Japan's traditional lifestyle culture centered on hot springs. Since ancient times, onsen bathing (yutoji) has been valued for therapeutic and spiritual purposes. Distinct etiquette governs bathing, including rinsing practices and mixed bathing traditions. With approximately 25,000 natural springs nationwide, each region has developed unique therapeutic traditions. Japan is globally recognized as having the world's most sophisticated hot spring culture.

A belief system established in the Edo period attributing beauty-enhancing properties to specific hot springs. Tamatsukuri and other famous onsen were recognized as 'beauty baths,' popularized through haikai poetry and kabuki dialogue. This belief system promoted development of women-focused cosmetics industries from mid-to-late Edo period, leading to beauty product development specific to onsen regions. It represents an early fusion of tourism culture and commercial capitalism in Japanese history.

Architectural design standard systems established at famous Japanese onsen resorts to maintain townscape coherence. Implemented in Kurokawa, Yufuin, and other locations, they aim to fuse contemporary architecture with traditional aesthetics. These standards function not merely as regulations but as cultural systems forming the aesthetic identity of onsen tourism destinations. The attempt to balance regional character with modernity represents innovative urban planning in Japan.

A process from the Meiji period through mid-Showa wherein traditional onsen beliefs were reinterpreted based on Western medical evidence and systematized as hydrotherapy. Medical analysis of mineral composition, temperature effects measurement, and scientific verification of salt and mineral content transformed onsen efficacy from 'folk belief' to 'medical fact.' This enabled diversification of onsen tourism from luxury resorts to medical-welfare facilities. It constituted pioneering forms of modern medical tourism.
