Tonami Onsen is a soothing hot spring in Tonami city, situated in the broad Tonami Plain of central Toyama Prefecture, famous throughout Japan for its unique scattered settlement pattern where farmhouses stand individually amid their own fields of tulips — making Tonami the country's foremost tulip cultivation region and home to the celebrated annual Tonami Tulip Fair. The bicarbonate thermal waters offer skin-softening and anti-inflammatory benefits, providing a tranquil counterpoint to the vibrant springtime floral spectacle for which the plain is nationally renowned. The flat, fertile landscape of paddy fields and tulip plantations surrounding the onsen gives it a distinctive and genuinely rural Etchū character.
