The present invention provides a hydrogen water production apparatus capable of producing a saturated concentration of hydrogen water efficiently and in a short time with a simple apparatus, a production method thereof, and a storage method for maintaining a high concentration. SOLUTION: A container which can contain water and can be sealed, and a pressurizing unit which pressurizes hydrogen in a gas state contained in the container together with water to 1 atm or more and less than 10 atm as hydrogen pressure in the container. The pressurizing means is a pressure of hydrogen stored in the hydrogen storage container or a mechanical pressure obtained by compressing hydrogen with a pump, and has a connecting pipe for connecting the hydrogen storage container to the container and supplying hydrogen to the container. An apparatus for producing hydrogen water, further comprising mixing means for mixing water in a container and bringing water into contact with hydrogen.
