To provide a method and an apparatus for obtaining reduced water, which has pH within a range of city water standards, has no problem as usual city water even when drunk so much, contains a large amount of gaseous hydrogen and has oxidation-reduction potential of -400 to -550 mV, by a method except an electrolytic reduction method.
An upward open vessel is arranged at an upper part in an pressure-resistant tank, the pressure-resistant tank is filled with the gaseous hydrogen and is pressurized, water is jetted from above the vessel toward a center of an opening to make the gaseous hydrogen involved in the jetted water and to produce foams containing a large amount of the gaseous hydrogen. Thus foam-shaped hydrogen is dissolved in water by pressurization of the gaseous hydrogen in the pressure-resistant tank and a large amount of hydrogen is contained in the water.
