"Kur" which means recovery in German and "Bios" which means life in Greek, from the combination of the two was born the name Hotel Kurbio.

We wish for you to feel the sensation of having your body and mind be reborn and bring you back to health. This fresh type of healthy resort was born from that thought.

The provided meals are filled only with the specialty vegetable ingredients. Morning includes organic carrot juice while the afternoon provides a lunch with soup and salad with organic vegetables and whole-wheat strawberry bread. Dinner offers a macrobiotic full course that can add organic beer and wine for an additional charge.

On top of that, we also offer a complete health program that includes nature walks and personal training. We hope you choose your preference that fits with your condition and style.

Alternatively at this hotel located near Kusatsu Onsen is one of Japan's three most famous hot springs, one may experience the all-natural hot springs and detox & refresh oneself to one's heart's content.

A healthy day wrapped in a hush that can't be experienced anywhere but Kusatsu. At this hotel that realizes this dream, why not try to meet a whole new you?

Read more はじめて利用させていただきました。 ホテルのエントランスからとてもリラックスできる雰囲気と新鮮なにんじんジュースで、日頃の疲れを十分癒すことができました。スタッフの皆様の適度な距離感とホスピタリティは素晴らしいと思いました。 何より草津温泉の泉質と大自然を感じられるお風呂がとても良かったです。ただ一つ夏場の半露天風呂には蜂やアブが寄ってくる(特に昼間は)ので、この時期だけでも内風呂も温泉にしていただけると嬉しいなぁと思いました。 でも蜂に好かれてキャーキャー言いながらも、草津の湯を満喫させてもらいました。また是非利用させていただきます。

I used it for the first time. From the entrance of the hotel, I was able to fully relieve my daily fatigue with a very relaxing atmosphere and fresh carrot juice. I thought that the staff members had a good sense of distance and hospitality. Above all, the bath where you can feel the quality and nature of Kusatsu Onsen was very good. Bees and horse flies approach the open-air bath in the summer only (especially during the daytime), so I thought it would be nice if the indoor bath could also be used as a hot spring. However, I was able to enjoy Kusatsu-no-Yu even though I was fascinated by bees. I will definitely use it again.

One of Japan's three famous hot springs, Kusatsu Onsen has seven streams, one of which is the "Bandaiko Stream" from which Hotel Kurbio pulls its water. At this 100% natural hot spring, the front part contains an open semi-outdoor spa. Rare for Kusatsu Onsen is the spacious and open view from the bath. The scenery of Mt. Asama through the trees extends outward. At the semi-outdoor spa (either male or female), Finnish sauna (either male or female), and indoor bath/Jacuzzi (either male or female), why not try detoxing and refreshing both body and mind?

We have prepared an array of programs for guests aiming for health and beauty (reservation required).

◆Nature walking (estimated time: 2 hours/¥3,500)
The staff of Krubio will take you around the lush nature of Kusatsu. The forest can be traversed in Nordic walking style. Nordic walking is a walking style that utilizes 2 poles. Our guides will support you through your choice of "enjoying the forest at a slow pace" or "experiencing exercise at a high pace". Additionally there is a plaza in the middle of the forest filled with bark chips where one may take a break and stretch: where one can still brush shoulders with the trees for a relaxing effect. While enjoying the snowy winter landscape, one may exercise in snow shoes. (shoes used to walk on top of snow. 2 hours/¥4,500~).

◆Personal training (estimated time: 1 hour/¥6,000 one person/¥8,000 pair lesson)
A private lesson with a trainer that molds exercises and stretches with the guest's condition.

◆Esthetic treatment starting with face & body

◆Bowel therapy for heightened fasting effects   etc.

【Famous hot spring+Macrobiotic+Fasting: "3 nights 4 day care plan" overview】
Along with the popular macrobiotics, the other famous characteristic of Kurbio is fasting and is also in the full care plan. If you spend the 3 nights and 4 days entrusting your body to the forest and hot springs of Kusatsu, you too can experience all the stress contained in your body and mind "completely clearing up". Guests who wish to schedule an appointment should contact relux concierge desk (03-6432-4962/Weekdays・Saturday 10:00am〜7:00pm).

〜Contents of Plan〜
■Day 1: One may eat a macrobiotic meal that has the delicious tastes of specialty ingredients.
■Day 2, 3: After a lunch of vegetable-packed soup, the fasting program begins. 。※While fasting, other than the organic carrot juice, lemon, and umeboshi provided in the morning, noon, and night, we have also prepared ginger tea, brown sugar, and a thick sweet ginger beverage called Kuzuyu for you to enjoy at any time.
■Day 4:We prepare a meal that will be gentle on your relaxed colon.

〜What is fasting?~
Fasting is a detox method that rests the digestive system that usually continues working throughout the day by removing meals burdensome to the body, burning fat and removing harmful materials from the body. It is not the same as eating nothing; instead, nutrients necessary to the body are absorbed through juice. To increase by resetting your digestive function, through detoxing, one may hope to effectively diet and decrease weight and body fat.
