## Affiliates that initially planned to join but later withdrew

| Broadcasting area(s) | Broadcasting area(s) | Station | Station | Station | Ch. | Current affiliation | Current NNN/NNS affiliate | Note(s) |
| Prefecture | Region | On air branding | Abbr. | Call sign | Ch. | Current affiliation | Current NNN/NNS affiliate | Note(s) |
| Tottori and Shimane | Chūgoku | TSK | TSK | JOMI-TV | 38 | FNN/FNS | NKT | Since the San'in Chuo Shimpo (Shimane Shimbun at the time of its opening) was deeply involved in the opening of TSK, it had a close relationship with the Yomiuri Shimbun, at first the newspaper hoped to open a station as a Nippon Television affiliate, but it was already Nihonkai Television (at that time (1970 to 1973) exclusively in Tottori prefecture) that was carrying Nippon TV programs, so it was opened as a Fuji TV affiliated full net in consideration of mutual entry with Tottori prefecture in the future (in 1973). |
| Kumamoto | Kyūshū | TV Kumamoto | TKU | JOZH-TV | 34 | FNN/FNS | KKT | Observer affiliate. However, in response to some news programs, materials were also sent out and paid for the net share. |
| Kagoshima | Kyūshū | Kagoshima Broadcasting | KKB | JOTI-TV | 34 | ANN | KYT | As a result of the unification adjustment and discussion by three flagship stations in Tokyo (Nippon Television, Fuji Television, and TV Asahi), instead of making the third commercial broadcasting station in Kumamoto Prefecture affiliated to Nippon Television (Kumamoto Kenmin Television), the third station in Kagoshima Prefecture became affiliated with TV Asahi. |
| Okinawa | Kyūshū | Okinawa Television | OTV | JOOF-TV | 8 | FNN/FNS | N/A | Since Okinawa was under the rule of the United States at the time of the preparatory stage for the opening of the station, NTV presented a condition that it would allow the purchase of the program but not cooperate with capital participation (before the launch of NNN). Even after the establishment of NNN/NNS, the official membership as a dual FNN/NNN affiliate was not achieved. |
