Best Anime Debuts of Winter 2025

In life, you only get one chance to make a first impression, and that saying holds true for the anime industry, especially in an era as active as this. The Japanese animation industry pumps out so many new shows a season, so many new episodes weekly, that these days, it can feel difficult to sift through all the throwaway nonsense to find the shows that are really worth watching each new anime season.

That’s where today’s list comes in! With the Winter 2025 anime season recently kicking off, we’ve gone through the many, many anime debuts on offer, and picked out the best new anime on the scene this season. We’ve made sure to only include new anime for this list – so while Dr. Stone, The Apothecary Diaries, and Solo Leveling are all delivering great episodes week after week, you won’t find them on this list. This one is for the industry underdogs! So, get your calendars ready, and let’s get into our list of the best anime debuts of Winter 2025!

Flower and Asura

One of the many common misconceptions about anime is that every show is an action-packed battle shonen, and while this misconception can be owed to the fact that many of those shonen find instant success in the industry, it’s shows like Flower and Asura that keep the industry on its feet through grounded, realistic storytelling. Based on the manga of the same name, Flower and Asura tells the story of a shy young girl who dreams of joining a broadcasting club, but can’t because she has to get a ferry home, and the ferry leaves at 5pm every day. I’m not sure I’ve fully sold you on the premise with that description, but I promise it’s more interesting than it sounds.

From the first episode alone, I can tell this is going to be one of those ‘chase your dreams’ anime – think Naruto trying to become Hokage, but with much lower stakes. The animation here is very nice, particularly shining through at the end of the first episode, and the soundtrack is pleasant enough to make you feel drawn into this incredibly vague island-school that the protagonist is attending. Though the show is not quite as gripping as it yet, in many ways the storytelling reminds me of Your Lie in April, one of my favourite anime series of all time. So, if Flower and Asura can even come close to reaching those heights, it’ll be a worthwhile watch. There’s real potential for this show to be a hidden gem down the line – if it looks like your thing, get on board the train (ferry?) as soon as possible.

Flower and Asura streams Tuesdays, weekly on HiDive.

Tasokare Hotel

I love a good mystery anime. I also love an anime that plays with the idea of death as a concept. Tasokare Hotel takes those two things and blends them together into one neat, little, slightly creepy package. Tasokare Hotel is based on a mobile game of the same name, a charmingly unique source material for an anime when contrasted with all of the manga adaptations we get season after season. The premise is simple – a girl is stabbed, ends up in a hotel that exists between life and death, and must figure out the truth of her identity before she can leave, either returning back to life, or passing on to the afterlife.

In many ways, Tasokare Hotel feels like a callback to Death Parade, a show that was, albeit, a lot more intense than this one, but played with the idea of a space between life and death in the same way. As fun as Tasokare Hotel currently feels, I can see there being some real, emotional pay-off when all is said and done. There’s nothing completely groundbreaking here, and I spotted re-used animation frames in the premiere episode a few more times than I’d like to admit, but nothing that truly hinders the fun mystery vibe the show has going for it in its early stages. Check this one out if it sounds like a show for you!

Tasokare Hotel airs weekly on Wednesdays, and can be streamed right now on Prime Video.

Sakamoto Days

Easily the most anticipated debut anime of Winter 2025, the premiere episode of Sakamoto Days had a lot of hype to live up to. I’m completely unfamiliar with the source material, so I have to say that going into this blind, I didn’t know what to expect. I was pleasantly surprised by the great blend of dark comedy and action on display here, combined with the heartwarming premise of a former gangster turned homely store clerk. Particularly for fans of shonen anime, this is the debut show to watch this season, and likely the only series that will contend with the heavy-hitting sequel seasons of Winter 2025 in the long run.

The animation here is solid, though not as amazing as I was hoping for. The opening in particular is pretty embarrassingly bad, especially considering they got Vaundy to perform the opening song. Sure, some people unfamiliar with the anime industry may disregard the opening as merely flashy filler, but you should never underestimate the wonders a great opening can do for a show in terms of connecting with new viewers. Opening aside though, Sakamoto Days is absolutely one of the stand-out anime of the season, and must-watch television for any anime fan trying to keep up with the biggest current shows.

You can catch new episodes of Sakamoto Days, streaming Saturdays on Netflix.

Zenshu

Zenshu is the first original TV series on our list, as in, there’s no source material that this show is based on. This makes my next point on this especially poignant. There is genuinely a moral dilemma at hand when watching this series. A show about an overworked, unhealthy animator being pushed to the brink by her job – and this is made by MAPPA, a studio that has regularly come under mainstream media fire for its poor working conditions. If that’s not ironic, I don’t know what is.

I’m going to attempt to look at this show from an objective standpoint though, and with that in mind, this is a very enjoyable series from its early stages. Your isekai tropes are all there, and unfortunately, the cast isn’t compelling enough just yet to let me look past those tropes, but I do enjoy the unique twist of an animator using her art skills to change the story of her childhood anime that she’s been transported into. Moral reservations aside, Zenshu is a fun anime with a very promising future.

