神 is the general Japanese word for god or deity, used in Shinto, Buddhism, and everyday language. 上帝 is specifically the Chinese supreme deity or the Christian God, and is much more limited in use.
天帝 also refers to a supreme heavenly deity in Chinese mythology, but 上帝 is more directly associated with the ancient Chinese creator god and the Christian God.
From Chinese 上帝 (Shàngdì), literally 'Supreme Emperor' or 'Highest Deity'. The term was adopted into Japanese with the same characters and similar religious connotations.
