Each of Japan's key commercial TV stations has distinctive traits, though in terms of programming these distinctions are probably insignificant to the average viewer, especially when you often have the boy band Arashi appearing on two or three different stations in the same evening.
The exception is TV Tokyo, which belongs to the smaller TVX network and is affiliated with the Nihon Keizai Shimbun, Japan's premiere financial daily. TV Tokyo has its share of dumb dramas and pointless variety shows but is recognizable for its focus on economic matters. Its nightly news show, World Business Satellite, is arguably Japan's best, even if the business focus necessarily narrows its news scope.
Other economics-oriented series on TV Tokyo include "Cambrian Palace," a business trends talk show with novelist Ryu Murakami; "The Rubicon Decision," which dramatizes notable business successes; and "Dawn of Gaia," a business-related documentary series. Many of the station's most enduring variety shows have money on the brain, too, like the antique assessment show "Nandemo Kanteidan" and the Tokyo neighborhood exploration series, "Admatic Paradise."
