JOOY-DTV, virtual channel 4 (UHF digital channel 16), branded as MBS TV (MBSエムビーエステレビ, Emubīesu Terebī) (formerly Mainichi Broadcasting System Television (毎日放送テレビ, Mainichi Hōsō Terebi) until 23 July 2011), is the Kansai region key station of the Japan News Network, owned by Mainichi Broadcasting System, Inc.


MBS is a core station of the Japan News Network (JNN), with TBS TV as its key station. MBS is a member of the "Five Company Federation" (comprising it, TBS, HBC, CBC and RKB) and is also a major shareholder of TBS Holdings. It distributes G-Guide EPG data, and used to distribute analog G-Guide program data to Tokushima Prefecture, where the only commercial TV station is affiliated to NNN/NNS.

During the 16 years and one month from the start of TV broadcasting until the network affair was resolved, it was a key station of NET (now TV Asahi) and was subsequently affiliated to the All-Nippon News Network (ANN) upon its opening. At the same time, Tokyo Channel 12 (currently TV Tokyo) was also connected to the station.

With the complete transition to digital terrestrial broadcasting on July 24, 2011 , the notation of newspapers and TV information magazines on the same date changed from "Mainichi TV" (or "Mainichi") , which has been used since the start of television broadcasting), to "MBS TV" (or "MBS"). In the terrestrial digital TV G-Guide , it is written as "MBS Mainichi Broadcasting". Until July 23, 2011 , the general name was Mainichi Broadcasting Television , and when it was simply called MBS, in the analog era, it was written as Mainichi TV in the radio and television columns of newspapers.

On April 1, 2017, the trade name was changed to "MBS Media Holdings", and both TV and radio broadcasting businesses were taken over by "(New) Mainichi Broadcasting". After that, on April 1, 2021, "MBS Radio Co., Ltd.", which was newly established as a wholly-owned subsidiary of MBS Media Holdings, took over the radio broadcasting license and business that Mainichi Broadcasting had held, and moved exclusively to television (JOOR-DTV changed to JOOY-DTV).

Among the broadcasting stations in Osaka, the company, Asahi Broadcasting Television, and Kansai Television are three companies that opened earlier than their respective key stations in Tokyo (TBS Television, TV Asahi, Fuji Television). This is because these three companies and the three key stations had nothing to do with each other at the time of their establishment. However, despite being the oldest station in Japan to start radio broadcasting, it was the fourth station in Osaka to start TV broadcasting. It was almost the same time as Asahi (Nippon Educational Television (NET TV) at that time), but it was one month behind. On the other hand, Yomiuri TV and TV Osaka were established with the intention of their respective key stations, so they opened later than the key stations.

It has a strong connection with RKB Mainichi Broadcasting, co-produced and co-sold radio programs, and on television, even during the pre-1975 affair era, Kyushu Asahi Broadcasting (KBC) sold in-house programs that were not organized or sponsored net. , and jointly established a health insurance union, and are presenting aspects of sister companies. In addition, the remote control key ID for analog master stations and digital broadcasting is also "4". It has a close relationship with Mitsubishi UFJ Bank and Resona Bank.

MBS was involved in the establishment of FM802 as a major shareholder along with Nippon Broadcasting System . At the time of its establishment, it was organized by Nippon Broadcasting System, and the person in charge of sales was seconded from Mainichi Broadcasting System. Even now, we often co-host events. In July 2019 , a disaster information sharing partnership agreement was signed between FM802 and FM COCOLO operated by the company.[1]

Corporate information

Main office

Among the TV stations in Osaka, it is located in a busy area, and the front of the head office is also used by commuters on weekdays. In the neighborhood, there are business and commercial facilities such as "Chayamachi Applause" where the Umeda Arts Theater is located , Hankyu Corporation headquarters building, Umeda Loft, NU Chayamachi, etc. The current office building can be seen from inside the trains running between stations and between Osaka Station and Shin-Osaka Station on the JR Kyoto Line. The upper part is shaped like the letter "M". There are some documents that say that the building was modeled on the image of "Mainichi", but at the time NTT's radio frequencies were being transmitted in this airspace, and there were restrictions on the height of the building, this design was chosen.


The current company building was completed on September 1, 1990 on the site of the Hankyu Department Store Distribution Center in Chayamachi, Kita-ku, Osaka. Headquarter functions such as sales and accounting at Mainichi Osaka Kaikan, departments such as the news department at Senrioka Broadcasting Center, and some television and radio programs produced at Senrioka were moved to the new company building in Chayamachi. From the same day, a special program was produced and broadcast for two days on television and five days on radio to commemorate the 40th anniversary of the opening of the station and the start of broadcasting in the new building.

