Tanagura Onsen is a bicarbonate and carbonated thermal spring in Fukushima Prefecture's Tanagura City—known across Japan as Hana no Machi (the City of Flowers), where an extraordinary commitment to public flower planting has transformed the city's streets, parks, and public spaces into a continuous seasonal garden of changing floral color that draws visitors throughout the year. The effervescent, skin-stimulating quality of the naturally carbonated bicarbonate waters provides a refreshing mineral soak that complements the sensory richness of a city defined by its flowers—both the visual pleasure of blooming public gardens and the bubbling animation of CO2-charged mineral water create an experience of lively natural abundance. Bathing in Tanagura's carbonated spring water within the Flower City's landscape combines the geological effervescence of volcanic mineral water with the botanical generosity of one of Japan's most deliberately flowered civic environments.
