This paper aimed to perceive the relationship between corner planning and nursery program which influenced by children development. We investigated the changing of furniture layout in 2 kindergartens and a nursery school using corner planning for a year. The investigation involved 10 nursery rooms consist of children between 3 to 5 years for the 3 schools. The results were: 1) Nursery room consists of several corners (play corner, living corner, teacher's corner), storage spaces, and blank spaces. 2) Nursery program consists of a long-term program (program for the year) and a short-term program (monthly and weekly program). In long-term, teachers decide the outline of corner planning at the beginning of the year. In short term, the details of corner planning surch as kind, location, size, arrangement of furniture etc. are determined according to the change of children's activities on children development. 3) Corner planning made by teacher is based on development of children. Several independent corners are set up by teachers at the early stage. At a later time, They are connected gradually based on the change of children's activities.
