To enable stable and efficient production of hydrogen. A hydrogen production apparatus according to an embodiment includes an electrolytic unit and an electrolysis power controller. The electrolytic unit produces hydrogen by electrolyzing steam using electric power supplied from an electric power source. The electrolysis power controller controls the supply of electric power from the electric power source to the electrolytic unit. Here, the electrolysis power controller determines whether an unsupplied time during which electric power from the electric power source to the electrolytic unit is not supplied exceeds a predetermined set time, and starts the supply of electric power from the electric power source to the electrolytic unit when the unsupplied time exceeds the set time.
