Sayama Ski Resort (Tokorozawa City, Saitama Prefecture), operated by Seibu Recreation Co., Ltd. (Head Office: Tokorozawa City, Saitama Prefecture, President: Ryuya Yoda), will hold the "2026 Water Festival" from Saturday, April 25, 2026, to Sunday, September 27, 2026, under the theme "A Sea in Tokorozawa!? Marine Friends Gather!" Building on last year's concept, the "2026 Water Festival" offers five areas to enjoy: the "Thrill Area," "Soaking Wet Area," "Ryugu Castle Area," "Seabed Area," and "Cooling Area," each expressing a new ocean worldview. The inflatable attraction in the "Ryugu Castle Area" has been renewed to the "Turtle Slider." New attractions in the "Soaking Wet Area" are sure to get you wet, such as "Water Fireworks" and the "Surprise Bucket," which maximize the feeling of coolness using water. The "Seabed Area" features a "Ball Pit", allowing even small children to play safely. The "2026 Water Festival" is an indoor theme park where you can have fun in a "cool space" that makes you forget the summer heat. Additionally, during the GW period from the opening day, April 25 (Saturday), to May 6 (Wednesday, holiday), we will hold "GREAT WATERFES ~Great Water Festival~", packed with events related to marine friends such as the "Penguin Day Pen Pen Event ♬" and "Fish Workshop." In addition to visitor benefits and stage shows of various genres, there will also be a participatory content titled "Giant Cardboard Painting" to create the stage background for the Ryugu Castle Area. Furthermore, starting this season, we will also launch a ticket purchase service via the "Seibu Line App." To commemorate this, a limited-time special campaign is also planned. So, this summer, please come to Sayama Ski Resort's "2026 Water Festival" with your family and friends to create summer memories. ~A Sea in Tokorozawa!? Marine Friends Gather~ 《Park Map》
