The purpose of this research is to examine the relation between the direction of benches and sitting behaviors in a street. An observational investigation that targeted public users, and an evaluational experiment by subject were conducted, and the following aspects became clear. 1. The number of people who sat on benches was larger when the benches were arranged face to face than when they were arranged back to back. This was especially remarkable in users for a short time. The reason was assumed to be related to accessibility from the street to the benches. 2. The number of men who sat on benches was larger when the benches were arranged back to back. On the other hand, the number of women who sat on benches was larger when the benches were arranged face to face. 3. Behaviors such as eating and drinking were observed more frequently when benches were arranged face to face. Subjects reported that they felt that people sitting on benches back to back were annoyed by pedestrians.
