In Japanese politics, bribery and corruption occur from time to time. In a recent case, Tsukasa Akimoto, an up-from-the ranks Diet member of the Liberal Democratic Party and former state minister in the Cabinet Office in charge of integrated resorts businesses, including the introduction of casinos to Japan, was arrested on Dec. 25 for allegedly taking ¥3.7 million in bribes from the Chinese gambling company 500.com.

The casino-related bribery scandal did not stop with Akimoto's arrest, either. Mikio Shimoji, a Diet member of Nippon Ishin no Kai, also admitted to receiving a ¥1 million bribe from an adviser of the same company. Four other LDP lawmakers were suspected of receiving money from the company, including former Defense Minister Takeshi Iwaya.

Diet members are representatives of the people, and are able to exert political influence over lawmaking processes and certain businesses and industries. Needless to say, they earn decent wages.
