This name was decided upon after consideration by the "(Provisional Name) Shimotsuke Smart Interchange Area Council," which is composed of Shimotsuke City and other entities, and based on a proposed name that took into account the opinions of the Road Signage Improvement Committee, which is composed of road administrators in Tochigi Prefecture, and was officially decided upon by the Japan Expressway Holding and Debt Repayment Agency through the prescribed procedures.
