WOWOW was a satellite channel, and was thus responsible for 80% of “I’m really surprised this didn’t air later at night” thoughts I had while gathering timeslot information. This summary also took less time to put together because most of their dedicated anime blocks were a pretty localized phenomenon, opening between 1998-1999 and ending, at the latest, in 2003.
General boilerplate stuff:
If you’re curious about the details, you can find the data I’ve gathered on this spreadsheet. Note on the format: the master list has just the networks, timeslots, and years of airing. Other sheets contain the shows aired in a given year and those aired on non-Japanese TV, with relevant links for the numerous series for which the Japanese wikipedia page didn’t provide sufficient information on the timeslot.
For each broadcaster, I’ll be asking two questions. First, which, if any slots did they have dedicated to anime in general? To qualify as an anime slot for the purposes of this exercise, a timeslot has to have aired premieres of at least 3 TV anime from 1994 to 2000. This excludes, for example, the Fuji TV Sunday 18:30 slot, which has been running Sazae-san for a really long time. I’m more interested in timeslots that would have been available to new shows during this period. I do track timeslots before and after the period to get an idea of where their demos originated and where they ended up.
Second, which, if any shows did that broadcaster air after midnight? I want to give as complete a view as possible on the stance different companies took in regards to airing anime late at night. Since I’ve been poring over the data, I already have a decent idea of what the answer is going to be, but it’s neat to look at how different broadcasters’ stances were during this period.

-Much of the anime listed above (the shows in the Monday/Tuesday 19:00 slots) aired in the Anime Complex family of blocks. Anime Complex NIGHT, the third and final installment, started in 2001 and lasted two years, ran the sequel to Steel Angel Kurumi as well as Hanaukyo Maid-tai and Rizelmine.
-Whatever Shine Magic was bumped off multiple anime blocks, forcing Kazemakase Tsukikage Ran and Oh! Super Milk Chan into new slots for their final month.
-Only 3 shows actually aired after midnight on this channel, but they aired some pretty mature stuff (in many different meanings of the word) during their “prime-time” evening hours. This is possibly somewhat analogous, though certainly not identical, to how the move to cable TV allowed anime to get away with more minimal editing in the US.
-No current anime timeslots started in this period on WOWOW have lasted through to the modern day. The last anime they aired as primary programming were Ozma in 2012 and Mamoru-kun ni Megami no Shukufuku wo/Kaiba in 2008.
-The original FMP anime was slated for Fall 2001, before being delayed due to the recent occurance of the 9/11 attacks. Probably a sensible move for the network, though it represents a talking point for those wary of the can of worms self-censorship can open.
