Japan’s Biggest Review Site Reveals Most Popular Anime of 2025 has ignited discussion across fandoms worldwide. If you’ve ever wondered which series are dominating hearts and charts in Japan this year, you’re in the right place. In this deep dive, we’ll break down the definitive list from Filmarks—the nation’s leading film and anime review platform—exploring why these anime resonate so strongly, how they compare, and where you can stream them right now.

According to Filmarks’ mid‑year report, the anime scene in 2025 is more dynamic than ever. A blend of established franchises and breakout hits have claimed the top spots. What’s remarkable is the mix of genres—from action‑packed epics to heartwarming slice‑of‑life tales—demonstrating the diverse tastes of Japanese viewers.

• Demon Slayer: Hashira Training Arc – Continuation of the record‑shattering Demon Slayer saga.
• Frieren: Beyond Journey’s End – A contemplative, character‑driven fantasy that redefines post‑heroism.
• Undead Unluck – A fresh take on supernatural shonen, gaining traction for its irreverent humor.
• Cute Executive Officer II – Comedy anime proving that lighthearted series can still top charts.
• PLUTO – Tezuka-inspired sci‑fi that bridges nostalgia with cutting‑edge animation.

Each title boasts a unique appeal—whether it’s the emotional weight of Frieren or the breathtaking action sequences of Demon Slayer.

This table offers at‑a‑glance context for ratings and streaming options, helping you decide what to watch next without endless searching.

Deep Dive: What Makes These Anime Stand Out?

Demon Slayer: Hashira Training Arc continues Ufotable’s tradition of blending hand‑drawn artistry with fluid CGI, delivering fight scenes that feel almost cinematic. Fans praise the emotional stakes as Tanjiro and friends push beyond their limits—an element that consistently trends on social media.

By contrast, Frieren: Beyond Journey’s End slows the pace, focusing on the aftermath of victory. Its meditation on memory, loss, and the meaning of heroism elevates it above typical fantasy fare. Viewers often describe it as a “healing” anime, making it an ideal recommendation for anyone seeking depth.

Undead Unluck pairs a morally ambiguous protagonist with fast‑paced action and witty banter. Its willingness to subvert tropes has sparked lively discussions on Reddit and Discord communities—proof that a series doesn’t need decades‑old source material to capture imaginations.

Where to Watch Your Favorite Anime

Finding the right streaming service can be tricky. Here’s a quick guide:

• Crunchyroll: Exclusive rights to Frieren and Undead Unluck.
• Netflix: Home to Demon Slayer movies and select episodes of the Arc.
• HIDIVE: Catch Cute Executive Officer II and a curated library of comedies.
• Amazon Prime Video: Hosts PLUTO with optional Japanese audio and subtitles.

Leveraging free trials or bundled subscriptions can help you binge responsibly without breaking the bank.
