Karuizawa Toy Kingdom is a family-oriented theme park in Tsumagoi Village, Gunma Prefecture, where visitors can enjoy a wide range of toys, attractions, and outdoor activities. Surrounded by the beautiful natural environment of Mount Asama, the expansive park offers something for everyone from infants and young children to adults.
The park features indoor play areas filled with toys, outdoor athletic courses, amusement rides for children, and a variety of hands-on experiences. With so many ways to play and explore, Karuizawa Toy Kingdom is like a treasure chest of fun and discovery for the whole family.
Karuizawa Toy Kingdom is divided into three main areas: the Toy Room Area, Attraction Area, and Athletic Area. Many of the indoor toy rooms can be enjoyed with admission to the park, making them especially convenient for families with young children.
The indoor facilities offer a wide selection of toys, including popular character toys, educational toys, and building blocks. Children can freely touch and play with the toys while developing their imagination and creativity. Since many of these activities are indoors, they can also be enjoyed regardless of the weather.
One of the park’s most popular attractions is Wakuwaku Great Adventure Forest, an expansive athletic course considered one of the largest of its kind in the northern Kanto region. The area features approximately 120 athletic elements that make use of the natural terrain.
Unique attractions incorporate natural lava from Mount Asama, creating an adventurous setting unlike a conventional playground. Tree houses, a giant mushroom-shaped secret base, suspension bridges, and a swing on a cliffside are among the features that encourage children to explore and challenge themselves.
Because the course allows visitors to move and play actively in the forest, it can be enjoyed not only by children but also by parents and other adults looking for an outdoor adventure.
The park has numerous Toy Rooms where children can freely play with different types of toys. There are rooms based on popular characters, as well as areas featuring educational toys designed to encourage creativity and imaginative play.
Mer-chan’s House opened in 2024 to commemorate the 25th anniversary of Karuizawa Toy Kingdom. It is the only facility of its kind in the Kanto region where visitors can experience the world of the popular Japanese doll Mer-chan, which has been loved by generations of children.
Through pretend-play activities such as caring for the doll, children can enjoy imaginative play while learning about kindness and consideration for others.
Tomica & Plarail Land is especially popular with children who enjoy toy cars and trains. Visitors can build their own railway layouts, run toy trains, and play with miniature Tomica cars.
Children can create their own towns, roads, and railway networks, encouraging them to use their imagination while constructing their own miniature worlds.
At the Sylvanian Families House, visitors can enter a charming world populated by the beloved animal characters of Sylvanian Families. A large-scale diorama recreates the characters’ world, while dolls, houses, and miniature accessories are available for imaginative play.
The setting gives children the feeling of stepping into a storybook and creating their own stories.
At Licca-chan House, visitors can take photos with a life-size Licca-chan figure and enjoy activities such as dressing dolls and playing with them. The facility also features special displays that cannot be seen elsewhere, making it an appealing destination for fans of Licca-chan.
