Why has the sauna boom arrived? The story behind the boom

Why has the modern sauna boom occurred?

Let’s consider why saunas have recently gained attention. Once established as a “hobby for older men,” the image of saunas has drastically changed in recent years, attracting popularity among many young people and women. This shift is due to increased media exposure and a heightened awareness of health. For modern individuals, especially, saunas offer a new value as a means to refresh and relieve smartphone fatigue and daily stress.

Moreover, since saunas were first introduced to Japan during the 1964 Tokyo Olympics, the boom has evolved through several phases. Currently, the unique experience of “tuning in” has become a topic of conversation, and various facility types have emerged. This situation, where many people are enthusiastic, can be said to have taken root as a culture rather than being a passing trend.

Such changes are more than just a trend; they have grown to influence people’s daily lives. So, what allure does this sauna boom hold? Let’s unravel its secrets.

The background and evolution of the sauna boom

Saunas have experienced several booms in Japan and are now beloved by many. Where does this popularity come from? Here, we explore how saunas have been accepted in Japan and continue to be supported.

Historical background: From the first introduction to the first boom

The 1964 Tokyo Olympics were the catalyst for the spread of saunas in Japan. The sauna facilities brought by the Finnish team became a hot topic and were introduced by many media outlets. During this period, Japan was experiencing a period of rapid economic growth, and people had the leisure to try new entertainment and health methods. However, this first boom did not last long, as the image of saunas as something “enjoyed by older men” was strong, and it did not penetrate much among the younger generation.

The second boom: Health consciousness and relaxation effects

In the 1990s, saunas gained attention again, this time being reevaluated for their value as a health-conscious and stress-relief method. Particularly in urban areas, they began to be used as a valuable relaxation space for working people and gradually spread to the general public. From this time, saunas became associated with health buzzwords like “detox” and “anti-aging,” and information promoting their appeal increased.

Reasons for the modern sauna boom

So why is there such an unprecedented sauna craze involving the entire society today? Let’s look at some possible factors.

Media exposure and image transformation

The first factor is the increase in media exposure. Saunas, previously perceived as “older men’s culture,” have seen a significant image change due to active promotion by celebrities and influencers. Many famous athletes and actors have declared themselves “sauna enthusiasts” and talked about its benefits, spreading interest among younger generations.

Daily use as a countermeasure for smartphone fatigue

Additionally, saunas are gaining attention as a countermeasure for the modern societal issue of smartphone fatigue. For modern people who frequently look at smartphone and PC screens in daily life, saunas are valued as a place for “digital detox,” where they can refresh both mind and body.

The “tuning in” phenomenon and its psychological effects

The term “tuning in,” which is often heard recently, is also a supporting element of this trend. “Tuning in” refers to the deep relaxation state that occurs after a series of hot and cold baths. This sensation is expected to not only reduce stress but also enhance new ideas and concentration. This unforgettable pleasure once experienced is said to draw many people in.

The new form of private saunas

Furthermore, under the influence of the COVID-19 pandemic, private-type facilities have become popular due to concerns about close-contact spaces. They are supported for allowing safe use while avoiding contact with others, and more users are enjoying them as their personal favorite spaces.

Future prospects: The potential for cultural establishment

Besides the factors mentioned above, there are movements towards tourism resource development and regional revitalization both domestically and internationally. Initiatives towards creating synergistic effects with hot spring areas through collaborations between local governments and companies are also becoming more active. There is even a prediction that this is not merely a passing trend but will deeply root itself within Japanese culture.

In summary, the ability to provide positive impacts on both physical and mental aspects is the biggest factor. This trend is still evolving, making it an exciting theme for the future. It is important to find a style that suits oneself and enjoy it for a long time. It is important to find a style that suits oneself and enjoy it for a long time.
