[2] The Keikyu platforms are located underground with elevators and escalators to carry passengers to the arrival and departure levels of Terminal 3.

The Tokyo Monorail platforms are located above ground, connected to the third floor of the terminal building.

[2] On March 27, 2010, there was a fire in the station building under construction that burnt an area of approximately 700 square meters (7,500 sq ft) and injured one worker.

[4] On 14 March 2020, both the Tokyo Monorail and Keikyū stations were renamed to Haneda Airport Terminal 3 Station (羽田空港第3ターミナル駅, Haneda-kūkō Dai-san Tāminaru eki) to coincide with the change in the names of Haneda's terminal buildings.

[5][6] Before the changes, two operators used different names for the station in Japanese: The station's provisional Japanese name was Kokusai tāminaru eki (国際ターミナル駅) in Keikyu documents and Kokusaisen tāminaru eki (国際線ターミナル駅) in Tokyo Monorail documents.
