An example of the 180° rule that Ozu breaks (Source: Wikimedia Commons)
Ozu shoots in the round in Tokyo Story, positioning the camera in various spaces around a room. While the characters remain in the center of the shot, the viewer can see different sides of the character, even behind their backs. A departure from the "180-degree rule applied in Hollywood" (Dresser 13), the use of 360-degree space has several effects.
By shooting in the round, any feeling of a two-dimensional "stage" is broken. The versatility of a traditional Japanese home is realized by this technique. Through the "movement of sliding screens" (Dresser 19), one can enter a room often from multiple directions. Since the screens can make up the walls of a room, once opened, neighboring rooms can combine in a variety of different ways. This creates new spaces and changes the structure of rooms by sliding multiple screens back and forth. Through the camera, it is almost as if the viewer is allowed open and close different screens around the characters. As a result, the room that the characters are sitting in becomes less of a "stage," and more of a place to explore the different perspectives and positioning of the actors. Through opening these different "screens" around a room, the subtle mannerisms of each character is separately brought into focus from different angles. Therefore, during dialogues, the relationships between family members can be analyzed not just by their words and facial expressions, but through an additional interpretation of their body language as well.
By using 360-degree space, the audience can see half of the character's faces in the first part of the scene, and the other half of the characters faces in the next part of the scene, allowing much more of the narrative to occur in a single room.
No longer regulated to a single master shot and left or right positioning, shooting in the round also allows the audience to identify with each character equally and distinctly rather than having to pick a side of the screen. The balance that comes with exploring the 360-degree space also reflects "nonconfrontational stance of the Japanese" (Dresser 15). Any bias that might be held towards a character is suddenly switched visually in the next shot, when the left and right positioning of the characters is reversed.
Due to the positions of characters constantly changing in each shot, the viewer needs to keep track of all the characters in the room. By having to note where each character is throughout the conversation, this encourages the viewer to actively engage in every scene. Due to frequent changes in positons relative to the viewer, the first way the viewer identifes the characters is through their voice rather than their position. Even if many cuts occur within the same scene, moving the audience from one corner to another, there is no sense of unexpected action. Rather, the pace of the film is established on the flow of words and the subtle nonverbal expressions of the character's within each shot.
