Japanese Toji Water Therapy: A Soothing Alternative to the Season of Punishing Wellness Trends
Amidst the seasonal onslaught of strenuous rituals, from chugging liters of water to enduring military-grade exercise challenges and icy water plunges, a gentler and time-honored wellness trend emerges. While ice baths have become synonymous with fitness and resilience, driven by the likes of Wim Hof, the Dutch "Iceman," there exists a more serene approach rooted in centuries-old Japanese tradition.
Enter Toji, meaning "hot water cure" – an ancient practice embraced by the Japanese, renowned for their longevity. Unlike the bracing intensity of ice baths, Toji revolves around the therapeutic act of bathing in natural hot springs, known as onsen. Dating back to the 6th century, this practice involves immersing oneself in onsen waters multiple times a day for at least a week, offering a holistic remedy for a spectrum of ailments.
Japanese folklore weaves enchanting tales around the healing prowess of onsens. For instance, Dogo Onsen in Matsuyama, Ehime, has a legend attributing its healing waters to a white heron with a once-injured leg. In Shizuoka's Tokko no Yu Onsen, the hot spring is said to have miraculously gushed forth when the revered 9th-century monk Kobo Daishi struck a rock to cure a sick boy.
Further south, Yonomine’s Tsubo-yu onsen in Wakayama, the world's sole Unesco world heritage-listed hot spring, is believed to have tended to injured samurais post-battle. Even consuming an egg boiled in the hot spring of Owakudani in Hakone is rumored to add seven years to one's lifespan.
Contrary to the arduous endeavors of modern wellness trends, studies show that within three weeks of Toji, participants experience lowered blood pressure and stress hormones. So, as the world grapples with punishing routines, perhaps the serene embrace of Toji offers a more harmonious start to the year, drawing from the wisdom of Japanese longevity practices.
Unveiling the Science of Onsen: A Dive into the Health Benefits Beyond Folklore
While the historic tales surrounding the benefits of toji might verge on the fantastical, there exists a solid foundation of science supporting the health-promoting qualities of onsen bathing. Professor Shinya Hayasaka, a medical doctor and professor at Tokyo City University, delves into the tangible effects of onsen bathing and the age-old practice of toji, offering insights grounded in research.
Studies have shown that within three weeks of toji, blood pressure and stress hormones are lowered. Those who indulge in more than one onsen bath a week exhibit lower LDL and higher HDL cholesterol," asserts Professor Hayasaka. However, a cautionary note accompanies these healthful endeavors – moderation is key. The ideal onsen temperature falls between 38 and 40 degrees, with a warning that temperatures exceeding 41 degrees can elevate blood pressure and induce clotting. The body's response, guided by the appearance of sweat on the forehead, serves as a natural indicator for when to conclude the bathing session.
Beyond the immersive experience, the benefits of onsen bathing extend to oral consumption in areas where it is deemed safe. Some onsen towns feature hot spring drinking fountains known as insenjo, amplifying the mineral-rich content's positive impact on health. Government research, as per the Ministry of the Environment, highlights the potential advantages, with sodium chloride-rich onsen water benefiting those with kidney disease, hypertension, swelling, and hyperthyroidism. Sulfur or carbon dioxide-rich insenjo, on the other hand, may aid in easing diarrhea.
While the luxury of a three-week onsen retreat might be a rarity in contemporary lifestyles, Professor Hayasaka introduces the concept of "shin toji" or "new hot water cure" as a pragmatic alternative. Tailored to fit into modern schedules, shin toji encourages intermittent onsen bathing during day trips or weekend getaways, offering a practical yet healthful twist to traditional practices. In essence, a little onsen bathing, whether steeped in history or adapted for the present, promises a rejuvenating escape for both body and mind.
Savoring the Essence of Onsen: A Healthful Soak in Japan's Tranquil Retreats
Professor Shinya Hayasaka's extensive study involving 11,830 participants unveils the transformative impact of short onsen getaways known as "shin toji." Remarkably, even brief onsen trips left participants feeling positively rejuvenated, with added benefits when combined with complementary activities such as hiking and golfing. Hayasaka's findings underscore the simple yet profound truth: the more frequent the onsen visits, the better individuals tend to feel. Amidst the fervor of new-year health regimens, it serves as a valuable reminder that self-care can be indulgent and need not be a stringent routine.
While multiple trips to Japan's 27,671 onsens may be a distant aspiration for many, Hayasaka offers a comforting alternative – recreating the onsen experience at home. The therapeutic value of raising body temperature during soaking is replicated in warm baths, enriched further with minerals through bath bombs, salts, or the inclusion of baking soda. Hayasaka recommends adding a touch of citrus, specifically the limonine found in citrus peel, for an aromatic and healthful bath experience.
As an ode to the diverse charm of onsen towns, Kusatsu stands out for its iconic Yubatake hot water field, known for its high acidity and sulfur content beneficial for skin and muscles. Yufuin, another gem, entices with a blend of traditional ryokan and modern amenities, with its waters reputed for combating fatigue, muscle pains, and gastrointestinal distress. The picturesque winter scenery enhances the allure of Yufuin, inviting visitors to explore its pedestrianized streets adorned in thick powder snow and don yukatas before immersing themselves in the skin-beautifying onsen waters.
In essence, the onsen experience transcends geographical boundaries, offering a healthful retreat whether nestled in the heart of Japan or recreated within the comforting confines of one's home.
