Hyakkaou Private Academy
Type: Private Academy
Location: Japan
Status: Active
Overview
Hyakkaou Private Academy is one of Japan's most prestigious schools. Unlike ordinary academies, academic performance holds little value compared to one's ability to gamble.
Within its walls, gambling determines nearly every aspect of student life. Wealth, reputation, influence, and even personal freedom can all be won—or lost—through games of chance and skill.
Students from influential political, corporate, and wealthy families attend Hyakkaou to develop the negotiation, risk assessment, deception, and leadership skills expected of future leaders.
History
Founded to educate the children of Japan's elite, Hyakkaou gradually evolved into a unique institution where gambling became the primary method of evaluating talent.

Games may involve money, favors, status, personal possessions, or specially agreed conditions between participants.
