Overview
Television Kanagawa, commonly branded as TV Kanagawa or tvk, is an independent commercial television station based in Yokohama, Japan. It serves Kanagawa Prefecture and can also be received in parts of the wider Tokyo metropolitan region. The station operates outside Japan’s major national commercial television networks and is a member of the Japanese Association of Independent Television Stations, the industry group commonly associated with Japan’s independent UHF broadcasters. The station emerged from a policy and market environment in which the established Kanto broadcasters concentrated heavily on Tokyo and did not always provide extensive coverage of events and issues in surrounding prefectures. In 1969, the Ministry of Posts issued UHF television licenses for six Kanto prefectures. Twelve prospective operators in Kanagawa consolidated their bids with support from the prefectural government, forming the company that became Television Kanagawa in November 1970. A preliminary broadcasting license followed later that month, and the company was formally established in April 1971. TVK began regular transmission on April 1, 1972. Its initial service used UHF channel 42, later associated with digital channel 18, and its call sign was JOKM-TV during the analog era and JOKM-DTV after the transition to digital broadcasting. The opening schedule combined educational programming, films, local information and youth-oriented evening content. Because many households initially lacked television sets capable of receiving UHF signals, the station distributed 50,000 UHF antennas to help build reception and accelerate audience penetration. By November 1973, its signal reportedly reached 92 percent of Kanagawa Prefecture. Advertising alone proved difficult to sustain in the station’s early years. TVK therefore diversified into related activities, including housing exhibition facilities. It opened TVK Housing Plaza Hiratsuka in 1973 and TVK Housing Plaza Yokohama in 1974. The station also progressively expanded its locally produced programming. By 1975, original programs represented approximately 45 percent of its schedule. Music, sports, local news, entertainment and community-oriented programming became important parts of its identity, helping it distinguish itself from the national and Tokyo-centered networks. The company experienced significant financial pressure during the 1970s and early 1980s. A 25-hour anniversary telethon in 1976 raised 20 million yen in donations, but TVK also recorded a deficit exceeding 100 million yen that year. An advertising campaign aimed at attracting more commercial customers helped return the station to profitability in 1977. In 1980, TVK joined with Chiba Television Broadcasting, Television Saitama and Gunma Television to share selected programming. It later developed additional cooperation with independent stations, using program exchanges and co-productions to broaden its schedule while controlling production costs. A reconstruction program launched in 1982 emphasized commercial operations, advertising sales and stronger sports and music programming. The approach produced improved results in the following year. TVK subsequently extended its broadcast day, strengthened morning original programming and continued developing locally relevant content. It reported record revenue and profit levels toward the end of the 1980s and began paying dividends in 1991. The collapse of Japan’s asset-price bubble and reductions in certain prefectural promotional payments then weakened its financial position. The station returned to profitability in 1996, suffered another period of deficits beginning in 1997 and recovered in 2000. The transition to digital terrestrial television required additional capital and encouraged further operational cooperation with other independent broadcasters. In April 2003, TVK joined Tokyo MX, Television Saitama and Chiba Television Broadcasting in creating Shutoken Net4, a metropolitan-area news-sharing arrangement. Today, TVK remains a regional broadcaster whose identity is built around Kanagawa-focused news and information, entertainment, music, sports and other locally produced or independently sourced television content.
History
Television Kanagawa was created during the expansion of Japan’s regional UHF television system. In the late 1960s, the major Kanto broadcasters were already established, but their coverage was strongly centered on Tokyo. The national licensing policy therefore encouraged prefecture-based broadcasters that could supply local news and information. When UHF licenses were offered for six Kanto prefectures in 1969, twelve groups in Kanagawa sought authorization. With support from the Kanagawa prefectural government, these proposals were consolidated into a single company on November 6, 1970. The company received a preliminary license on November 27 of that year. A founding general meeting was held on April 15, 1971, and Television Kanagawa was formally incorporated on April 20. During the preparation period, Nippon Television and NET Television, now TV Asahi, provided personnel assistance, while employees were sent to Sun Television for operational training. The station also addressed a practical obstacle to UHF adoption: many households did not possess suitable antennas or receivers. TVK distributed 50,000 UHF antennas without charge to interested households. It transmitted a test signal on February 5, 1972, followed by test programming beginning March 5. Regular broadcasting began at 9:30 a.m. Japan time on April 1, 1972. The station initially used UHF channel 42 and became one of Japan’s early commercial UHF broadcasters. Its launch program was titled Habatake TVK. Early programming included educational broadcasts in the morning and films in the afternoon and evening. The station also deliberately targeted younger viewers during evening hours, using a different mix from the established commercial networks. Reception expanded rapidly, reaching an estimated 92 percent of Kanagawa Prefecture by November 1973. TVK’s first operating years were financially difficult because the local advertising market could not by itself support the station’s ambitions. In November 1973 it opened TVK Housing Plaza Hiratsuka, entering the housing-exhibition business, and opened a second facility in Yokohama in July 1974. The station increased its investment in original local programming; by 1975, internally produced programs accounted for about 45 percent of its lineup. A 25-hour fourth-anniversary telethon in 1976 raised 20 million yen in donations, although the company simultaneously faced a deficit of more than 100 million yen. An advertiser-recruitment campaign improved its commercial position, and TVK reported a profit in 1977. The station continued to experiment with programming and partnerships. In 1980, it formed a program-sharing arrangement with the other three independent Kanto UHF stations: Chiba Television Broadcasting, Television Saitama and Gunma Television. A short-lived adult-oriented program, The Adult, was introduced in 1981 but ended after difficulties obtaining suitable films. That year, TVK produced The Distant Crossroads of Civilization for its tenth anniversary; the documentary was sold to other broadcasters, demonstrating the potential of TVK’s production capabilities even while its broader finances remained under pressure. In 1982, management designated the year as the beginning of a reconstruction program. The strategy emphasized stronger advertising and commercial operations, while sports and music programming became increasingly important. The station achieved its strongest profit since launch in 1983. It gradually extended its daily schedule, moving the opening time from 9:30 a.m. to 8:30 a.m. in October 1984 and to 7:30 a.m. in April 1990. Morning programming also shifted away from primarily educational material toward more original broadcasts. By fiscal 1989, revenue and net profit had reached levels sufficient to eliminate accumulated deficits, and TVK began paying dividends to shareholders in 1991. The economic downturn following Japan’s bubble economy affected the station. In 1995, falling advertising conditions and reduced promotional payments from the prefectural government contributed to its first deficit in thirteen years. Although TVK returned to profit in 1996, it experienced deficits for three consecutive years beginning in 1997. Profitability was restored in 2000. The transition to digital terrestrial television then became a major capital requirement. TVK increased its capital in 2001 and again in 2003, while also seeking to limit production costs and improve sales through cooperation with other independent stations. In April 2003, TVK joined Tokyo MX, Television Saitama and Chiba Television Broadcasting in establishing Shutoken Net4. The initiative coordinated news resources and enabled the participating broadcasters to share metropolitan-area coverage. TVK’s digital-era identity continued to combine Kanagawa-specific reporting and community information with music, sports, entertainment, films, educational material and programming acquired or co-produced through independent-station networks. Its analog call sign was JOKM-TV; after digital conversion it became JOKM-DTV, with digital transmission associated with channel 18. TVK remains an active regional independent broadcaster headquartered in Yokohama.
