Stated: JR East first aimed at the 2020 Olympics but could not proceed "due to environmental assessment needs", then "targeted fiscal year 2029, then pushed this back to fiscal year 2031".

JR East's Haneda Airport Access Line Opens to Tokyo Station
The new line runs from a station between Haneda's Terminals 1 and 2 through an underwater tunnel to the Tokaido Main Line near Tamachi, tying the airport directly into Tokyo Station and Shin-Kiba. Construction began on 2 June 2023 and the East Yamanote route is costed at about 280 billion yen.
- The Haneda Airport Access Line is a commuter rail line under construction by JR East linking Haneda Airport to central Tokyo, with a planned opening in "JFY 2031 (tentative)" - the pin's 1 April 2031 is the first day of that Japanese fiscal year rather than a date the article gives[1]
- "Construction began on 2 June 2023" with a groundbreaking ceremony[1]
- "As of July 2024, JR East plans to open the line in fiscal year 2031 with direct through services to Tokyo Station and Shin-Kiba Station; a third through service to Osaki and Shinjuku is also planned"[1]
- "Construction is estimated to cost about 280 billion yen (2022) (equivalent to 297.14 billion yen or US$1.96 billion in 2024)"; the article attaches that figure to the construction as a whole rather than to the East Yamanote route specifically, as the pin does[1]
- The line is heavy rail, two tracks, 1,067 mm gauge, 1,500 V DC overhead, running between Tokyo Station (tentative) and Haneda Airport New Station[1]
- The East Yamanote route runs from the new airport station between Terminals 1 and 2 to a point near Tamachi Station, using an unused freight line between Tamachi and Tokyo Freight Terminal to reach the Tokaido Main Line (Ueno-Tokyo Line), giving through service to Tokyo, Ueno and the Takasaki, Utsunomiya and Joban lines; Tokyo Station to Haneda is estimated to fall from 28 minutes to 18 minutes[1]
- The Coastal Area Route connects Tokyo Freight Terminal to the Rinkai Line for Odaiba and the Tokyo waterfront, with future through service to the Keiyo Line, cutting Haneda to Shin-Kiba from 41 minutes to 20 minutes; the West Yamanote Route connects to Oimachi Station and through-runs with the Saikyo Line to Osaki, Ebisu, Shibuya, Shinjuku and Ikebukuro, cutting Shinjuku to Haneda from 43 minutes to 23 minutes[1]
- The article says three routes are under construction from Tokyo Freight Terminal onwards, but carries a clarification tag from April 2025 asking which routes were actually selected and are now being built[1]
- The plan's history: JR East set out the aim in 2013, released a fundamental construction plan in 2014 proposing an about 5 km new section from the Tokyo Freight Terminal to a new airport station via an underwater tunnel, missed its original target of opening a portion for the 2020 Summer Olympics because of environmental assessment needs, launched the assessment in 2019, and in 2021 announced ministry approval for the East Yamanote route intending to start construction in 2022 for completion by 2029 - two years earlier than the current plan[1]
- In April 2024 plans were altered to preserve part of the Meiji-era Takanawa Embankment discovered in 2023, moving the new line's starting point 100 metres south toward Shinagawa[1]
