What FM NACK5 does
FM NACK5 (株式会社エフエムナックファイブ) is a privately held commercial FM radio station (株式会社エフエムナックファイブ) established on March 2, 1988, and headquartered in the JACK Omiya building in Saitama City, Saitama Prefecture, Japan. It broadcasts over the air at 79.5 MHz with 5 kW output from its main transmission site at Iimoritouge (飯盛峠) in Tokigawa-machi (都幾川), and operates a relay station in Chichibu at 77.5 MHz. Its licensed broadcast footprint covers Saitama Prefecture in full along with parts of Tokyo, Kanagawa, Chiba, Gunma, Tochigi, and Ibaraki, reaching roughly 1 metropolitan area and 6 prefectures of the Kantō region. The station has been operating an Emergency Earthquake Rapid Report (緊急地震速報) relay service since April 1, 2008, as part of a nine-station Tokyo commercial radio consortium.
The core product is the live FM broadcast, which carries music (J-POP, anime, and genre-spanning programming), talk shows, news, traffic and weather reports, sports, and cultural content, anchored by a roster of named personalities including TOKIO member Matsuoka Masahiro (松岡昌宏) and Suzuki Masayuki (鈴木雅之). Around this core, the station maintains a multi-channel digital presence: official website streaming, podcasts, the radiko internet radio platform (with a ¥385/month premium tier extending nationwide access), Twitter/X, Facebook, YouTube, and a LINE official account. Two wholly-owned subsidiaries extend the content and commerce stack — 株式会社NACK5ミュージック (NACK5 MUSIC, est. 1998) handles music copyright management, master-recording production, and broadcast program planning; 株式会社NACK5プロジェクト (NACK5 PROJECT, est. 2009) operates the Trima e-commerce marketplace, produces programs, and provides hometown tax (furusato nozei) support services to local governments.
Revenue is generated primarily through radio advertising — time-based commercials (タイムCM) and spot commercials (スポットCM) — with supplementary, non-disclosed revenue from the subsidiaries' music rights and e-commerce activities. The company is led by Representative Director Chairman Naoshi Kataoka (片岡 尚) and President Akira Mutoh (武藤 昭), with Moriuchi Tatsuji (森口 達治) serving as Head of the Broadcasting Department. With 29 employees recorded as of March 31, 2020 and ¥800 million of registered capital, FM NACK5 operates a lean, privately held, advertising-funded regional radio business with no parent company and no disclosed external investors.

FM NACK5 competitors and assessment
Company assessmentDirect peers
- TOKYO FM: TOKYO FM (Tokyo FM Broadcasting Co., Ltd.) is the flagship station of the Japan FM Network (JFN), the same network FM NACK5 belongs to. It broadcasts across the same Kanto region with overlapping advertiser base, music-and-talk format, and JFN syndicated content — making it the closest direct comparable in coverage and business model.
- FM Yokohama: FM Yokohama (84.7) is a Kanagawa-based JFN member FM station operating in FM NACK5's overlapping broadcast region. Shares the same JFN network affiliation, similar advertiser profile, and parallel music-and-information programming format.
- J-WAVE: J-WAVE is a Tokyo-based commercial FM station targeting a similar urban, music-oriented listener demographic in the Kanto region. It competes for the same advertising dollars and premium on-air talent, with an analogous music-and-lifestyle programming format.
- bayfm: bayfm78 is a Chiba-based JFN member FM station broadcasting in the same Kanto market as FM NACK5, with overlapping advertiser base and similar music-and-talk programming. Operates with comparable scale and JFN-affiliated content syndication.
- InterFM: InterFM is a Tokyo-licensed FM station broadcasting in the Kanto region with English-language and music programming. Competes with FM NACK5 for both listeners and Tokyo-area advertising revenue, particularly among commuter and digital-savvy demographics.
Regional players
- CROSS FM: CROSS FM is a Fukuoka-based JFN member FM station with a comparable music-and-talk format and ad-supported regional business model. Useful for benchmarking FM NACK5's regional broadcaster economics outside the Kanto market.
Broad incumbents
- FM802: FM802 is a major Osaka-based commercial FM station and JFN member with a comparable music-driven format and advertising-led business model. Useful comparable for FM NACK5 in terms of regional FM economics and revenue mix, despite the different geographic market.
- ZIP-FM: ZIP-FM is the flagship JFN station in Nagoya and a well-established regional FM broadcaster with a music-heavy format. Comparable to FM NACK5 in JFN membership, business model, and operational scale, though operating in a different regional market.
- TBS Radio: TBS Radio is a Tokyo-based terrestrial radio broadcaster with established Kanto reach, talk-and-information programming, and digital distribution (radiko, podcast). Competes with FM NACK5 for Tokyo-area advertisers and overlapping commuter/listener segments.
- Nippon Broadcasting System: Nippon Broadcasting System (Radio Nippon) is a major Tokyo-based AM broadcaster with a large Kanto audience and diversified digital distribution. While AM rather than FM, it competes for the same Tokyo-area advertising budgets and listener share as FM NACK5.
