Kaoru Touno's family is falling apart. After the death of a sibling and his parents' divorce, he no longer feels any peace at home. Following a heated confrontation with his father, Kaoru runs out of his house and finds himself before a mysterious tunnel, which pulls him in. Bewildered by what he sees inside, he rushes to the exit, picking up a bird that looks identical to his deceased pet on his way out.

Upon emerging outside, Kaoru realizes that, despite him spending just a few minutes inside the tunnel, an entire week has passed. The bizarre experience leads him to remember the rumors of "Urashima Tunnel"—a passage that grants wishes in exchange for one's lifespan. Given the resurrection of his pet bird, Kaoru cannot help but wonder if another visit can help fix his messed up life.

However, when he returns to the entrance of the mysterious tunnel, Kaoru realizes that he has been followed by Anzu Hanashiro, a new transfer student in his class. She also knows about the rumors and asks him to help her with an experiment—it turns out that she, too, has a wish that only the tunnel can grant.

Tunnel to Summer is a movie anime that has so much sentimental value, with great key messages hidden under minimal storytelling (but captivating) waiting to be discovered!

In my opinion, Tunnel to Summer is undeniably will be one of interesting best 2023 anime candidates to being considered.

Based on my experience, watching Tunnel to Summer without knowing any storyline & its trailer would provide an exceptionally captivating experience and this will grows on you If have chances of finish reading its original Light Novel & Manga

Because the main storyline and key messages of both novel and anime is almost the same. The differences are in details + ...

Great animation and voice acting. I'd highly recommend watching if these two are your main priorities as Studio CLAP did an amazing job of illustrating beautiful sceneries of rural Japan and precisely capturing the character's emotions. No lazy/rushed drawings. The music's pretty lit too, but nothing out of the ordinary.

What was really a shame was the pacing of the film - incredibly abrupt (short movie-time problems…) and a lot of the scenes felt really off because of it. I haven’t read the original novel, but you can tell a lot of small but important details have been cut off. As a result, some ...

I'll keep it short. I read the light novel and honestly this was a REALLY disappointing adaptation. Scenes were changed, entire CHARACTERS were basically cut out and had no screentime, and even the entire MAIN THEME OF THE BOOK WAS COMPLETELY GONE! Please I beg of you just read the light novel and not this movie, it really doesn't do the source material justice... The only plus is the art and animation and even that doesn't matter because what ISN'T eye candy nowadays. I also didn't like the voice acting, everyone sounded like a robot and spoke quicker ...
