Kakuda City Space Tower and Cosmo House is a space-themed attraction in Kakuda City, Miyagi Prefecture. Kakuda has developed its identity as a “town of space”, and this facility is one of the city’s most recognizable symbols.
Visitors can see rocket and satellite models up close, learn about the history of space exploration, and discover technologies used in Japan’s space development programs. Among the highlights are a full-scale H-II rocket model and the 44.9-meter-high Space Tower, which offers panoramic views across Kakuda City and toward the Zao Mountains.
One of the most impressive sights at the facility is the full-scale H-II rocket model, completed in 1990 as part of Kakuda’s project to promote itself as a city opening the way to the space of tomorrow.
The model is approximately 49 meters long and 4 meters in diameter, allowing visitors to appreciate the enormous scale of a launch vehicle from close range.
The H-II was an important Japanese launch vehicle designed and developed as a domestically produced rocket. It had the capability to launch two-ton-class geostationary satellites. Seeing a life-size model makes it easier to understand just how large the rockets used for space missions actually are.
The Space Tower stands approximately 44.9 meters high and was designed to evoke the appearance of a rocket launch structure. It has become one of Kakuda’s best-known landmarks.
The tower’s elevator has also been redesigned with a lunar surface-inspired interior. Simply riding the elevator gives visitors the feeling of traveling into space before reaching the observation level.
From the observation room, visitors can enjoy a 360-degree panoramic view of Kakuda City and the surrounding countryside. On clear days, the Zao Mountains can be seen in the distance.
A telescope and viewing information panels are provided in the observation room, helping visitors identify features in the landscape and enjoy the view in greater detail.
The facility has been updated with several space-themed features designed to make the experience more enjoyable.
On the first floor, the elevator area uses a deep-purple space design to create the atmosphere of outer space. Displays of space suits and photo panels are also available, providing fun opportunities for visitors to take commemorative photographs.
The observation room has been equipped with telescopes and information boards so that visitors can better appreciate the scenery from the top of the tower.
Cosmo House is an exhibition center dedicated to space and space exploration. Inside, visitors can see an actual rocket engine and models of artificial satellites at close range.
The exhibits are organized around four main themes, creating an easy-to-follow introduction to the universe and the technology used to explore it.
The Vastness of Space introduces the mysteries of outer space, including celestial bodies and the immense scale of the universe.
Exploring Space focuses on spacecraft, probes, observation technologies, and the ways humans study distant worlds and celestial objects.
Flying Through Space explains how rockets and spacecraft work, helping visitors understand the basic principles behind space travel.
Opening the Future looks toward the future of space development and presents ideas about how space technology may continue to develop.
The facility also uses a 43-inch video display and multiscreen presentations to provide immersive visual content. These exhibits can make technical subjects easier to understand for visitors who are not familiar with space engineering.
Uchū-kko Terrace opened in 2017 as a learning facility focusing on space and science. It is designed for both children and adults and provides a relaxed environment for independent study and exploration.
The library area contains a wide selection of books about space, astronomy, and science. Visitors can browse the collection freely, making it a useful place for children who want to learn more after exploring the rocket and exhibition facilities.
The space is also suitable for workshops and independent research projects. Families traveling with children can therefore combine sightseeing with hands-on learning.

Kakuda City Space Tower and Cosmo House are located inside Tadayama Park, a green area where visitors can combine a space-themed experience with time outdoors.
A convenient way to explore the facility is to begin with the Space Tower observation room and enjoy the panoramic scenery. Visitors can then move to Cosmo House to learn about rockets, satellites, and the history of space development.
Families and children can finish their visit at Uchū-kko Terrace, where they can browse books, take part in learning activities, or explore their own interests in astronomy and science.
Kakuda is known as a “town of space” because the city is home to the JAXA Kakuda Space Center, an important facility involved in Japan’s space development activities.
Kakuda City Space Tower and Cosmo House provides a more accessible way for visitors to experience this connection with space. Rather than simply looking at rockets from a distance, visitors can stand beside a full-scale rocket model, see space-related equipment and displays, learn about exploration technologies, and look out over the city from a tower inspired by a launch facility.
Kakuda City Space Tower and Cosmo House combines science education, spectacular views, and hands-on sightseeing in a single destination. The enormous H-II rocket model gives visitors a sense of the scale of Japanese launch vehicles, while the Space Tower provides a unique viewpoint over Kakuda and the surrounding mountains.
Cosmo House introduces the universe and space exploration through four easy-to-understand themes, while Uchū-kko Terrace provides books and learning opportunities for children and adults.
For travelers exploring southern Miyagi, the facility offers an unusual opportunity to discover Japan’s connection with space development while enjoying the natural surroundings of Kakuda. It is an especially interesting destination for families, science enthusiasts, and anyone fascinated by rockets, astronomy, and the future of space exploration.
