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".

JOOR-TV

• Mt. Ikoma: Channel 4

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.
