Busta Shinjuku Bus Terminal, Shinjuku Station, Tokyo

Shinjuku Station handles more daily passengers than any other rail station in the world, with Guinness World Records crediting it with roughly 3.5 million travelers a day across JR East, Odakyu, Keio, Toei, and Tokyo Metro lines. The highway bus terminal on its south side, officially Shinjuku Expressway Bus Terminal and known locally as Busta Shinjuku, opened in April 2016 to consolidate coach routes that had previously departed from scattered curbside stops around the station. The four-story facility can handle more than 1,600 buses a day, linking Tokyo to destinations across Honshu. It sits atop the Shinjuku Station South Gate building, integrating long-distance bus service directly with the rail concourses below.