Zenshu airs weekly on Crunchyroll, streaming on Sundays.

Medalist

This is the first anime I’ve ever watched from Studio ENGI, and I have to say, their animation style is absolutely stunning. Here’s hoping Medalist can bring some new eyes to this studio, because as far as sports anime go, this is one of the more emotionally investing ones I’ve seen in a while. When done correctly, sports anime can be a joy to watch – think Haikyuu and Blue Lock, or more recently even, Blue Box. I care very little about any of the sports represented in these shows, but the storytelling is so compelling, you suddenly find yourself cheering at the screen, rooting for those fictional volleyball players to win the big game.

In its early stages, Medalist tells a much smaller-scale story. A young girl dreams of becoming a figure skater, but her mother is apprehensive. As expected, she eventually finds her way onto the ice, and the journey towards her Olympic gold medal begins. For some shows, all they need to do is tell a nice, pleasant story, and this is where Medalist thrives. The dramatising of sports can be a bit much for me sometimes, but it’s balanced out nicely with the emotional storytelling. The manga this series is based on has been well-received over the years, so I’m excited to see where Medalist goes in future episodes – sports anime fans, this is the Winter 2025 show for you!

You can catch new episodes of Medalist, Sundays on Disney Plus.

From Bureaucrat to Villainess: Dad’s Been Reincarnated!

Of all the shows I watched in preparation for this list, I did not expect this one to make the cut at all. From first impressions, I was sure that this was just another generic, throwaway isekai, and in some ways, it does itself no favours in communicating that impression. I do wonder how self-aware these authors have to be at this point with the whole, ‘I got hit by a car and now I’m in another world’ thing – seriously, how many times has that exact scenario happened? However, with this series, at least they got that stuff out of the way fast, and jumped quickly into the comedy-isekai shenanigans.

From Bureaucrat to Villainess: Dad’s Been Reincarnated! tells the story of a man who gets hit by a car and wakes up as the villain of his daughter’s favourite video game. His experience as a father influences his behaviour in the game, and changes the story for the other characters around him. Also, he’s attending a magic school – that part felt sort of shoehorned in. In many ways, From Bureaucrat to Villainess feels like a mish-mash of all sorts of isekai stories that came before it, but hey – if it ain’t broke, don’t fix it. Ultimately, the series aims to be an enjoyable comedy isekai, and an enjoyable comedy isekai it is. It is one of those shows I’m likely to forget about weekly though, so I see a binge-watch at the end of the season in my future.

From Bureaucrat to Villainess: Dad’s Been Reincarnated! streams weekly, Thursdays on HiDive.

Honey Lemon Soda

If you feel like you’ve heard of Honey Lemon Soda before, it’s likely because a live-action movie adaptation of this popular manga series was released back in 2021. In many ways, it feels surprising that this is the first time Honey Lemon Soda has been adapted as an anime. However, I do have to admit – of all the entries on this list, this is by far the one that is best experienced in the background as you do something else. This isn’t meant to insult the show – it has a cosy vibe to it, and the animation is very nice, but plot-wise, you won’t exactly be on the edge of your seat.

The story follows a bullied girl who meets a nice man who saves her from the bullies by shouting at them once. Now she likes him. I did say the plot wasn’t exactly groundbreaking. The unfortunate protagonist garners some sympathy through the misdeeds of others, but she’s irritatingly pitiful at times. For all my DAN DA DAN fans out there, think of Okarun, but if he wasn’t funny. I know I’m making this show sound miserable, and to be honest, it was the last candidate to make it on this list, but it is a nice time. Sometimes you just need a show to unwind to, something that’s mindless and atmospheric, and Honey Lemon Soda will scratch that itch. It just won’t scratch any other itches you may have beyond mindless cosiness.

Honey Lemon Soda releases on Crunchyroll weekly, on Thursdays.

Ameku M.D.: Doctor Detective

While Sakamoto Days did, somewhat predictably, take the crown for the best debut anime of the Winter 2025 season, Ameku M.D.: Doctor Detective is an easy second-place choice for me, and is by far one of the most underrated anime of the season from the jump. Seriously, why aren’t more people talking about this? From its first episode, Ameku M.D. feels like an anime-version of House, and so far, is easily one of the most interesting debut anime I’ve seen in a while. If you’re a fan of medical drama shows, particularly where diagnosing patients with mysterious ailments is at the center, this one’s for you.

I’ve talked a lot on this list about anime characters this season. While the cast of Ameku M.D. is nothing special, aside from Dr. Takao Ameku herself, they play their role perfectly as side-characters to Ameku’s starring role. There’s also a cliffhanger at the end of episode one that sets the show up for some truly bonkers reveals, and I can’t wait to see what mysteries unravel in the hospital as the episodes carry on. If you’re looking for a true hidden gem this anime season, this is the one I recommend the most. The opening is also performed by Aimer, so major points to the show for that.

Ameku M.D.: Doctor Detective airs weekly on Crunchyroll, streaming on Thursdays.
