Seibu Holdings, Inc. is a Japanese holding company that primarily owns Seibu Railway, Prince Hotels, and Seibu Bus and its subsidiaries, which are collectively known as the Seibu Group. In total, fifty-three companies across the world are affiliated with the Seibu Group. The company was formed in 2006 to restructure the group after it had come to light in 2004 that the predecessor to Seibu Holdings, Kokudo, had falsified the ownership of its shares in Seibu Railway for over forty years. As of January 2015, Seibu Holdings' share prices exceed ¥2900 and the company has the highest market capitalization of any Japanese company which owns a private rail network. Wikipedia
