Anime songs that were hits in the 2000s: A nostalgic collection of god-tier tracks (21–30)
Song of LoveEvery Little Thing
The song that played over the ending of the feature film Inuyasha: The Castle Beyond the Looking Glass is a prayerful ballad that gently envelops the lingering emotions of its grand tale set in the Sengoku era.
Carried by Kaori Mochida’s crystal-clear vocals, the lyrics weave wishes for strength, flowers, and love—for the earth, the fields, and the heart.
While acknowledging one’s own weakness, it portrays a resolve to live for love from this very moment, mirroring the film’s theme of feelings that transcend time.
Included on the album Many Pieces, released in March 2003, its acoustic guitar and strings create an expansive sound that resonates deeply.
It’s a song that quietly gives you a nudge when you want to reexamine the bonds you share with someone dear.

This song, True Blue, was used as the opening theme for Astro Boy: Tetsuwan Atom, the third anime adaptation of Osamu Tezuka’s supreme Japanese manga, Tetsuwan Atom (Astro Boy).
As a theme for such a monumental work, it received worldwide acclaim.
It’s a popular track that has also been covered by a Taiwanese female singer.

The opening theme of the first cour, “INVOKE,” ranked second on the Oricon chart.
Go Tight!AKINO
Aquarion is a robot anime directed by Shoji Kawamori, who is famous for the Macross series.
The opening theme from the first season is probably better known, but I’d like to introduce the second season’s “Go Tight!” instead.
I think this is a great song as well.

“Full Metal Panic? Fumoffu” is an anime adaptation of the short stories from Shoji Gatoh’s novel series “Full Metal Panic!”.
The opening theme is “Sore ga, Ai deshou?” sung by Mikuni Shimokawa, released in September 2003.

This is “Issei no Koe,” used as the opening theme for the popular anime Natsume’s Book of Friends, known for its warm, yokai-themed storytelling.
Much like the show’s atmosphere, the song’s gently soothing melody leaves a lasting impression.
Highly recommended for those who enjoy bright, uplifting tunes.
