Insider tip — Ogawa Onsen draws warm sodium-chloride water from the deep Kanto aquifer beneath this small traditional town, celebrated for its hand-made washi paper industry dating back 1,300 years. A soak pairs naturally with a tour of the historic paper-making workshops that line the centre of Ogawa-machi, where artisans still pull sheets by hand from wooden frames. The dark mineral water is distinctly warming during the cold winter months.
