What this is
Seibuen Amusement Park transforms into a GeGeGe no Kitaro playground for summer 2026, marking the second collaboration with the anime film The Birth of Kitaro: The Mystery of GeGeGe. Visitors can tackle puzzle-solving games, ride attractions with exclusive newly recorded voice content from the film's cast, play festival carnival games like Nezumi Otoko's Secret Ball Toss and Mizuki's Shooting Challenge, and order collaboration food menus. Newly drawn illustrations of Kitaro's Father and Mizuki in jinbei festival wear give the event a distinctly summery yokai-matsuri feel, and there's a steady stream of collectible rewards — random coasters with menu orders, illustration cards with merchandise purchases, and a Mini Mini Acrylic Stand Set for puzzle participants.
Who should go
GeGeGe no Kitaro fans of any age, particularly those who saw the 2023 film. Families with children will find the carnival games and collectible merchandise especially appealing, and figure collectors will want to budget for the ¥2,000 merchandise spend threshold to unlock illustration cards.
Good to know
Seibuen Amusement Park is a mid-sized retro amusement park directly accessible from Seibuenchi Station on the Seibu Shinjuku Line — about 40 minutes from Seibu Shinjuku Station. Park entry tickets are purchased at the gate or via the official Seibuen website; foreign credit cards are generally accepted at the main ticket booth but carry cash for in-park stalls and festival game booths. The collaboration merchandise booth is likely to sell out popular items on opening weekends, so arriving at park open is advisable if you want specific goods. Random coasters and illustration cards cannot be chosen, so manage expectations around completionist collecting. The puzzle-solving game trail is self-paced and works well as a structured way to explore the park.
