For centuries, Japan’s onsen (hot springs) have been a symbol of healing, relaxation, and cultural tradition. Now, in an innovative leap, a Tokyo-based company has found a way to transform these mineral-rich waters into powder — making it possible to export the authentic onsen experience across the globe.
From Mountains to Powder
The company Le Furo, based in Tokyo, has developed a patented technology known as craft onsen. The process extracts and filters the essential minerals found in hot spring water — elements like iron, magnesium, and zinc — and reduces them into fine powder. This innovation preserves the therapeutic benefits of onsen water without the need to transport heavy, perishable liquid.
CEO Naoki Mita compares the method to preparing espresso: “Just as coffee beans are ground into fine powder, we concentrate the essence of onsen minerals into a form that can be easily reconstituted.”
Unlike many commercial powders sold in stores, which often replicate only the scent or color of hot springs, Le Furo’s formula contains the real natural elements that give onsen their unique healing properties.
Aiming for the Gulf by 2026
The company’s first international focus is the Gulf region, where water is seen as more valuable than oil. Plans are already in motion to open spa facilities infused with Japanese onsen minerals by 2026.
For decades, exporting the real onsen experience was considered impossible due to logistics and hygiene concerns. Now, this breakthrough could allow travelers worldwide to enjoy an authentic Japanese spa ritual without leaving their country.
Tradition Meets Innovation
Japan is home to around 28,000 onsen facilities (Ministry of Environment, 2021), making hot springs a central part of both local life and tourism. They are not just baths, but places of community, wellness, and cultural exchange.
If you’re curious about exploring onsen culture in Japan itself, the Japan National Tourism Organization’s Onsen Guide is a great starting point to learn about bathing etiquette and the best hot spring regions.
This new technology opens the possibility of bringing that centuries-old tradition into modern wellness resorts worldwide. Yet, it also comes at a time when Japan’s onsen towns are struggling with overtourism, highlighting the delicate balance between sharing traditions and protecting their origins.
Why It Matters for Travelers
For wellness enthusiasts and cultural travelers, this innovation could mean:
-
Authentic onsen-inspired spas closer to home.
-
Easier access to Japanese wellness traditions outside Asia.
-
A new trend in global luxury spa experiences.
Still, nothing replaces soaking in a steaming outdoor bath in the snowy Japanese Alps — but for many, powdered onsen may be the next best thing.
