✨Bathe Like a Shogun: Discover the “Gold Koban Bath Bomb” from the Onsen Box Hakone Edition✨

Ever dreamed of soaking in gold like a feudal lord from the Edo period?
The Onsen Box Hakone Edition sometimes includes a playful and luxurious surprise: the Gold Koban Bath Bomb. Inspired by koban—oval gold coins used in Edo-era Japan—this bath bomb is wrapped in a shiny golden foil and weighs 80g, giving it the look and feel of real treasure.

💛 What Makes It Special?
Drop it into your bath and watch it fizz, releasing fine bubbles and the elegant scent of a Golden Floral Bouquet. The water gradually turns into a rich, golden hue—symbolizing good fortune and celebration in Japanese culture.

🌿 Where Tradition Meets Wellness
Infused with moisturizing ingredients, it leaves your skin soft, smooth, and nourished. The tiny carbonated bubbles also help promote circulation, warming your body from the inside out.

2. Remove the golden foil wrap from the bath bomb.
3. Drop the bath bomb into the water and let it fizz.
4. Soak and relax for 15–20 minutes while enjoying the scent and golden glow.
