A year split into four
Japanese TV anime is scheduled in four blocks of three months each. New shows start together in January, April, July and October, and fans call these the winter, spring, summer and autumn seasons. A three-month block is called a cour, a broadcasting industry term that has become everyday vocabulary among viewers. In the month a season turns over, a wave of new titles arrives at once, while the previous season's shows reach their finales at roughly the same time. That is why anime fans plan their viewing around the question of what to watch this season.
One cour, two cours and split runs
How many cours a show gets changes the viewing experience. A one-cour show has to finish a chunk of story within a single season, so it moves quickly, while a show with two consecutive cours has room to build its characters and world slowly. Split runs are also common: two cours are made, but the series takes a season or more off between the halves. The break buys the production time to keep to schedule.
- One cour: 12 to 13 episodes, a complete story or a single arc
- Two consecutive cours: 24 to 26 episodes over six months without a break
- Split two cours: a gap of a season or more between the halves
- Long continuous run: a weekly series that ignores season boundaries
Why shows stop at around twelve episodes
Many late-night TV anime are financed by a production committee, in which several companies pool the budget. Publishers, music labels, broadcasters and merchandise makers invest together and share the risk, so it is easier to make one cour, see how it is received and decide on more later than to commit to a long run up front. As a result, a first season often ends at a natural break in the source, and whether a sequel follows depends on its performance and how much source material remains. This structure is also why finales can feel as if they stop mid-story.
Reading seasons from their titles
There is no consistent naming rule for anime seasons, which regularly confuses newcomers. A subtitle may replace the number, the source's arc name may be used as is, and a season labelled 'final' may itself be split into several parts. Knowing the labels below makes it easier to work out what is what in a listing. When a label is ambiguous, checking the air year and season alongside it almost always settles the order.
- 'Season 2' or a plain sequel number: the most common label for the next season
- 'Part 2' or 'second cour': the back half of a split run, not a separate season
- An arc name: a season titled after a story arc in the source
- 'Final season': may be divided again into several parts or films
Why the gaps between seasons are long
If the source manga is still being serialised, the anime has to wait until enough chapters accumulate so it does not overtake the original. The schedules of the director, key animators and studio also have to line up, so it is not unusual for the next season to arrive years later. Conversely, continuous long runners sometimes insert anime-original episodes that are not in the source to widen the gap. A long wait does not mean production has been cancelled, so rely on official announcements for news of the next season.
Common disruptions during a run
Even within one season, schedules do not always go to plan. Shows on a tight production schedule may insert a special episode or skip a week, and the last few episodes can slip into the following month. Animation that fell short on broadcast is sometimes touched up for home video or reruns. These changes are usually adjustments to protect quality, so there is little reason to worry too much.
- Special or recap episodes: summarise earlier events in place of a new episode
- Off weeks: a week skipped for sports coverage or special programming
- Delays: the premiere or the final episodes are pushed back
- Corrected animation: fixed versions appear in reruns or on home video
Planning your viewing season by season
Dozens of shows start at once each season, so following them all is unrealistic. A practical approach is to pick a generous list of candidates at the start, watch the first two or three episodes of each, and cut down to a handful to keep. Following weekly lets you talk about episodes with other viewers, while binge-watching after the finale keeps you immersed without interruption. For split runs, rewatching the last few episodes of the first half before the second half starts keeps the thread intact.
- Start of season: choose plenty of candidates and watch only two or three episodes
- Mid-season: trim the list and organise it by weekday
- End of season: save the rest for a binge once they finish
- Split runs: rewatch the end of the first half before the second begins
Watching from outside Japan
More and more shows now appear on international streaming services almost immediately after their Japanese broadcast. Rights are licensed country by country, however, so the same show can be on a different service, at a different time, depending on where you are. Late-night shows air after midnight Japanese time and are sometimes listed under the following day, so go by the schedule your own service publishes. Some services carry only the first season of a series, so checking that every season is available before you start avoids being cut off halfway.
