[5][6] As a response to this, Seibu Holdings was founded on February 3, 2006, with the aim of restructuring the group following an investment of ¥100 billion from the American private equity firm Cerberus Capital Management.

[11] After Cerberus abandoned plans to sell a 15.5% stake of the business, however, shares began at the lower offering price of ¥1600 when they were relisted on April 23, 2014.

Consequently, Seibu Holdings attained the highest market capitalization of any Japanese company which owns a private rail network.

Statistics released by the company for fiscal 2013 state that its railway network serves 1.7 million people daily resulting in an annual revenue of ¥140.7 billion.

Formed in 1956, the chain caters largely for the Japanese tourism market with fifty hotels within the country but also has a limited number of overseas resorts in Hawaii, Taiwan and Malaysia.
