🇯🇵Top 10 Anime Loved by Japanese in Their 20s (based on a 2025 reader survey)

ByYumi November 27, 2025December 2, 2025

To make this list grounded, I’m using AnimeAnime.jp’s 2025 “Life Best Anime” reader results, specifically the 20s reader section. Note: this reflects that site’s readership (not a perfect “all Japan” census), and some ranks include ties.

#1 (Most supported by 20s readers)

Gintama — sci-fi Edo comedy that hits you with absurd humor… then suddenly wrecks you emotionally.

“Best #2 tier” (multiple titles tied in the survey)

CLANNAD — a slow-burn, heart-squeeze story about connection, family, and growing up. (Bring tissues.)
Assassination Classroom — a classroom comedy-thriller where students must kill their teacher… who might be the best teacher they’ll ever have.
Haikyuu!! — pure motivation fuel: teamwork, rivalry, growth, and that “one more point” adrenaline.
Fullmetal Alchemist: Brotherhood — big themes (loss, sacrifice, ethics) with world-building you can sink into for days.
My Hero Academia — classic “becoming who you want to be,” with a huge cast and nonstop hype moments.

Other 20s fan-favorite titles mentioned in the same 20s section

Re:Zero − Starting Life in Another World — time-loop survival meets emotional pain: “retry” doesn’t mean “easy.”
Bungo Stray Dogs — supernatural detectives + stylish battles + characters you love and fear at the same time.
Detective Conan (Case Closed) — comfort-mystery marathon: clever cases, long-running lore, and never-ending “just one more.”
Shangri-La Frontier — gamer fantasy done right: skill, strategy, hype boss fights, and “I want to try that game.”
