The building was originally commissioned by the Japan Iron and Steel Federation as a demonstration of structural steel engineering.
It is one of the few remaining major interior structures from the 1970 expo that retains its original architectural shell.
The pavilion houses an expansive model that depicts the entire 1970 fairgrounds layout, allowing for a top-down visualization of the historical site.
The building's design features industrial materials that were considered cutting-edge in the late 1960s to showcase Japanese manufacturing prowess.
The EXPO '70 Pavilion is housed within the former Steel Pavilion, an original structure preserved from the 1970 Japan World Exposition. It functions as a specialized museum documenting the historical significance, architectural planning, and cultural impact of the Osaka Expo. The interior preserves the mid-century modern industrial aesthetic of the original building while displaying artifacts from the event. Visitors can view a collection of photographs, models, and historical documents detailing the construction of the Sun Tower and the broader expo site. It provides context on the theme 'Progress and Harmony for Mankind' which defined the 1970 event. The facility serves as a focal point for understanding the urban development of Suita and the surrounding park grounds.
