by It’s been almost a month since the 2025 Summer anime season began. TV anime appeals not only for its main story but also for its theme songs, which condense the world of the series into 1 minute and 30 seconds. This season also boasts a diverse selection of songs. Which theme songs have captured fans’ hearts? So, Anime! Anime! Conducted a reader survey titled “Which Summer 2025 Anime Opening Theme Songs Are Your Favorite?” We received 106 responses from July 30th to August 5th.

The story begins with a collection of classic opening songs! The top spot goes to “Toilet-Bound Hanako-kun 2” (sequel). The support rate was approximately 12 percent. The opening theme for this series is “Kagome Kagome” by Masayoshi Oishi. “Oishi, who has worked on opening themes throughout the series, has once again skillfully integrated the world of ‘Hanako-kun’ into the lyrics and melody. The scene where the phrase ‘Kagome Kagome’ plays in particular gave me goosebumps!” and “It gets your imagination flowing with the story this season, and it’s wonderful how it conveys the atmosphere of the characters. I’m even more curious to see what happens next.”
The song received high praise for its closeness to the series. Second place was tied between “Rent-A-Girlfriend Season 4” and “Ruri no Houseki.” The support rate was approximately 7 percent. The opening theme for “Rent-A-Girlfriend” is “Umitsuki” by ClariS. Readers also expressed support for their new start as artists, saying, “The fairy-tale-like visuals and ClariS’s crystal-clear vocals combined to draw me into the world of the story,” and “This is ClariS’s first anime song, now a trio, and the clarity is a perfect fit for ‘Kanojo, Okarishimasu.’ It’s truly amazing how they can create masterpieces no matter what work they collaborate with.”
The opening theme for “Ruri no Houseki” is Rei Yasuda’s “Hikari no Sumika.” Some readers commented that the song beautifully captures the theme of the work, saying, “Her mystical vocals are like the ores that have been created over tens of thousands of years, conveying a message from the Earth. It resonated with me,” and “The story depicts a journey of mineral collecting, and the beauty of the ores is impressive, as are the magnificent natural scenery, such as rivers and caves. I was moved by the song, which even feels like the breath of the Earth.”
Here are some other comments! Regarding “Suffer” by Okazaki Taiiku from “What a detective these days,” he commented, “I was surprised by the unexpected lyrics, which suddenly change from a cool intro to one about the physical discomforts that only middle-aged people experience. It captured my heart in many ways.” Regarding “Osomatsu-san’s Bombache!” by DA PUMP, he commented, “The catchy tempo and cheerful lyrics that are so Osomatsu-san-esque are the best! The opening animation, with the sextuplets surrounded by beautiful women in swimsuits to the rhythm of DA PUMP, is also impressive.”
Regarding “Seishun Eien” by Shonan no Kaze feat. Atarashii Gakkou no Leaders from “Grand Blue Season 2,” he commented, “Following on from the first season, Shonan no Kaze will heat Grand Blue! And with the addition of Atarashii Gakkou no Leaders, the youthfulness is doubled!! Another great song you’ll want to listen to in the summer has been born.” “Super Big Love!” by Tenrougun from “Bad Girl” received votes for a wide range of titles, with comments such as “It’s an opening theme packed with the cuteness that’s so characteristic of Kirara anime.
The dance is sharp from the start! The fast-paced ending with a full-speed dash is irresistible.” This season, theme songs from a variety of genres, including comedy, horror, and action, have been ranked. Titles that are synchronized with the opening theme anime are especially popular.
