History
On January 4, 1953, Futo Izu, the then president of Kumamoto Nihon Shimbun, proposed the establishment of a radio station, which was unanimously agreed by those present.[8]: 24 At 6:10 a.m. on October 1 of the same year, Kumamoto Prefecture’s first private radio station, Radio Kumamoto (ラジオ熊本), funded by Kumamoto Nihon Shimbun, officially started broadcasting. The first program broadcast was "Farm House Time".[8]: 24 Radio Kumamoto achieved a profit of 510,000 yen in the first half year of broadcasting. At that time, the Japanese private broadcasting industry was generally in a deficit within 3 years of broadcasting, which was very rare.[8]: 24–45 By 1955, Radio Kumamoto had successfully repaid all debts since its broadcasting, and achieved a profit of 52 million yen.[8]: 25 In the early days of broadcasting, Radio Kumamoto was located on the third floor of the old building of Kumamoto Niichi Shimbun.[8]: 26 But with business expansion and preparations for broadcasting television, Kumamoto Broadcasting decided to build a new headquarters. In 1957, Kumamoto Broadcasting purchased land near the Kumamoto Electric and Communication Bureau of the Electric Corporation, and began construction of the second-generation headquarters in May 1958.[8]: 26 In order to start broadcasting on TV, Radio Kumamoto also increased its capital to 150 million yen in 1958.[8]: 27 At the end of March 1959, the second-generation headquarters of Radio Kumamoto was completed, with three floors and a total floor area of 4,848 square meters.[8]: 27–28
At 8:50 a.m. on April 1, 1959, Radio Kumamoto officially began to broadcast TV programs. It was also the second TV station and the first private TV station in Kumamoto Prefecture after the NHK Kumamoto Broadcasting Station.[8]: 28 At that time, there were only about 30,000 TV sets in Kumamoto Prefecture.[8]: 27 Shortly after the broadcast started, Radio Kumamoto participated in the broadcast of the wedding of Crown Prince Akihito (the current emperor) and Michiko Masada.[8]: 27 From the beginning of the broadcast to September 1961, Radio Kumamoto's daily broadcast time was divided into two periods, day and night, with a break in between. At that time, there were no television stations in neighboring Saga Prefecture, but RKK's television signal could be received in most areas. Therefore, the people of Saga Prefecture asked RKK to set up a branch in Saga Prefecture to broadcast news from there. And Kumamoto Radio also opened the Saga branch in June 1960,[8]: 28 and continued until 1974 when the number of TV stations receivable in Saga Prefecture increased.[8]: 35
In 1961, in order to reflect the reality that television business gradually surpassed broadcasting and became the company's main business, Radio Kumamoto changed the company name to the current Kumamoto Broadcasting, but the initials remained unchanged.[8]: 29 In 1963, 10 years after starting, the number of employees of Kumamoto Broadcasting increased from 49 at the beginning to more than 200, and its profit also increased to 198 million yen.[8]: 30 In October 1966, Kumamoto Broadcasting began broadcasting color TV programs.[8]: 30 In 1967, Kumamoto Broadcasting's TV division joined the TBS television network.[8]: 31 In April 1971, Kumamoto Broadcasting established a branch in Yatsushiro City to strengthen news gethering and advertising business capabilities in southern Kumamoto Prefecture.[8]: 32
On April 7, 1972, the RKK Hall funded by Kumamoto Broadcasting was completed. The building has one floor underground and eight floors above ground, with a total floor area of 4,778 square meters and a total construction cost of 400 million yen. The various subsidiaries of Kumamoto Broadcasting work here.[8]: 33 In 1973, Kumamoto Broadcasting's report on the Taiyo Department Store fire won the JNN Award.[8]: 34 In the same year, Kumamoto Broadcasting also broadcast the Minamata Disease Court Judgment.[8]: 34 In the mid-1970s, Kumamoto Broadcasting promoted business diversification, established subsidiaries such as RKK Development, and entered various industries such as real estate and travel.[8]: 34 At the same time, Kumamoto Broadcasting introduced a complete two-day weekend system in 1975, making it the fifth private radio and television station in Kyushu to achieve it.[8]: 35

The building has three floors, with a total floor area of 1,617.75 square meters. The first floor is a TV studio, the second floor is an office, and the third floor is a radio recording studio.[8]: 38 In 1992, Kumamoto Broadcasting and Kumamoto Kenmin Television (KKT) co-produced the program "Here is RKKT" (こちらRKKT, the name being a combination of both RKK and KKT), creating an innovative case of mutual cooperation between local private TV stations.[8]: 41 In 1996, Kumamoto Broadcasting opened its official website.[8]: 43
