Construction Investment Outlook The construction investment outlook has been published annually by the Ministry of Land, Infrastructure, Transport and Tourism since fiscal 1960 with the aim of clarifying the size and structure of the domestic construction market. It estimates the amount of investment based on the volume of all construction activities in Japan. Survey on Construction Works (Fundamental Statistical Survey) This survey has been conducted since 1955 by the Ministry of Land, Infrastructure, Transport and Tourism to clarify actual conditions of construction works and construction industry. The survey is composed of "Current Survey of Orders Received for Construction" and "Statistics on Construction Undertaken". Current Survey of Orders Received for Construction The purpose of this survey is to obtain basic data for construction administration, etc. by ascertaining details of construction orders and the amount of orders received from public institutions and the private sector in detail by orderer, industry, type of construction and region. The survey is scheduled to be conducted as of the end of each month and covers construction work undertaken in Japan by approximately 12,000 contractors selected from contractors with completed construction work in the fiscal year two years before the survey was conducted amounting to 100 million yen or more, according to the scale of the amount of completed work in the Statistics on Construction Undertaken. The results of the survey are restored (population estimation) to the total number of licensed construction companies. The restored population is a list of licensed construction contractors as of the end of the fiscal year two years before the survey was conducted. The estimation method was changed in April 2021.
