The best rotenburo in winter
Winter in Japan offers a unique experience: that of immersing yourself in a rotenburo, an outdoor thermal bath, while contemplating a snow-covered landscape. This ancient tradition allows you to enjoy the benefits of natural hot springs while connecting with the country's winter beauty. Let's discover together the best rotenburo to visit during the cold season, their unique features and the precautions to take to enjoy them to the full. Get ready for an unforgettable moment of relaxation in the heart of the Japanese winter.
What is a rotenburo and why enjoy it in winter?
A rotenburo (露天風呂) is an outdoor thermal bath fed by a natural hot spring of volcanic origin. Unlike indoor onsen, rotenburo offer a unique outdoor bathing experience, whatever the season. In winter, they become particularly attractive for several reasons:
Firstly, the striking contrast between warm water and cold air creates an incomparable sensation. Imagine being immersed in water at 40°C, while the surrounding air is well below zero! This thermal shock, known as "yukimi-buro" (literally "bathing while looking at the snow"), is not only pleasant but also beneficial to your health.
What's more, rotenburo often offer spectacular views of snow-covered landscapes. Whether facing snow-covered mountains, beside a frozen lake or in the heart of a frosty forest, the natural setting adds a contemplative dimension to the experience. This communion with nature in winter is deeply rooted in the Shinto religion, which places great importance on harmony with the environment.

Practical tips for enjoying rotenburo in winter
To make the most of your rotenburo experience in winter, here are a few essential tips:
1. Hydrate well: Drink plenty of water before, during and after the bath to avoid dehydration. The heat of the bath and the cold outside can quickly dry out your body.
2. Enter the water gradually: The temperature contrast can be brutal. Start by splashing yourself with warm water (ashiyu) before entering the bath slowly, to avoid thermal shock.
3. Limit your bathing time: Don't stay in hot water for more than 15-20 minutes, especially if it's your first time. Get out if you feel dizzy or nauseous.
4. Bring warm clothes: After the bath, your body will need to warm up quickly. Bring a yukata (light kimono) and warm clothes for after the bath.
5. Follow etiquette: Follow onsen rules of conduct, such as washing before entering the bath and not dipping your towel in the water.
Benefits of outdoor bathing in cold weather
Winter rotenburo are not only a pleasant experience, they also offer numerous health benefits:
1. Stimulation of blood circulation: The contrast between warm water and cold air stimulates circulation, which can relieve muscle and joint pain.
2. Immune system boost: Alternating hot and cold can stimulate the immune system, helping you to better resist winter illnesses.
3. Stress reduction: The combination of relaxing warmth and soothing winter scenery can significantly reduce stress and anxiety.
4. Improved quality of sleep: A warm bath at the end of the day can promote deeper, more restful sleep.
5. Mineral benefits: Thermal waters are rich in minerals beneficial to the skin and general health. Each spring has its own unique composition, offering specific benefits.
