Discover Shizuoka's Nuru-yu: The Perfect Summer Onsen Adventure
Discover Shizuoka's Nuru-yu: The Perfect Summer Onsen Adventure
Who says hot springs are only for winter? Shizuoka Prefecture has the perfect solution for onsen lovers who want to enjoy therapeutic waters even during the warmer months. Enter the Nuru-yu Stamp Rally - a delightful summer event that introduces you to the gentle art of "lukewarm" onsen bathing! 🌸
What Makes Nuru-yu Special?
Nuru-yu (ぬる湯) literally means "lukewarm water," referring to onsen with temperatures between 36-39°C - much closer to your body temperature than the typical scalding hot springs. This makes them absolutely perfect for longer, more meditative soaks without the intense heat. Imagine settling into these soothing waters while surrounded by Shizuoka's beautiful mountain scenery!
