『Castle Unite! Oshirobots』: AR Oshirobot Matsumoto Castle Appears at Matsumoto Yamaga FC Home Game Venue in Collaboration with Matsumoto City Tourism & Convention Association

MIXI Inc. (Shibuya-ku, Tokyo; CEO: Hiroki Kimura), through its original content 'Castle Unite! Oshirobots,' will implement a project in collaboration with the Matsumoto City Tourism & Convention Association and Matsumoto Yamaga FC. This project will feature the appearance of 'AR Oshirobot Matsumoto Castle' at the match venue for the Meiji Yasuda J2/J3 Centennial Goal League 'Matsumoto Yamaga FC vs. Fujieda MYFC,' held at Matsumoto Yamaga FC's home stadium 'Sunpro Alwin' on Sunday, May 10, 2026. 'Castle Unite! Oshirobots' has been working to create new regional experiences by collaborating with castles across Japan, fusing anime, digital technology, and real-world experiences. In the case of Matsumoto Castle, ongoing collaborative projects have been developed in partnership with the Matsumoto City Tourism & Convention Association. This current initiative further expands these efforts, implementing a stadium-based project in cooperation with Matsumoto Yamaga FC. In this project, by scanning the QR code on a trading card distributed upon entry, 'Oshirobot Matsumoto Castle' will appear in AR within the stadium, allowing visitors to enjoy photo opportunities and more. Additionally, a 'Castle Unite! Oshirobots' booth will be set up inside the venue, offering limited edition acrylic keyholders, muffler towels, and Goshuin (castle stamps) themed after 'Oshirobot Matsumoto Castle' for sale, along with novelty giveaways. By providing an experience that blends sports viewing with tourism and entertainment, using the stadium as a stage where many visitors gather, the aim is to promote regional charm and encourage visitation. ■Comment from Matsumoto City Tourism & Convention Association Matsumoto Castle is a cultural asset symbolizing Matsumoto City, a 'regional story' that has been passed down through many generations over a long period. We believe that by expressing this story in a place that symbolizes contemporary Matsumoto, such as the Matsumoto Yamaga FC home stadium, it will create an opportunity for people of different generations to share the same experience. We hope that a day of watching soccer will expand into time spent experiencing Matsumoto's history and culture, making Matsumoto a more familiar city to visitors. 'Castle Unite! Oshirobots' will continue to work on creating new experiential value by collaborating with castles and regions across Japan. ■AR Oshirobot Matsumoto Castle appears in the stadium Date: Sunday, May 10, 2026 Location: Sunpro Alwin (5300 Kamibayashi, Matsumoto City, Nagano Prefecture 390-1243, within Matsumoto Daira Wide Area Park) How to Play: Upon stadium entry, 'Oshirobot Matsumoto Castle' trading cards will be distributed.
