The big bath tub used for bathing in the VIP room of Japanese soup is actually a traditional bath tub in the famous "bathhouse culture" in Japan, called "of Uro".
In Japan, Ofuro is considered as an important culture and lifestyle. People usually have a small bathtub at home to take a bath, relax and relieve fatigue. In some high-end Japanese hotels or hot spring hotels, they will specially prepare some large Ofuro for VIP guests.
These VIP Ofuro are generally made of natural wood, which can keep warm and keep the bath water warm and comfortable. Moreover, wood also has good hygroscopicity, has a good moisturizing effect on the skin, and makes people feel more comfortable and relaxed.
Therefore, the big wooden barrel Ofuro is not only a part of Japanese daily life, but also a culture and lifestyle they admire and an important part of Japanese hot spring culture.
