A sodium-led chloride spring with 21,573 mg/kg of dissolved solids — exceeding ocean salinity, it falls squarely in the strong-salt class and leaves a thick mineral coating on the skin after the bath. The water emerges at a hot 50.4 °C and reads weakly alkaline (pH 8.0), soft on the skin, while the sensory note pairs a strong salty edge with a faint carbonic tang and a slight iron undertone.

About

The large baths on the 3rd floor, called Aoba-no-yu (青葉の湯), run on the hotel's own natural spring for both the indoor and outdoor tubs. The water has a noticeably salty character. The sauna fires auto-louhu cycles throughout the day, and a chiller-cooled cold bath and cooling chairs complete the setup. Bathing is for guests staying at the hotel.

230. Dormy Inn Sendai ANNEX Dormy Inn in Sendai with a fairly decent onsen for a business hotel. There is massage. It is located not far from the station. The bath photos are from the internet, and they match. Inside, there is a bath with clear water, temperature 41. Breathing inside is fine. There is a sauna. The outdoor bath has no view, and there is a thatched roof above. Late in the evening there was a little lighting, and it felt quite cozy. The water is clear, temperature 40. 06.11.2024 07.11.2024
