Demon Slayer has become one of the most impactful anime series of the last decade. Its initial success as an anime series has been clear to see from day one, but what has truly allowed the series to stand out in unique ways and revolutionize the medium as a whole is its theatrical movie release.
The success streak of Demon Slayer started with the Mugen Train, and it’s now being carried forward by the new Infinity Castle Saga. Demon Slayer: Infinity Castle Part 1 was released back in July 2025, and its success surpassed all expectations. Now we await Demon Slayer’s return with the next movie project, currently referred to as Infinity Castle Part 2. In the meantime, however, a new Demon Slayer release is ongoing in Japan, giving fans free content from Koyoharu Gotouge’s story to enjoy and get ready for the release of Infinity Castle Part 2. All four seasons of Demon Slayer are available to watch in the form of a rerun to usher in the release of Demon Slayer: Infinity Castle Part 2.
Demon Slayer Rebroadcasts All TV Anime Episodes In Japan
Demon Slayer has become a household name known all around the world when it comes to anime. Of course, it’s greatly popular in North America, like the U.S., but in its home country, Japan, it’s a massive phenomenon as well. Japanese fans have fallen completely in love with the Demon Slayer series, and that is clearly reflected in the performance of its theatrical releases, as well as manga sales over the years.
The demand for Demon Slayer is undying, and that is especially the case after its most recent blockbuster hit, titled Demon Slayer: Infinity Castle Part 1, which first saw its premiere in Japan in July 2025. Because of the movie’s popularity, it became the Number 1 highest-grossing Japanese movie of all time, and the Demon Slayer franchise as a whole has been impacted positively.
Additionally, because of the high stakes set up by Demon Slayer: Infinity Castle Part 1, fans in Japan and all around the world have been eagerly awaiting the sequel, which will continue the raid on the Infinity Castle and see the defeat of more of Muzan’s powerful underlings. For now, this sequel movie has no title, but it’s generally referred to as Demon Slayer: Infinity Castle Part 2.
To keep fans just as excited as they were when they watched Infinity Castle Part 1, Japan has employed a very interesting tactic to keep the hype alive. The huge Japanese broadcast channel Fuji, and its affiliated networks, have decided to completely rerun the Demon Slayer series. This process already started back on April 5, 2026, with the first episode of Demon Slayer having aired.
Now, a few months in, Japan has reached the Mugen Train arc, with episode 4 of the second season debuting on November 8, 2026. At the current rate of the anime, we can expect this series to keep going until next year, specifically June 13, 2027. This is, of course, assuming the series takes no breaks and keeps broadcasting consistently week by week, as usual, on Sunday at 9:30 AM Japan Standard Time.
All Episodes Covered In The Demon Slayer Rebroadcast And What It Means For Infinity Castle Part 2
The currently ongoing Demon Slayer rebroadcast is definitely interesting for the fans of the series. It is very uncommon for a full series to be rebroadcast, which goes to show Kimetsu no Yaiba’s great impact on Japan and its unwavering popularity. For fans who are curious and would like to rewatch the series side by side with Japan from the comfort of their own home, using various streaming platforms like Crunchyroll is a good idea to enjoy all four seasons of Demon Slayer in one go.
For context, Demon Slayer features 63 episodes in total. Season 1 of the series covers the Final Selection Arc, the First Mission Arc, the Asakusa Arc, the Tsuzumi Mansion Arc, the Mount Natagumo Arc, and the Rehabilitation Training Arc. In total, it has 26 episodes. Then, there’s Season 2, which is currently airing in Japan.
This season covers the Mugen Train Arc and the Entertainment District Arc. In total, there are 18 episodes to catch up on, and this could be considered the most popular TV installment of the series. For Season 3, there’s the Swordsmith Village Arc, made up of only 11 episodes in total. There’s also the final season of the series, Season 4, made up of the Hashira Training Arc, which is the shortest of the series, with only 8 episodes in total. By taking on a rewatch, fans will be up to date with all information regarding the series, which will allow them to go into Infinity Castle Part 2 with a refreshed memory and updated knowledge that might’ve needed brushing up after a while.
Demon Slayer Rebroadcasts Pave The Way For Infinity Castle Part 2
The Demon Slayer rebroadcast in Japan is interesting for more than one reason. While it shows how popular Demon Slayer is, it is also a clue concerning the release date of the next Demon Slayer movie, the highly anticipated Infinity Castle Part 2. That is because, logically, it makes no sense for Japan’s major broadcasting channels to kickstart a rebroadcast of Demon Slayer that they cannot finish in time. As previously mentioned, the broadcast started on April 5, 2026, and is set to end on June 13, 2027, airing 63 episodes in total. This means that Demon Slayer: Infinity Castle Part 2 isn’t releasing before mid-June. Likely, the release date of the next movie will coincide very closely with the end of the TV broadcast.
With these assumptions made, we can logically conclude that Demon Slayer: Infinity Castle Part 2 is releasing sometime in Summer 2027 for Japan, which is also the peak season for big blockbuster hits to be positioned. It’s also likely that Ufotable Studio is trying to release the movie in July 2027 to coincide with the 2nd anniversary of Part 1, but recent confirmed reports also suggest that the movie’s release could be set a couple of months later in September 2027, specifically on September 17, 2027, under the licensing of Sony.
For now, we can only make assumptions about the release date of Demon Slayer: Infinity Castle Part 2. However, one event that might shed more light on the matter is the upcoming Jump Festa 2027. Demon Slayer has already been confirmed as a major participant for their event, taking center stage as part of the Super Stage Red on December 19, 2026. New movie information is sure to be unveiled here, which could include a concrete release date as well.
Demon Slayer has four TV anime seasons out, as well as three movies. All TV seasons and movies are available to stream on Crunchyroll.
