Due to popular demand, the event will be held again in 2025 at Mitsui Shopping Park LaLaport MITSUI OUTLET PARK nationwide.
This event will feature a variety of fun and educational content about space and the moon, centered around an interactive "space Shops" where parents and children or friends can work together to take on challenges.
Within the world of Space Brothers, you can experience the excitement and challenges of space development by taking on missions through trial and error.
