We had been running numerous workshops to create locally character 'Kitamoto KAO project' for 4 years. In this project, the lighting experiments were conducted to adopt the design process based on the human activities. The lighting environment was improved in consideration of abolishing surrounding darkness and walking safety. At the junction in front of the station, this lighting design succeeded in keeping people to avoid various accidents. After the improvement was completed, multiple events the characteristic of the square is visualized have been held.
