NIJIN Academy Koto-Ojima Campus (2-40-5 Oshima, Koto-ku, Tokyo) will hold a limited-time summer programming school for elementary school students called "3-Day Intensive Summer Break! Original Reaction Game Creation Course" for three days each from August 5 (Wed) to 7 (Fri), 2026, and August 21 (Fri) to 23 (Sun), 2026. This course is a 3-day project-based program where children will create an "original reaction game" that requires them to quickly press keys in response to instructions displayed randomly on the screen. Children will use the same basic mechanism to create unique works, choosing their own themes, characters, rules, and presentation styles for games such as the "Red Flag White Flag Game," a DDR-style rhythm game, a ninja training game, and an "animal whack-a-mole" game. With a small class size of up to 4 students, the program is open to children new to programming as well as those with experience in Scratch or programming. On the final day, students will present their completed works and create short promotional videos for their creations, solidifying their summer learning and sharing it with the world. ◼️ Why This Event is Being Held Summer break offers children more free time, but many parents express concerns such as "my child spends too much time playing games or watching videos" and "I want them to have an experience that contributes to their growth." On the other hand, games are a familiar and engaging presence for children. Therefore, thinking about "how games work," "what rules I would set," and "how to make it more fun," rather than just playing games, can be a catalyst for developing programming thinking and creativity. At NIJIN Academy Koto-Ojima Campus, we value children learning through their interests. This summer school uses "games," something familiar to children, as the subject matter, allowing them to experience planning, creation, arrangement, and presentation over three days. From "Summer of Playing Games" to "Summer of Making Games
