Keisei Transit Bus

The Keisei Transit Bus Co., Ltd. (京成トランジットバス株式会社) is a Japanese bus company. It was formed by Keisei Bus (Keisei Group) and Oriental Land Company, on 2 February 1999. Keisei Transit Bus has two barns, one in Shiohama Ichikawa, the other in Chidori Urayasu.

History
This company was established in 1999 to transport passengers and staff to the Tokyo Disney Resort by bus.

In 2001, as the bus department of Keisei Electric Railway was split into parent and child companies, the Urayasu Line and Gyotoku Line were transferred to Keisei Transit Bus from Keisei Electric Railway. Simultaneously, the Braki Line and Ōsu Line were transferred to Ichikawa Kōtsū from Keisei Electric Railway. In 2006, Kaijin Line was transferred from Keisei Bus Funabashi Office, giving it a bus route in Funabashi. In 2009, Ōsu Line and Baraki Line were transferred from Ichikawa Kōtsū. This company operated five bus routes thereafter.

Ichikawa Kotsu was renamed Keisei Taxi Ichikawa in 2012. This companies' main operation has been taxis since the bus routes transferred to Keisei Transit Bus in 2009.

This company commenced operating a highway bus route connecting Chōfu Station (Tokyo) and Tokyo Disney Resort in step with Keio Bus. The Ichikawa・GyotokuーHaneda Airport Line was transferred to the company in July 2014.
