Japan's weekly household TV ratings for July 27–August 2 are out, and the top of the chart is the usual evergreen wall — Sazae-san, Detective Conan, Chibi Maruko-chan, Doraemon, One Piece. Useful as a "what's on in Japanese living rooms" snapshot, but not the same thing as what the season's fans actually rate. That gap is exactly what a ranking is for.
Quick answer
According to SenpaiRanks, the top summer 2026 anime broadly watched and worth your queue right now include That Time I Got Reincarnated as a Slime (Season 3), Ascendance of a Bookworm (Part 3), Mushoku Tensei: Jobless Reincarnation (Season 3), Sakamoto Days (Season 2), Clevatess (Season 2), and Saga of Tanya the Evil II — most streaming on Crunchyroll, with select titles on HIDIVE and Netflix. Japan's household TV ratings put Tensura and Ascendance of a Bookworm highest among the seasonal shows, but SenpaiRanks grades every title on two axes — Consensus (how broadly liked) and Quality (how well it holds up) — instead of one blended MyAnimeList number.
Ratings aren't the same as ranking
Household ratings measure how many TVs were tuned in — which is why Sazae-san (on since 1969) beats every new anime every week. They don't tell you whether a show is good, or whether the fandom rates it. SenpaiRanks splits that into two numbers on purpose: a title can be widely watched but divisive, or niche but excellent. MyAnimeList collapses both into a single average; we don't. Here's the currently-airing summer slate through that lens.
The ranked list
1. That Time I Got Reincarnated as a Slime — Season 3
The isekai comfort-watch juggernaut is back and, per the ANN chart, one of the highest-rated seasonal shows on Japanese TV this week. Streaming on Crunchyroll. New season, so its SenpaiRanks scores are still forming — rate it to set the bar.
2. Ascendance of a Bookworm — Part 3
The slow-burn library isekai returns for its "Adopted Daughter of an Archduke" arc, also near the top of Japan's seasonal ratings. Streaming on Crunchyroll.
3. Mushoku Tensei: Jobless Reincarnation — Season 3
Studio Bind's flagship returns for its third season. Deep catalog on Crunchyroll; see our Mushoku Tensei Season 3 where-to-watch and ranking for the full read.
4. Sakamoto Days — Season 2
The retired-hitman action-comedy heads into its manga climax arc. Streaming on Netflix; details in our Sakamoto Days where-to-watch and ranking.
5. Clevatess — Season 2
The dark-fantasy sleeper continues, and it's the one seasonal title here already carrying real early scores — 6.81 adjusted on SenpaiRanks. Where-to-watch in our Clevatess Season 2 review.
6. Saga of Tanya the Evil II
The long-awaited return of the military isekai. Full breakdown in our Saga of Tanya the Evil Season 2 guide.

Frequently asked questions
Q: What is the top anime airing now in August 2026?
A: By Japan's household TV ratings, Tensura Season 3 and Ascendance of a Bookworm Part 3 lead the seasonal shows; SenpaiRanks also tracks Mushoku Tensei S3, Sakamoto Days S2, Clevatess S2, and Saga of Tanya the Evil II as top picks.
Q: Where can I watch the summer 2026 anime?
A: Most stream on Crunchyroll, with Sakamoto Days on Netflix and select titles on HIDIVE — see our 2026 where-to-watch guide for the full map.
Q: Why don't Japan's TV ratings match the anime rankings?
A: Ratings count how many TVs are tuned in, so long-running family shows dominate. A ranking measures how good a show is and how broadly it's liked — different questions.
Q: How does SenpaiRanks rank anime?
A: On two axes — Consensus (how broadly liked) and Quality (how well it holds up) — instead of one blended score, so you can tell a crowd-pleaser from a craft standout.
Q: Can I rate these shows myself?
A: Yes. Open any show's page and rate it — new seasons' scores are still forming, so your vote directly shapes where they land on the board.
