The park is built inside the site of the former Komoro Castle, which is notable for being one of the few 'low-land' castles in Japan where the castle grounds are located below the level of the surrounding town.
The park features a vintage 1960s-era carousel that remains a centerpiece of the amusement area.
Some of the stone walls surrounding the park date back to the early 17th century, providing a contrast to the modern playground equipment.
The zoo section includes a facility for visitors to observe various small mammals and birds common to the Nagano prefecture region.
The site is designated as a part of the Kaikoen historical park, which is famous for its extensive cherry blossom displays in spring.
Komoro City Children's Amusement Park is situated within the historic ruins of Komoro Castle, also known as Kaikoen Park. The facility features vintage amusement rides including a carousel, small Ferris wheel, and battery-operated cars. It incorporates a small zoo that houses animals such as monkeys, owls, and goats, focusing on interaction with smaller species. The park integrates traditional Japanese garden landscapes with recreational infrastructure for children. It occupies a portion of the former castle grounds, surrounded by stone walls and deep moats. The location is known for its blend of Edo-period history and mid-20th-century recreational style.
