This guide totals the episode count and watch time across every TV season plus both films, then suggests practical viewing plans whether you want a weekend binge or an easy daily pace.
What you’ll learn

- Total watch time including both theatrical films
- Per-season runtimes (so you can plan sessions)
- Binge vs. relaxed viewing plans that fit your schedule
- A simple, efficient watch guide for first-timers
The Bottom Line — Total Episodes & Watch Time (Anime + Movies)
If you watch all TV episodes plus the two movies, you’ll need about 30 hours in total.
As of 2025, the TV anime spans 5 seasons with 63 episodes.
Total episode count
The TV anime is divided into five arcs/seasons:
- Season 1: Tanjiro Kamado, Unwavering Resolve Arc — 26 episodes
- Mugen Train Arc (TV version) — 7 episodes
- Entertainment District Arc — 11 episodes
- Swordsmith Village Arc — 11 episodes
- Hashira Training Arc — 8 episodes
TV total: 63 episodes
Plus two movies:
- Mugen Train (The Movie): 117 minutes
- Infinity Castle — Part 1 (Theatrical): 155 minutes
So your complete target is 63 episodes + 2 films.
Watch-time estimate
Assuming ~24 minutes per TV episode:
63 × 24 = 1,512 minutes (~25.2 hours)
Movies combined: 117 + 155 = 272 minutes (~4.5 hours)
Grand total: 1,512 + 272 = 1,784 minutes ≈ 29.7 hours
Round figure: about 30 hours—perfect for a focused weekend binge or a few weeks of relaxed viewing.
Season-by-Season Episode Counts & Runtimes
Season 1 — “Unwavering Resolve Arc”
The origin of Tanjiro’s journey through the Natagumo Mountain climax.
- 26 episodes → 26 × 24 ≈ 624 minutes (~10h 24m)
A crucial foundation that pulls most viewers straight into the world.
“Mugen Train Arc” (TV version)
Originally a feature film, later broadcast as 7 re-edited episodes.
- 7 episodes → ~168 minutes (~2h 48m)
Includes extra scenes for Rengoku’s mission that aren’t in the film cut.
“Entertainment District Arc”
Uzui Tengen leads a spectacular battle in Yoshiwara.
- 11 episodes → ~264 minutes (~4h 24m)
The finale runs longer than a standard episode, so real-world time may be slightly higher.
“Swordsmith Village Arc”
Tanjiro teams up with Muichiro Tokito and Mitsuri Kanroji.
- 11 episodes → ~264 minutes (~4h 24m)
“Hashira Training Arc”
A compact bridge to the final saga, focused on growth and relationships.
- 8 episodes → ~192 minutes (~3h 12m)
Viewing Plans & Smart Tips
Weekend “Binge” Plan (for busy people)
If you can block out time, try a three-day sprint:
- Day 1: Season 1 (~10h) + Mugen Train (TV cut) (~3h)
- Day 2: Entertainment District (~4.5h) + Swordsmith Village (~4.5h)
- Day 3: Hashira Training (~3h) + Both movies (~4.5h)
That’s ~10 hours per day across three days. Schedule meals and short breaks to stay fresh.
Relaxed “Take-Your-Time” Plan
Prefer to savor it?
- Weekdays: 1 episode per day (~30 minutes with intros/outros)
- Weekends: 2–3 episodes together (1–1.5 hours)
You’ll comfortably finish in 4–8 weeks including the films.
Notes & caveats
- Streaming bundles can differ by platform; confirm the correct order.
- Some episodes are specials/extended, so runtimes may exceed 24 minutes.
- Mugen Train (movie) and Mugen Train (TV) overlap heavily; watching either one is fine for the story (the TV cut has added scenes).
- Spin-offs (e.g., Kimetsu Academy) are fun extras and not required for the main plot.
- Following the intended order keeps the narrative smooth and the emotions strongest.
