REINS stands for Real Estate Information Network System and refers to the standard information system for real estate distribution.It was established by Japan's Ministry of Land, Infrastructure, Transport and Tourism to streamline brokerage contracts in real estate transactions, and it is operated across the country's four designated regions: East Japan, Chubu, Kinki, and West Japan.

It is available to registered member real estate companies, and it consolidates detailed industry-only information such as properties for sale, closing prices, and transaction terms.After a brokerage agreement is signed for a property, registration with REINS is required under Japan's Real Estate Brokerage Act in certain cases, including exclusive brokerage and exclusive right-to-sell agreements.
