A hot spring sento that's very popular with local geriatric set in this hard working waterfront Osaka neighborhood. The two baths are on the first and second floors and change between men and women. Only the second floor bath has a rotenburo, in composition the first floor has a very large salt sauna. Make sure to check out the dangerous looking key for the door to that sauna. Large signs along the side of the walls here tout the "１００％天然温泉" in the baths. Only the cold water and carbonated baths are not filled with the spring water here. The effect of the spring water on your skin will become apparent a few minutes after getting out of the bath. In the water there is a slight slipperiness to it and a slight ferrous smell to the slightly brown tinted very hot water. The main deep bath is billed as a "flowing bath" and is always spilling over the granite walls that keep it in. In the corner are two awesome sunflower style jet baths. I also liked how many great places there were to sit in and out of the baths. I came here with my 2 year old and found that keeping an eye her was very easy but the water a bit too hot for a long bath.
