[Summer Anisongs] Iconic and Popular Anime Tracks That Feel Like Summer

BRAND NEW WORLDD-51

One Piece OP 6 – BRAND NEW WORLD (720p HD)

This is the opening theme of One Piece, which has been airing since 1999 and could be called the most famous anime in Japan.

All of One Piece’s songs have a refreshing, summery feel, but this one in particular brings to mind the exhilarating speed of ships racing across the sea and intense battle scenes.

The opening theme of Nichijou, a popular gag manga adapted into an anime.

Contrary to the title, it’s a gag anime where seemingly absurd developments unfold that make you think, “Does something like this really happen in everyday life?” This song perfectly weaves that worldview into its lyrics.

Its high-energy, up-tempo progression exudes the zany vibe of a gag anime.

Brimming with a sense of speed, it delivers a refreshing feeling reminiscent of the breeziness of summer.

Katsushika RhapsodyKohei Dojima

KochiKame Two Major Opening Theme Medley

It’s the opening theme song of the anime “Kochira Katsushika-ku Kameari Kōen-mae Hashutsujo.” Unlike the intense main episodes of “KochiKame,” the video leaves a strong impression with its leisurely depictions of scenes from Katsushika.

Even people who have never seen the real Katsushika can feel a certain nostalgia, and through the protagonist Ryō-san, you can savor the atmosphere of a Shōwa-era town.

Muscatyuzu

Yuzu “Muscat” Music Video

Kids love it! The anime Crayon Shin-chan—whose movie version is known for moving even adults—had its 16th opening theme handled by Yuzu.

Muscat is a brisk, refreshing track, complete with handclaps that lift your spirits just by listening.

It’s a staple summer anime song and a go-to dance number for children at events like sports days and school performances.

DAYSFLOW

FLOW 『DAYS』(Music Video Short Ver.)

This song became a hit after being used as the first opening theme for the anime Eureka Seven.

It’s a work by the five-member rock band FLOW, released in 2005 as their 11th single.

Its grand sound, featuring string tones, perfectly matches the image of the anime, with robots flying through the sky.

It delivers both exhilaration and a floating sensation at the same time.

Summer can be nothing but heat, leaving you worn out.

Why not cool off by letting your ears feel the breezy imagery this song carries?

ReunionVaundy

Reunion

This is a number by singer-songwriter Vaundy.

It serves as the opening theme for the TV anime “The Summer Hikaru Died” and is set for release in July 2025.

Vaundy himself delved into the original work and created the song based on a sense of “unease about not knowing what will happen next.” The rock sound, tinged with a foreboding atmosphere, is distinctly Vaundy.

The lyrics reflect the joy of a long-awaited reunion while projecting an unshakable doubt and loneliness—the fear that the other person may no longer be the same.

It meshes seamlessly with the original’s raw, prickling mood and its delicate, complex emotional nuances.

Mekakucity Actors “Kagerou Daze” / Jin ft. Shoichi Taguchi (Sensuous Vector)

This is an insert song from Episode 4 of Mekakucity Actors, an anime adaptation of the world of the song ‘Kagerou Daze’ that was released on Niconico Douga.

As the song that sets the story in motion, it’s very popular among fans, and the scene where it plays is a memorable climax in the series.
