The publicity from Tama's appointment led to an increase in passengers by 17% for that month as compared to January 2006; ridership statistics for March 2007 showed a 10% increase over the previous financial year. A study has estimated that the publicity surrounding Tama has contributed 1.1 billion Yen to the local economy.[2] In January 2008, Tama was promoted to "super station master" in a ceremony attended by the president of the company and the mayor; as a result of her promotion, she is "the only female in a managerial position" in the company.[3] Her new position has an "office"—a converted ticket booth containing a litter box. In January 2010, railway officials promoted Tama to the post of "Operating Officer" in recognition of her contribution to expanding the customer base. Tama will maintain the stationmaster's job while taking over the new job, and is the first cat to become an executive of a railroad corporation.[4]
