Hideki Kamiya is born in Matsumoto, Nagano Prefecture, Japan. His early life and formative years are relatively undocumented in publicly available sources, but he would later express a passion for gaming that drove his career aspirations.

Kamiya joins Capcom, a major Japanese video game developer and publisher. This marks the beginning of his professional journey in the gaming industry and sets the stage for his future influential works.

Kamiya played a key role in the planning of the original "Resident Evil". While Shinji Mikami directed, Kamiya was instrumental in conceptualizing the game's atmosphere, story elements, and initial design, contributing significantly to its success and the establishment of the survival horror genre. He served as a planner, helping to shape the game into a commercial success.

Kamiya directs "Resident Evil 2", a landmark title that cemented the franchise's popularity. He expanded upon the original's formula, introducing two distinct playable characters and branching storylines, resulting in a significantly larger and more replayable game. This achievement established Kamiya as a director with the ability to take existing franchises and propel them to greater success.

Kamiya directs "Devil May Cry", initially conceived as a sequel to Resident Evil. Recognizing the gameplay had strayed from its survival horror roots, Kamiya steered the project in a new direction, creating a stylish action game with a focus on combo-based combat and a gothic aesthetic. "Devil May Cry" defined a new subgenre of action game and launched a very successful franchise.

Kamiya leaves Capcom along with other prominent developers to co-found PlatinumGames (originally Seeds Inc.). This move allowed Kamiya and his colleagues greater creative freedom and control over their projects, ultimately shaping the studio's distinct identity of creating high quality action games.

Kamiya directs "Bayonetta", a spiritual successor to "Devil May Cry" that pushed the boundaries of action game design further. The game is known for its intricate combat system, over-the-top action sequences, and the distinctive character design of Bayonetta herself. "Bayonetta" became a critical and commercial success, further cementing Kamiya's reputation as a master of the action genre and as the flagship IP for PlatinumGames.

Kamiya directs "The Wonderful 101", a superhero-themed action game with a unique gameplay mechanic where players control a large group of heroes that combine into different shapes and weapons. Although critically well-received, it didn't achieve widespread commercial success, but has still remained a cult-classic and shows Kamiya's knack for creativity.

Hideki Kamiya leaves PlatinumGames. The reasons cited were that his philosophy and the directions that the company were taking differed. It's unknown what the next chapter of his career will be, but it marks the end of an era for PlatinumGames.
