WHAT IT IS?
In Okinawa, Japan, the EM Wellness Kurashinohakko Lifestyle Resort has pioneered a unique concept: “Fermented Living”. Fermentation here isn’t just about food … it’s the core philosophy of the hotel. Every element is designed around the power of Effective Microorganisms (EM):
- Probiotic cuisine: kombucha, miso, natto, and full menus crafted to boost gut health.
- Fermented spa treatments: enzyme facials, probiotics baths, and skincare with living cultures.
- Sleep innovation: bedding and textiles infused with microbes to enhance rest.
- Sustainable cycles: composting and waste management through fermentation, closing the loop.

WHY IT´S COOL?
Because it transforms something microscopic into a viral and unforgettable guest experience:
- It taps into Gen Z and Millennials obsession with wellness, gut health, and holistic self-care.
- It blends ancient Japanese traditions with modern biohacking and sustainability.
- It’s purpose – driven: eating, resting, and living in harmony with nature’s smallest allies.
- For young travelers, it’s not just a hotel – It’s a story worth posting

(“Hacco Bath” …. where you can enjoy a rice bran bath heated by the action of microbes fermenting.)
WHY IT HAS FUTURE GROWTH POTENTIAL?
The global market for fermented foods and probiotics is already booming and shows no sign of slowing down, which means hospitality has a huge opportunity to tap into this momentum. At the same time, wellness tourism is growing faster than any other segment, and gut health is quickly becoming its new frontier. What makes the idea even stronger is that it’s scalable: from boutique city hotels offering kombucha tastings to luxury resorts with full-on fermentation retreats, the model can work at different levels.
In other words, fermentation is moving beyond food and turning into a lifestyle movement that the hotel industry can lead.
