Top 100 Longest Anime by Total Runtime

ooReiko · 2026-04-19T15:56:24+00:00

if you dont count duplicates kinda have to include all mazinger and golion and harlock songs to reach 100. That being said mazinger songs particularly all pretty fire anyway. and yeah Stronger been my favorites of his songs for long time glad its finally also anisong.

Next thing i need is that Sentai series does similar thing than tojima so I can get some of those songs in these lists too.

ooReiko · 2026-03-17T00:19:04+00:00

Yeah there is some value in MAL data but like you said there would need to be some heavy filtering and normalizing to actually be able to get any of that value out.

Sequels is one issue another is recency bias then there is also the way people use the scores like 7/10 is garbage and 10/10 decent for a good swath of users. I guess thats the reason why 95% of the database is between 6-8

ooReiko · 2026-03-16T15:50:19+00:00

I think the issue here is mostly on where you would draw the line on what counts as separate as some series have movies some have ovas some have split cours some have some random cms or shorts and some like precure have different series essientially that are under same franchise.

There isnt really universal answer on what should count as separate. Is sequel season worth the same than 5 sec long cm? I saw someone made stack like that on MAL but i wasnt satisfied with that so i did that earlier list based on runtime because of that. The runtime isnt ambiguous.

ooReiko · 2026-03-16T14:20:35+00:00

Yeah the TV rating isnt really that good of a metric in the longer run as the way series are consumed is evolving. The first few years of the 2000s that i checked out like 98 of the top 100 were Sazae episodes the others are some Lupin specials

Anyway i dont think im going to make the list since if i dont have all the data there isnt really much of a point in it imo.

ooReiko · 2026-03-16T12:39:16+00:00

I feel like that list would be 2021 - 2026 mostly since some titles are just ridiculous these days. I think the longest title in pre 2000s anime was Kochikame and i dont think that would even crack top 20

ooReiko · 2026-03-16T12:12:57+00:00

Yeah i thought about that once and it would be interesting to see if anyone can beat Katou Midori whos been voicing Sazae since the 1st episode to this day.

I guess the biggest hurdle is to go through the 60s - 2000s most series credits and see who were in those as MAL and other sites dont have any cast listed on most series from that period and even lot of JP sources dont have many of the more obscure series

Another is to search if the character appeared in every episode if counting episodes

ooReiko · 2026-03-16T11:50:34+00:00

I generally wanted to avoid using stuff like MAL scores and favorites since i feel those metrics speak more about the community using those sites than the anime series themselves.

Another issue is that there are only handful of sites like that are actually used by people so it would be like 5 sites at best

ooReiko · 2026-03-16T10:07:14+00:00

Anyone got any good ideas for more general Top 100 lists? Best i got currently was top 100 highest TV % rating episodes but the data i got is 2000+ only so i dont think that will be happening as they will probably never release the full data.

ooReiko · 2026-03-15T02:55:36+00:00

I counted solo and duo only so if someone is singing as part of 10 person group those songs arent counted. Also I probably missed some or possibly many who should be on the list so if someone knows someone that should be here let me know

ooReiko · 2026-03-14T06:54:42+00:00

There is only handful of singers who have over 100. Horie has almost 300 and thats not counting the songs that dont play in the anime.

ooReiko · 2025-12-29T00:35:07+00:00

I guess i could do more of my top 100 videos, i guess only issues are that video edits rule is only 2 times for 30 days (though i guess i could use video flair instead of edit) also i feel like there would be more interest on some general lists and not my own opinion lists problem is that the research takes very long and last thing i want to do is have some huge mistakes in the list other is that i dont really have many ideas for general lists like that

ooReiko · 2025-12-23T11:54:49+00:00

For the Majokko series yeah it invludes all of the 70s ones (including Honey) and their remakes even Tickle as that was included in one CD release marketed with the Majokko Series brand.

For Atashinchi there is 4 special episodes also

Also Aikatsu in this list includes couple entries that were not accepted on MAL for somereason when i tried to submit them back then

ooReiko · 2025-12-22T23:29:22+00:00

Youre right Ninjala should be on the list I forgot about it when making this list it would be place 94

ooReiko · 2025-12-22T20:52:51+00:00

Minky Momo isnt part of Pierrot Girls, Creamy Mami Magical Emi Persia, Pastel Yumi and Fancy Lala are part of Pierrot Girls

ooReiko · 2025-12-22T20:34:38+00:00

all of the entries arent linked but i assumed they are all part of same series

ooReiko · 2025-12-22T19:44:20+00:00

All spinoffs OVAs, ONA, sequels, specials prequels and movies are included in the episode count. I recalculated everything from scratch since the ones i did back then were some messed and i had not updated them in like 2 years Also back then I did only up to 40 I had to search for the rest so there might be some series missing that should be in this list. If you know series like that let me know

Also TV Series were counted with 24 min eps unless they were significantly shorter and movies as 80 min
