Shinjuku Highway Bus Terminal (新宿高速バスターミナル, Shinjuku Kōsoku-basu Tāminaru) was a bus terminal once operated by Keio Bus, in Nishishinjuku, Shinjuku, Tokyo, Japan. This bus terminal has been closed and replaced with the much larger South exit dedicated bus terminal which houses all companies under one roof and unifies ticketing systems and signage. Previously, each company had their own terminal serving the station.[1] The new terminal, known as Busta for short, is the nation's largest bus terminal.
