommend wearing studless tires or carrying chains just in case. If you are worried about driving, a wonderful plan is to park your car around Kanaya Station or Shin-Kanaya Station and head there leisurely by Oigawa Railway (train).
Summary: End 2025 in Okuoi
Bustling tourist spots are nice, but how about a trip facing nature in silence this winter? The clear air, beautiful scenery, and warm hot springs will gently heal the fatigue of the year.
Please dress warmly and go visit. It is sure to be a special winter memory that will remain in your heart.