Since the grand opening on the same day, most of the first floor has been used as an "atrium" (open space) for live broadcasting and recording of TV and radio programs and various events. "MBS Goods Shop" (former name was "Mzono Shop" → "Nebula") and a branch of Tully's Coffee (when it opened in 1990, it was a restaurant called "Starship") were also occupied. On the second floor, when it first opened, it was given the function of a concert hall under the name "Galaxy Hall". Later, it was diverted to "Galaxy Studio". It was used for live TV programs, public recordings, and events.

In July 2010, the company announced that it would construct a new building with a base isolation structure of 15 floors above ground and 1 floor below ground on the north side of the head office . Osaka City applied the "Business/University Location Promotion Subsidy Program",[2] and construction began in April 2011 and was completed on September 4, 2013. Along with the new building being named the "B Building", the main building was named the "M building". The names "M Building" and "B Building" are derived from the initials MBS. At the time of the start of operation of the B Building, there is no actual facility or building officially named "S Building".

The B Building had its grand opening on April 4, 2014 at 11:07:09, named after MBS TV's channel number (4) and MBS Radio's frequency (1179).[3]

In the B building, there are two studios for TV programs, offices, heliport, height of about 36m (about 117m above ground), radio towers, etc. In addition, the relay truck depot in Senrioka was also consolidated, and the conventional office building (named "M Building" after the completion of the "B Building") is replaced by connecting corridors on the 2nd, 12th and 13th floors. On April 20, 2015, the main control room (master) was updated to the new master in the B Building.

From 2018, with the 60th anniversary of MBS TV, the second floor of the M Building was renovated as a "live center" for the purpose of responding to live broadcasting and strengthening cooperation between news and production stations . Start construction. After remodeling the space including Studio C (Galaxy Studio) into an "Information Floor" linked to live information programs, it was operated from January 28, 2019.[4][5] In addition, the "Chapla Stage" on the 1st floor of the M Building was also renovated on the premise of incorporating it into the "Live Center".

JOOY-DTV (previously JOOR-DTV)


Data as of the time of the shutdown of analog signals in Japan (July 24, 2011).

About the channel frequency

VHF channel 4 of analog television broadcasting in the Osaka area was originally used by the NHK General station in Osaka. Osaka Television Broadcasting (OTV) (currently Asahi Broadcasting Television, channel 6), which had already been established, and Daikansai Television Broadcasting (currently Kansai Television Broadcasting, channel 8), which had already been established, followed followed the NHK station between 1956 and 1958. Over channel 4, New Osaka Television Broadcasting (NOTV) of Osaka Yomiuri Newspaper (renamed to Yomiuri Television Broadcasting (YTV) just before the opening of the station), Kinki Educational Culture Television and Kansai Educational Culture Broadcasting competed and the situation deteriorated. When it got stiff, NOTV suggested bringing channel 2, which had been assigned to NHK in Himeji, Hyogo Prefecture, to the Osaka area. As a result of this, channel 2 was assigned to NHK Osaka (analog General Television), and in the Osaka area, 2 frequencies, channel 4 and channel 10 were licensed as a quasi-educational station.

However, regarding the treatment of the two educational bureaus, Kakuei Tanaka, then Minister of Posts and Telecommunications, suggested that MBS and NOTV merge, respectively, but NOTV firmly refused. Next, the two education companies merged and merged with either MBS or NOTV) (Kanto wide area including Tokyo area ), instead of abandoning the same channel 4, chose the path of independent opening. This caused the channel numbers of the NTV and NET series to be reversed on a series basis in the Tokyo and Osaka areas until the network affair was resolved. After that, the TBS affiliate also had different channel numbers (TBS is 6 and MBS is 4), and only the Fuji TV system had the same channel number in the Tokyo and Osaka areas.

The reason why MBS chose channel 4 was that many TV receivers at that time had only 6-channel tuners, and channel 10, which was the end number, was said to be disadvantageous in terms of sales policy, and that NHK TV had not used it before.

Since its opening, MBS has emphasized 4 by introducing the "4 mark". In the April 1975 reorganization when the network affair was dissolved, The Drifters used the catchphrase "Channel 4 from April!". In this way, "Channel 4" was established, and the remote control key ID for digital TV broadcasting became "4" (all other Osaka wide area stations also used the same remote control key ID as analog).

In addition to the remote control key ID "4", RKB Mainichi Broadcasting in Fukuoka Prefecture uses "4" for the same reason.

In principle, the remote control key ID "4" is used by many Nippon Television affiliates , but the remote control key ID for Yomiuri TV broadcasting of the same Osaka wide area station and Nippon Television affiliated quasi-key station is the parent of the analog broadcasting channel. The same "10" as the analog station is used.
