Evolution of Japanese Sauna|Transition from Showa to Reiwa

The Journey of Japanese Sauna Culture

Sauna culture in Japan has undergone a unique evolution from the post-war period to the present. It began in the 1950s with facilities inspired by Finland. Later, the sauna brought by the Finnish team during the 1964 Tokyo Olympics became a hot topic, leading to Japan’s first sauna boom. This period coincided with the high economic growth era, attracting many people to saunas as a new form of relaxation.

As the era shifted from Showa to Heisei, Japanese saunas developed distinctiveness beyond mere imitation. By the Reiwa era, the refreshing effects on the mind and body, known as “tuning,” gained attention, sparking a new boom. These transitions are supported by the unique sensibilities and technologies of the Japanese, leading to diverse facilities and services. Today, their creativity is recognized internationally. Japanese sauna culture will continue to evolve and integrate into people’s daily lives.

The Origin and Introduction of Saunas in Japan

Japanese sauna culture has undergone many changes to reach its current state. It is said that the first sauna appeared in Japan in 1957 (Showa 32). During this time, Japan was in the post-war reconstruction period, exploring new lifestyles. Initially, saunas were directly introduced from Finland, but later, Japan’s unique creativity was added.

The Tokyo Olympics and the First Sauna Boom

The 1964 Tokyo Olympics had a significant impact on the spread of sauna culture in Japan. The sauna facilities used by the Finnish team in the Olympic Village were reported by the media, sparking interest in their effects and usage among many people. This event triggered the first sauna boom, leading to the opening of numerous facilities nationwide. However, during this period, the image of saunas was often associated with “endurance contests,” limiting the user base.

High Economic Growth and the Second Boom

From the 1970s to the 1980s, Japan’s economy experienced rapid growth, bringing changes to people’s daily lives. During this time, interest in health and relaxation increased, and saunas began to be incorporated into new forms such as super sento and spa facilities in urban areas. This made it easier for women and young people to use, leading to the second boom.

The Unique Evolution of Japanese-Style Saunas

At this stage, Japanese sensibilities and technologies were incorporated, giving rise to elements of “Japanese-style.” Methods of presentation not found abroad, such as humidity control and healing music, were adopted, creating diverse ways to enjoy saunas. Additionally, elements like “cold baths” and “outdoor air baths” became popular, bringing saunas closer to their current form.

Saunas as a Source of Healing in Modern Society

Since the 2000s, saunas have increasingly been recognized as a unique Japanese method of stress relief. As indicated by the term “tuning,” they are also increasingly valued as a form of meditation experience. This trend is driven by the demand to temporarily disconnect from digital devices in an always-connected information society.

New Developments in the Reiwa Era

In recent years, saunas have been actively utilized in regional revitalization projects, such as hot spring area redevelopment, in collaboration with local governments. Additionally, since the COVID-19 pandemic, the market for home equipment that can be enjoyed at home has expanded. Meanwhile, on platforms like SNS and YouTube, enthusiasts actively exchange information and introduce events. These trends suggest that saunas will continue to evolve and diversify.

Influence Abroad and Future Prospects

The Japanese-style spa, now attracting worldwide attention, is backed by not only rich natural resources (such as hot springs) but also the diligent and delicate Japanese temperament. This makes it difficult for other countries to imitate, serving as a point of differentiation. However, if further technological innovations are made through international exchange, the potential for the future seems limitless.

In summary, reviewing the above points helps deepen the understanding of the historical background and current position of Japanese sauna culture, fueling expectations for further development. We should continue to watch over its evolving charm.

When Did Saunas Originate in Japan?

The origin of saunas in Japan dates back to the 1964 Tokyo Olympics when the Finnish team introduced them. During this period, full-fledged sauna facilities were established, and sauna culture spread throughout Japan. In fact, similar bathing methods like “steam baths” have existed since ancient times, but the modern sauna culture became widespread following the Olympics.

How Has Japanese Sauna Culture Evolved from Showa to Reiwa?

Since the 1964 Tokyo Olympics (Showa 39), sauna culture rapidly expanded nationwide against the backdrop of high economic growth. At that time, the dominant high-temperature, low-humidity dry saunas had an image of being “tough” or “endurance contests.” However, in recent years, diverse types of facilities and relaxation effects have been re-evaluated, gaining popularity among not only men but also women and young people, marking the third boom.

What New Types of Saunas Are Currently Gaining Attention?

Recently, new types such as “cube saunas” are gaining attention. These have different shapes and concepts from traditional saunas, evolving to meet diverse needs. Additionally, the Finnish steam generation method known as “Löyly” has been adopted, providing relaxation and health benefits to many people.

Who Was the First Person to “Tune” in Japan?

There are no exact records, but according to the ‘History of Japanese Saunas,’ Finnish-style saunas already existed in Japan before the war, suggesting that people experienced “tuning” back then. Although specific individuals cannot be identified, this historical background has become a subject of deep interest and research today.

What Is the Recently Talked About “Third Boom”?

The third boom refers to the resurgence of interest around 2019. The manga ‘Sauna Road’ and its TV drama adaptation have attracted interest from younger generations, and information sharing on SNS has made it popular. This boom emphasizes comfort and design in facilities, strengthening its appeal to new audiences.

Tell Us About the Relationship Between Japan’s Unique Bath Culture and Modern Saunas.

The ancient “steam bath” is deeply connected to Japan’s unique bath culture. Traditional methods like “kara-buro,” where heat generated by burning wood in a cave is used for bathing, have been the foundation. Evolving from this historical background, Japanese saunas have integrated Western (Finnish) styles to reach their current form.

The Evolution and Significance of Sauna Culture

Japanese sauna culture has uniquely developed since its introduction from Finland in the 1950s. The first saunas in Japan were embraced during the post-war reconstruction period as part of a new lifestyle. Later, the sauna brought by the Finnish team during the 1964 Tokyo Olympics became a topic of interest, sparking Japan’s first sauna boom. During this time, many facilities opened, and people were captivated by saunas as a new form of relaxation.

In the 1970s and 80s, the second boom arrived alongside high economic growth, with saunas being incorporated into super sento and spas in urban areas. This movement made it easier for women and young people to use saunas, establishing the unique “Japanese-style.” Elements like “cold baths” and “outdoor air baths” were also introduced, creating diverse ways to enjoy saunas.

Since the 2000s, saunas have been re-evaluated as a stress relief method, with the refreshing effects on the mind and body, known as “tuning,” gaining attention. In the Reiwa era, saunas contribute to regional revitalization projects and the home equipment market has expanded, allowing enjoyment at home.

Through these transitions, Japanese sauna culture is internationally recognized. Facilities rich in creativity, utilizing Japanese sensibilities and technologies, are attracting attention from abroad. The culture will continue to diversify in the future.
