An onsen town (onsen-gai) is a town or area that has developed around hot springs, featuring a concentration of inns, ryokan (traditional Japanese inns), restaurants, souvenir shops, and public baths. These towns cater to tourists and visitors seeking to enjoy the therapeutic properties of the hot springs, known as “onsen,” as well as the local culture and natural surroundings.

Key Features of an Onsen Town

1. Onsen Facilities:
   • Onsen towns are home to various hot spring inns, public baths, and day-use onsen facilities, offering a range of bathing experiences.
2. Sightseeing and Strolling
   • Many onsen towns have charming stone-paved streets, footbaths, and local shopping districts, allowing visitors to enjoy a leisurely stroll while taking in the atmosphere.
3. Local Culture
   • Each onsen town has its own unique culture, often reflected in local cuisine, traditional festivals, and historic buildings. The towns are often steeped in history and tradition.
4. Therapeutic Stays (Toji)
   • Onsen towns are not only popular for short-term visits but also for longer therapeutic stays, known as “toji.” This practice involves extended bathing to heal and restore health using the medicinal benefits of hot springs.
