What is documented, and what is reconstructed?

The 173 m height, 40 storeys, construction dates and May 18, 1992 lift are documented by the building’s official website. The exhibition panel records a 1,040-tonne lifted assembly, four winches, a 150 m lift and approximately seven hours of lifting at 35 cm/min.

The model was authored in Blender using your photographs. Footprints, façade spacing, structural members, cranes and landscaping are visual approximations, not surveyed dimensions. The lifted base is shown separately from the later observatory enclosure. Early tower erection and all animation timing are illustrative; the seven-hour lift is compressed. Surrounding Osaka and the Westin hotel are omitted to keep the construction visible.

The 1988 three-tower proposal is a design concept. This experience reconstructs the two-tower building completed in 1993.
