East Japan Railway Co. said Tuesday a robotic guide utilizing artificial intelligence and an unstaffed convenience store will feature at a new station slated to open in Tokyo in April 2020. JR East hopes to make Takanawa Gateway Station on the Yamanote Line a model for its future stations by using cutting-edge technology, officials said. The new station is expected to attract many visitors because a public viewing site will be established there for the 2020 Tokyo Olympics and Paralympics. The robot and digital signs will provide station information in four languages: Japanese, English, Chinese and Korean. The station will also employ autonomous patrol and cleaning robots on a trial basis until September next year.
