How to use

Squeeze the sachet gently to release the minerals and then discard them. For best results, water should be as warm as possible.

Soak for 10-15 minutes. More extended soaking is just for extra fun. You may notice the bath's effect lasts up to 3 hours.

Take precautions to avoid overheating the water and carefully enter/exit the tub. Do not soak light-colored towels in the bath. Clean the tub directly after use to avoid staining.

For first-timers: Make time to explore this authentic experience. It will be great to use it for about 1 hour before you plan to go to sleep. Get ready for a wonderfully restful sleep.

    Japanese Hot Spring Bath Customer Reviews

    • As an athlete, I always struggled with muscle soreness and fatigue after long training sessions. But ever since I started using this, I've noticed a significant improvement in my recovery time. The minerals in the bath soak penetrate deep into my muscles, soothing soreness and promoting relaxation. I especially love the antibacterial action of the minerals, which keeps me feeling fresh and clean even after a long day on the field. And the best part is that I can enjoy a luxurious hot spring experience right in my own home!

    • I've always been a fan of hot springs and the healing properties they offer. But since I can't always make it to a natural hot spring, I was thrilled to discover Japanese Hot Spring Mineral Bath. This product is a game-changer for anyone who loves hot springs but can't make the trip. The minerals in the bath soak are just as effective as those found in natural hot springs, providing relaxation, detoxification, and rejuvenation!
