Announcement of partial disruption to train services on Saturday, November 16th, 2019

This announcement is to inform you that due to construction work being carried out by the East Japan Railway Company (JR East) on the tracks at Shinagawa Station as part of the development of Takanawa Gateway Station, some train services will be suspended from the last train on Friday, November 15th, until the first train on Sunday, November 17th.
Because of this, there will be widespread disruptions on the Yamanote Line (between Osaki, Shinagawa and Ueno) and on the Keihin–Tohoku Line (between Shinagawa and Tamachi). For more information, please check the official JR East website at the link below.
We advise guests coming to Maxell Aqua Park Shinagawa on this date to allow extra time for their journey.
