In April 2006, the Wayakama Railway converted all the stations on the Kishigawa Line to being unmanned in order to reduce their expenses. This meant that local employees near each station had to be selected to serve as station masters of their respective areas. At the Kishi Station in Kinokawa, a local grocer by the name of Toshiko Koyama was chosen for this position. While working, Koyama adopted several stray cats and fed them at the station. One of these cats was a calico which he named Tama.
In 2007, Tama (yes, a cat) was named Kishi's new station master - she was even given her own tiny conductor's uniform! Her appointment brought immediate publicity to the line and boosted its passenger count by 17% within a year.
Last year, Tama received a promotion! She was named to the post of operating officer for her dedication to customer service on the line. As part of the position, Tama received her own "office" - a renovated former ticket booth at the station. She is now the only female in a managerial position of the company's 36 total employees, and the only feline in history to become an executive of a railroad corporation! She technically holds the 5th highest position in the company! Read more about this crazy promotion.
Tama has her own Wikipedia article as well (quite an accomplishment for a cat) so you can learn more about this remarkable cat.
