Tokyu Corporation was established as Meguro Kamata Railway, which was separated from Den-en-toshi Company, a residential developer in Den-en-chofu in Ota-ku and Setagaya-ku, Senzoku in Meguro-ku, Ookayama in Ota-ku, Tokyo, established by Eiichi Shibuysawa, who is appearing on the redesigned JPY 10,000 bill, to build and manage the railway (present Meguro Line and Tokyu Tamagawa Line) between Meguro Station and Maruko Station (present Numabe Station). The company has been built and managed eight railway lines, Toyoko Line, Meguro Line, Tokyu Tamagawa Line, Oimachi Line, Den-en-toshi Line, Ikegami Line, Kodomonokuni Line (its infrastructure and carriages are owned by Yokohama Minatomirai Railway), and Setagaya Line. Tokyu Corporation is spinning off its railway business into a newly-established separate company, Tokyu Railways, on September 2nd, 2019, the day marking 97th anniversary of the establishment and 101 anniversary of that of the ancestor of the company.
Because of the unique history, start as the residential developer, Tokyu Corporation has a different management philosophy from the other major railway companies in Japan that the company manages the railway as a part of the infrastructures in the city. Not only residential development, but the company had invited campuses of Tokyo Institute of Technology (Ookayama, Ota-ku, Tokyo), Keio University (Hiyoshi, Yokohama City, Kanagawa Prefecture), Tokyo Gakugei University (Shimouma, Setagaya-ku, Tokyo, moved to Koganei City, Tokyo in the present), Tokyo Metropolitan University (Yakumo, Meguro-ku, Tokyo, moved to Hachioji City, Tokyo in the present) to gather more passengers not only citizens living in the self-developed residential areas. After World War Two, the company has developed a larger residential development in Kawasaki City, Yokohama City, and Yamato City in Kanagawa Prefecture and Machida City in Tokyo Metropolitan Area and had built Den-en-toshi Line. In recent years, the company also pours its efforts for constructing office and shopping buildings such as Shibuya Hikarie and Futako-tamagawa Rise.
As searching why Tokyu Corporation hasn't collaborated with Tomytec, I found that Tokyu Corporation has been awarded as a "Nadeshiko Brand", one of the companies with a positive attitude toward providing the good workplace environment for female employees, by Ministry of Economy, Trade, and Industry and Tokyo Stock Exchange. Among the railway companies, only Tokyu Corporation has been listed for seven years since 2012. Since 1988, Tokyu Corporation has recruited women workers and they have been on railway business since 2001. According to the brochure of company prospectus, Tokyu Corporation achieves a plan for doubling the headcount of women manager by 2020 compared with that in 2014.
Because I heard that several railway companies collaborated with Tomytec employ or recruit no women railway staffs, I see that "Nadeshiko Brand" may be one of the reasons that a "Tetsudou-musume" character on Tokyu Corporation has yet to be unrealised to show its attitude not to rely on an external character.
Between 2005 and 2010, I had filled in the name of Tokyu Corporation many times in the brank for the railway companies to collaborated with Tomytec on online questionnaires.
For many years, it had been said that the railway companies in Kansai Area that Surutto KANSAI stored fare card and PiTaPa smartcard are available hadn't collaborated with Tomytec, but since 2013, Keihan Electric Railway, Semboku Rapid Railway, Osaka Monorail, and Mizuma Railway has collaborated and "Tetsudou-musume" characters are created. Because of that, Tokyu Corporation must be the last stronghold for Tomytec creating "Tetsudou-musume" characters.
