The Tokyo Express was the name given by Allied forces to the use of Imperial Japanese Navy ships at night to deliver personnel, supplies, and equipment to Japanese forces operating in and around New Guinea and the Solomon Islands during the Pacific campaign of World War II. The operation involved loading personnel or supplies aboard fast warships (mainly destroyers), later submarines, and using the warships' speed to deliver the personnel or supplies to the desired location and return to the originating base all within one night so Allied aircraft could not intercept them by day.
