The scenery that unfolds before your eyes and the general atmosphere of the entire view are summarized by this word keikan&sbquo or "scene." Scenic nature&sbquo vegetation&sbquo mountains and rivers&sbquo and seasonal scenery are all called keikan&sbquo stemming from the standpoint that they are views that can be appreciated topologically. From the standpoint of artificially created scenery&sbquo however&sbquo keikan is the visually comprehensible scenery as well as the color and emotion carried by the scenery. That is&sbquo the emotional interpretation of the word keikan is the most appropriate term to express everything relating to the environmental atmosphere within the relationship between daily living and nature and the seasons. For example&sbquo natural scenes are keikan (scenes)&sbquo but when it comes to the artificial keikan of a city&sbquo it becomes a word that can express an environmental view that captures the flavor of the time and even consciously reflect economic trends. In classical literature&sbquo it is said that the word scenery (keshiki) was derived from a word that originality meant "emotional color" (keshiki with a different Chinese character) but did not include the "moods" that people emotionally experience. However&sbquo people scene mood from visual impression. In particular&sbquo if you feel some emotion when viewing a scene that involves a relationship between two people or a person and an object&sbquo you can say that you are viewing a scene that can be called emotional scene (jokei). Similarly&sbquo when the scenery is structured with natural creations or arrangement or contrasts between artificial objects&sbquo or when you feel its light and shadow metaphorically or directly&sbquo we tend to call the scene kokei&sbquo or "optical scene." Kokei consists of yin and yang and expresses light and shadow. In the interpretation of a given scenery&sbquo in the japanese language&sbquo words associated with keikan include kokei (optical)&sbquo fukei (atmospheric) and jokei (emotional). This contemporary keshiki-kan (scenic interpretation) may be a phrase to turn keshiki-kan (which is a subjective theory of feeling&sbquo an interpretation of atmosphere) into an objective impression. The very act of designing is to plan scenery with atmosphere&sbquo which is keikan.
