What Is the Kofu Children’s Support Festa (Let’s Play at the Castle!)?

The Kofu Children’s Support Festa (Let’s Play at the Castle!) is an event organized by Kofu City to provide children with opportunities to enjoy a wide range of hands-on experiences.
The event is held in cooperation with local groups and organizations, including children’s support groups, Ventforet Oshiro Land, and the Kofu Police Station.
The venue is Maizuru Castle Park, which was developed on the former site of Kofu Castle. The event takes advantage of the park’s grassy open spaces to offer outdoor activities, including physical games and opportunities to climb aboard working vehicles that children rarely get to see up close.
