Hidetaka Miyazaki is born in Shizuoka Prefecture, Japan. Details of his early childhood remain relatively private, but it's known he grew up in a relatively poor family.

Miyazaki developed a love for reading fantasy books and manga, compensating for the limited access to other forms of entertainment due to his family's financial situation. This fueled his imagination and storytelling sensibilities.

Miyazaki attends Keio University in Tokyo, graduating with a degree in social sciences. This demonstrates his interest in understanding societal structures and human behavior, which may subtly influence his game design.

After graduating, Miyazaki begins his career at Oracle Corporation as a network engineer. This seemingly unrelated experience provides him with a foundation in technology and project management, crucial skills for game development.
