Hoshi Ryokan in Awazu Onsen, Komatsu, Ishikawa, is recognized by the Guinness World Records as the world's oldest continuously operating hotel — founded in 717 AD and operated by 46 successive generations of the Hoshi family across 1,300 years, through Japan's medieval wars, Meiji modernization, and World War II, making it the most durable family business enterprise in human history. The chloride-rich thermal waters of Awazu Onsen that have flowed through Hoshi's baths since the Nara period are the same that drew the legendary monk Taicho, who is credited with discovering the spring, and whose wooden hall is preserved within the modern ryokan complex as a shrine to the founding thermal miracle. Staying at Hoshi Ryokan is not merely visiting a hot spring but entering a living institution whose institutional memory spans the Buddhist Nara period, the samurai Kamakura shogunate, the Sengoku Wars, the Tokugawa peace, the Meiji transformation, and the entire modern era of Japan.
