Everything you need to know about Japanese onsens

Expect a simple but effective setup: hot water, traditional surroundings, and a chance to escape for a while.

• Skin Benefits: The minerals in the water can improve skin texture, leaving it feeling smoother and more refreshed.
• Detox and Circulation: A session in the onsen promotes circulation and helps the body flush out toxins, making it a solid option for anyone needing to hit reset.
