Affiliates that initially planned to join but later withdrew

Broadcasting area(s)		Station			Ch.	Current affiliation	Current NNN/NNS affiliate	Note(s)
Prefecture	Region	On air branding	Abbr.	Call sign
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.[17] However, in response to some news programs, materials were also sent out and paid for the net share.[18]
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.[19]
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).[20] Even after the establishment of NNN/NNS, the official membership as a dual FNN/NNN affiliate was not achieved.
