Where Our Blue Is[a] (青のすみか, Ao no Sumika; lit. 'House of Blue') is the third EP by Japanese singer-songwriter Tatsuya Kitani. It was released on July 19, 2023, by Mastersix Foundation. The title track serves as the third overall opening theme song for the Jujutsu Kaisen anime television series.
Overview
[edit]It was released in two editions: the standard edition and the first press limited edition.[1] The standard edition includes the title song, the self-cover version of the song "Love Song (featuring Eve)", and two other tracks.[1] The first press limited edition includes the DVD of the live performance of the one-man tour "Unknot/Reknot" held at Zepp DiverCity (Tokyo) on October 15, 2022.[1] On June 26, the EP was available to pre-order on iTunes and pre-add or pre-save on Apple Music and Spotify. While the standard edition features a cover of two hands touching one another, the first press edition front and back covers show Jujutsu Kaisen character Satoru Gojo and Suguru Geto instead. Anichoice praised the design of the cover.[2]
The title track "Where Our Blue Is" was pre-released as a single worldwide on July 7, 2023.[3] It peaked at number two in the Billboard Japan Hot 100,[4] the Billboard Japan Download Songs chart,[5] and the Billboard Japan Streaming Songs chart.[6] The music video for it was released on YouTube on July 13, 2023.[7] It was filmed in the desert of Dubai.[8]
Composition
[edit]The song is based on the concept of "farewell peculiar to youth". In producing the music, Kitani received an offer from the anime production side, "A song with a refreshing impression based on the theme of youth". He said it was difficult. The school chime (Westminster Quarters) phrase is used in part of the song. Revealing the changes that have sprouted in order to save memories of youth and "deliver".[9]
Kitani was able to quickly create something like the first seed for "Where Our Blue Is", but it was difficult after that. The first arrangement of this song was completely different, with a slower BPM, more sad elements, and a bit of a guitar on a club beat. The singer tried to make a version that was closer to that, and what he came up with was a guitar rock with a fast BPM and a sense of speed. When asking the director to listen to those two, he said, "It's about the middle." After all, the melody and lyrics are the same, but the finished product is different. Eve's "Kaikai Kitan" was a major inspiration for the song. "Scar", which he wrote as the first opening theme song for the Bleach: Thousand-Year Blood War anime television series, is one of them, and when he was writing the chorus of "Where Our Blue Is", Kitani was thinking about that. Straight as much as possible, twisted in other places. At the beginning of the song, there is a sound like "Corn!" which makes the listener feel like they are back in the womb. When people put in that kind of sound effect to attract the listener and help them grow up.[10]
For Jujutsu Kaisen, the video primarily deals with the youth of Gojo and Geto, with an emphasis on blue backgrounds, like the lyrics say. The opening contrasts with the ending theme, "Akari", which uses a more relaxed melody and also makes emphasis on Gojo and Geto's friendship. Collab Cafe praised the opening as it will make people listen to it several times.[11]

Background and release
Development and recording
Tatsuya Kitani opted to release his third EP, Where Our Blue Is, building on the momentum from his prior releases including the 2020 album DEMAGOG and the 2022 album BIPOLAR, amid a burgeoning fanbase and his intent to further explore poignant emotional landscapes centered on loss and emotional sanctuary.[6] The project marked a significant personal milestone, drawing from Kitani's established role as a composer for anime soundtracks, such as his contributions to Jujutsu Kaisen Season 1 with "Kaikai Kitan," which influenced the stylistic and thematic approach here.[7] Songwriting for the title track commenced in early 2023 following an offer from the Jujutsu Kaisen production team to craft an opening theme evoking youth and farewell, with the full EP wrapping production by mid-2023 to align with the anime's airing schedule.[6] Recording took place throughout 2023 at various studios in Tokyo, where Kitani closely collaborated with producers affiliated with Sony Music Labels Inc.—responsible for the lead single—and his own label, Mastersix Foundation, which handled the EP's overall release.[8] Kitani's hands-on involvement extended to writing, composing, and arranging the core tracks, including revisions to the title track based on feedback from anime directors to balance its refreshing tone against the series' darker narrative.[9] This process emphasized conceptual depth over rapid execution, with early demos evolving through iterative sessions to capture the EP's introspective essence. The EP's completion in mid-2023 paved the way for its July 19 launch, shortly after the title track's digital single debut on July 7.Promotion and release formats
