Colopl Inc. won the Grand Prix at the Japan Generative AI Award 2025, as eight projects were recognized for advancing the use of generative AI across entertainment, business operations and public services.
The awards, announced on December 26, 2025, and now in their second year, are presented by the General Incorporated Association Generative AI Japan in partnership with Nikkei Business. A panel of experts evaluated submissions based on implementation quality, impact, governance and long‑term potential.
Colopl earned the top prize for “Tsukuyomi: The Divine Hunter,” a game built around a proprietary AI system developed with creator Kazuma Kaneko. The title has generated more than 1.6 million unique cards since launch, a scale judges said signals the emergence of a new genre of “generative games.”
Shift Inc. received a Special Award for integrating generative AI into disability employment programs, a move that increased productivity by 70 percent and enabled employees to take on tasks previously considered too complex.
Shippio Inc. was also honored for its multi‑layer AI agent system used in global logistics, which automates up to 90 percent of routine work while keeping humans in the loop for high‑difficulty operations.
Five organizations received Excellence Awards. Digital Hollywood Co., Ltd. was recognized for Ututor, an AI learning partner that evaluates creative work and guides students through skill development.
Machida City Office in Tokyo was honored for its AI Navigator platform, designed to accelerate the rollout of AI‑enabled government services.
Nakahara Works Co., Ltd. was cited for using generative AI to support business succession by analyzing manufacturing data and highlighting technical strengths.
Mitsubishi Electric Digital Innovation Corp. received recognition for an AI‑powered service that assists pharmacists with medication counseling and record creation, developed with mediLab Inc.
NEC Corp. was honored for company‑wide AI‑driven process reengineering, including a decision‑making system that cut cycle times by more than 96 percent.
Organizers said this year’s winners reflect a shift toward practical, high‑impact AI deployments across industries, from entertainment to public administration, as generative AI becomes increasingly embedded in daily operations.
