国会議事堂
The original story featured four fairies. Sekizawa felt four was unnecessary and trimmed the members to two, feeling that two fairies was manageable. The original story had the Shobijin stand at 60 centimeters but Sekizawa felt the size was too big and would create difficulties when building the sets. One of the original ideas had one of the Shobijin fall in love with one of the leads, however, Sekizawa dropped this idea because he felt it would have required many twists and turns and would had taken time away from Mothra. Originally, Mothra was to cocoon herself on the National Diet Building but Sekizawa felt it wasn't "spectacular enough" and changed the setting to Tokyo Tower.
