Abstract
This article reports on the results of a survey conducted from the perspective of lifestyle and daytime and nighttime lighting environments that serve as a background when considering health. Tokyo area residents were surveyed via an internet questionnaire in December 2007. The results showed that residents are home in different patterns and thus have different lighting and dimming needs depending on age, presence of children, and other lifestyle parameters. The results implied that, going forward, the lighting environment will need to be controlled in a flexible manner depending on lifestyle.
