Discard both your clothes and daily cares and enjoy a time-honoured bathing ritual with Onsen of Japan. For thousands of years, Japanese hot springs (or onsen) have been revered for their relaxing and healing qualities, and this guidebook highlights 140 of the very best places for tourists to visit around the country. Onsen experiences include super sento (similar to large aquatic centres), local bathhouses, ultra-chic spas, forest retreats and whole towns dedicated to onsen. The how-to guide will help you navigate the complex etiquette and customs of communal bathing, and easy checklists let you know what each onsen offers and whether tattoos are accepted. One thing is for sure, taking a bath will never be the same again.
