The Museum’s History and Predecessor
The predecessor of Osaka Science Museum was the Osaka Municipal Electricity Science Museum, which opened in 1927. It was Japan’s first science museum and also the country’s first facility to introduce a planetarium. For many years, it played an important role in introducing the fascination of science to the public.
The museum stands in Nakanoshima 4-chome, an area with an important connection to Japanese scientific history. The former Osaka University Faculty of Science was once located here, and physicist Hideki Yukawa, Japan’s first Nobel Prize winner in physics, developed ideas related to his meson theory in this area.
The site is also known as the place where Japan’s first astronomical radio observations were conducted.
Hands-On Exhibits and Science Shows
Osaka Science Museum features more than 200 interactive items in its permanent exhibition areas. Rather than simply viewing displays, visitors can operate and experience many of the exhibits themselves, making it possible to learn scientific principles through direct experience.
Science shows are also held regularly, providing entertaining demonstrations that help visitors discover the excitement of science.
In 2008, the exhibition areas were renovated. One of the highlights introduced at that time was a reconstructed model of Gakutensoku, regarded as the first robot in the East when it was created in 1928.
The museum also has a shop selling science books and merchandise, as well as a café where visitors can take a break.
The Evolution of the Planetarium
The planetarium at Osaka Science Museum has undergone several renovations as projection and digital technologies have advanced.
In February 2022, the museum introduced an immersive full-dome visual system combining MediaGlobeΣ SE from Konica Minolta Planetarium with SkyExplorer from RSACosmos. It also installed GTZ380 projectors manufactured by Sony.
These upgrades provide sharper and more immersive images, allowing visitors to enjoy a realistic journey through the universe.
Rare Scientific Collections
Osaka Science Museum houses a wide range of valuable scientific materials and historical equipment.
The collection includes a Carl Zeiss II planetarium projector, one of the earliest planetarium systems introduced in Japan; a Cockcroft-Walton accelerator once used at Osaka University; materials related to Seimitsukyoku, regarded as Japan’s first chemical research institution; and electrical measuring instruments and electrical equipment dating from before World War II.
The museum also has an extensive collection of popular astronomy books and magazines. Its collection is considered one of the largest of its kind in western Japan.
Exploring the Museum Floor by Floor
4th Floor: Space and Its Discovery
The fourth floor focuses on space and the discovery of the universe. Exhibits cover the solar system and other astronomical subjects, as well as the history of science in Osaka and the development of science from ancient times through the early 20th century.
3rd Floor: Chemistry in Everyday Life
The third floor introduces the chemistry found in everyday life. Exhibits explore minerals, gemstones, crystals, plastics, fibers, crude and synthetic medicines, and the science of smell.
This floor also has a library area and hosts regular science shows.
2nd Floor: Science for Parents and Children
The second floor is designed for parents and children to enjoy science together. Interactive exhibits explore subjects such as the movement of balls, wind, mirrors, and sound.
1st Floor: Electricity and Energy
The first floor serves as the museum’s entrance level and features Gakutensoku, regarded as the first robot in the East.
The floor contains numerous exhibits related to electricity and energy, allowing visitors to explore how different forms of energy work and how they are used in everyday life.
Basement 1: Exhibits and Planetarium
The basement level features original scientific materials and models, as well as the planetarium.
Inside the planetarium, visitors can experience an immersive journey through space using the museum’s advanced visual and projection systems.
