large indoor convention space with a stage and a large screen in the distance. A crowd of people is gathered in front of the stage, watching a performance or presentation on the screen. The screen displays a person speaking. There are stage lights of various colors illuminating the scene. A person in a yellow costume with a large, cartoonish head is walking in the foreground. There are metal crowd control barriers nearby. A sign in Japanese indicates "Standing Area Entrance/Exit." The convention space has a high, exposed ceiling structure with crisscrossing beams. The atmosphere suggests a lively, crowded event.
