Company Description

Ubisoft is composed of over 20,000 talented people located in 55+ development studios and offices across the globe. With more than 80% of our teams dedicated to creation, Ubisoft is the biggest in-house creative force in the industry.

Based in Osaka, Japan, the studio formerly known as Digital Kids was acquired by Ubisoft in 2008. Since then, the studio has accumulated extensive development experience across console, handheld, and mobile platforms.
Ubisoft Osaka developed "South Park™ The Fractured But Whole™" in collaboration with Ubisoft's San Francisco studio, and now produces AAA-level titles such as "Rocksmith+" and " XDefiant".
In the future, the company plans to leverage its close working relationship with Ubisoft San Francisco to expand the size of the studio while focusing on the development of further AAA projects.

Ubisoft’s worldwide network of video game development studios and business offices work hand-in-hand each day to deliver rich and innovative gaming experiences that reflect the creativity and diversity of their teams. This cross-studio collaboration model means every team member has the opportunity to participate in challenging projects based on iconic brands including Assassin's Creed®, Tom Clancy's Rainbow Six Siege®, Tom Clancy's The Division®, For Honor®, Rabbids®, Rayman®, Watch Dogs®, Far Cry®, The Crew®, Just Dance® and more. Ubisoft is a global leader in the video games and entertainment software industry.

Ubisoft is committed to enriching player’s lives with original and memorable gaming experiences. We create worlds where people can express themselves, explore and discover new possibilities. 


Ubisoft Osakaは、もともと日本のゲーム開発会社であるデジタルキッズをUbisoftが2008年に買収したことで誕生しました。その後、Ubisoft San Franciscoスタジオと共同で『South Park™ The Fractured But Whole™』を開発し、現在では『Rocksmith+』や『XDefiant』といったAAA級タイトルを制作しています。今後は、Ubisoft San Franciscoスタジオとの緊密な協力関係を活かし、スタジオの規模拡大と共に、さらなるAAA級タイトルの開発に注力していく予定です。

Ubisoftは世界中にある開発スタジオと、ビジネスオフィス同士のネットワークを大切にしており、他国のスタジオと共同開発を行う形式(クロススタジオモデル)を採用しています。この開発モデルならではの、チームの多様性や創造力が反映された、革新的なゲームの提供を目指しています。また、同モデルにより、開発者各人が、Assassin's Creed®, Tom Clancy's Rainbow Six Siege®, Tom Clancy's The Division®, For Honor®, Rabbids®, Rayman®, Watch Dogs®, Far Cry®, The Crew®, Just Dance®などの著名シリーズの開発に携わる機会があります。Ubisoftは世界のゲーム・エンターテインメント業界を牽引する存在です。