The EP Where Our Blue Is was officially released on July 19, 2023, through Sony Music Labels Inc. and Mastersix Foundation, with distribution handled by Sony Music Solutions Inc..[10][11] The title track was made available as a digital single on July 7, 2023, ahead of the full four-track EP, allowing early access via major streaming services. Promotional efforts began with teaser trailers uploaded to YouTube on July 6, 2023, featuring the title track audio to build anticipation.[12] Social media campaigns emphasized the EP's connection to the Jujutsu Kaisen anime, capitalizing on fan excitement for the series' second season.[10] Tatsuya Kitani conducted live preview performances in Japan, including a release memorial acoustic set at Tower Records Shibuya on July 20, 2023, to engage audiences directly.[13] The EP was offered in multiple formats to cater to both domestic and international markets. Digital downloads of the four tracks were available globally on platforms such as Spotify and Apple Music starting July 19, 2023. In Japan, physical options included a regular CD edition priced at ¥1,980 (tax included), containing the tracks plus an instrumental version,[1] and a limited edition CD bundled with a booklet and Blu-ray disc of live footage for ¥5,500 (tax included).[14] These partnerships with Sony ensured wide availability, positioning the release to leverage the anime tie-in for enhanced market reach.[11]Music and lyrics
Composition and style
Where Our Blue Is is an EP by Japanese singer-songwriter Tatsuya Kitani that blends alternative rock with J-pop elements, characteristic of his broader musical style which also incorporates funk, R&B, and hip-hop influences.[15][16] The title track features dynamic builds driven by guitar riffs and electronic synths, creating an energetic soundscape suited for its role as the opening theme for Jujutsu Kaisen season 2. Instrumentation includes piano performed by Tetsuya Hirahata and drums by Osamu Hidai, alongside Kitani handling arrangement and other instruments.[17][18] The production emphasizes layered vocals by Kitani, enhancing the emotional depth, with the track produced by Kitani himself under Sony Music Labels Inc.[19] The title track maintains an upbeat tempo of around 150 BPM in the key of D-flat major, contrasting with the slower, more introspective B-sides such as "Have a nice end!" and the cover of "Love Song".[20][21] This EP reflects Kitani's evolution from minimalist Vocaloid productions to richer, orchestral-tinged arrangements, building on his previous works like BIPOLAR.[22]Themes and title track analysis
The EP Where Our Blue Is explores core themes of finding emotional refuge in memories of youth amid inevitable loss and change, with "blue" serving as a central metaphor for a sanctuary of clarity and solace that persists despite life's hardships. This refuge is depicted as an internal space where individuals revisit bittersweet experiences to heal and grow, drawing from the pain of separation and the beauty of transient joys. The narrative draws inspiration from personal reflections on adolescence and broader anime motifs of hidden, idealized worlds that offer escape from reality's cruelties, as seen in the Jujutsu Kaisen arc's portrayal of youthful bonds shattered by fate.[23][24] The title track, "Ao no Sumika" (translated as "Where Our Blue Is"), structures its lyrics to build emotional intensity through verses that evoke nostalgic scenes of endless blue seasons and unspoken connections, culminating in a chorus that affirms resilience: "Even now, blue resides / Even now, blue remains clear." These verses paint vivid imagery of four aligned eyes witnessing an unobstructed horizon, symbolizing unfiltered youthful perception, while the chorus shifts to introspection on prayers and words that approach but never fully connect, underscoring themes of longing and persistence. The song's progression mirrors a journey from vivid recall to quiet acceptance, with lines like "Like the grains of a star of this infinitely expanding universe / You slip through my fingers" highlighting the ephemerality of relationships.[25][26] Symbolically, "blue" represents not only the vibrancy of youth but also an unattainable peace and emotional clarity that endures as a mental haven, even as external realities erode connections and impose loss. This motif ties into the EP's broader narrative of introspection, where revisiting "blue" memories provides healing for adult anxieties, contrasting the chaos of growth with moments of serene refuge. In interviews, Kitani revealed that the track's inspirations stem from his own everyday anxieties and emotional fluctuations, channeled into lyrics that capture universal feelings of nostalgia and human imperfection to foster listener connection. He aimed to blend personal vulnerabilities with the Jujutsu Kaisen storyline's exploration of flawed bonds and tragic growth, creating a piece that resonates as both intimate diary and shared lament.[23][24]Critical reception
Reviews and acclaim
Upon its release in July 2023, "Where Our Blue Is" received widespread praise from Japanese music critics for its emotional depth and Tatsuya Kitani's compelling vocal delivery. Rockin'On Japan highlighted how the track masterfully intertwines feelings of loneliness, affection, anger, confusion, and determination, describing it as a poignant exploration of irretrievable relationships that enriches the listener's emotional experience.[27] Similarly, Skream! commended the song's nostalgic lyrics and school chime-inspired scat, positioning it as a fragile anthem of youth that resonates deeply with fans of the anime and personal reflections on adolescence.[28] Otowatashi noted the refreshing guitar rock arrangement, incorporating claps, choral elements, and dynamic melodies to evoke the bittersweet duality of cherished memories and lingering regrets in youth.[29] Critics also appreciated Kitani's precise vocal performance, which balances intensity without excess, allowing the lyrics—such as "きみと違う僕という呪いが肥っていく" (a curse of difference growing between us)—to convey introspective resolve and relational inevitability.[27] In a 2023 interview with Xtrend, Kitani reflected on the track's replay value, explaining how incorporating nostalgic school chimes and adjusting the tempo enhanced its fresh, uplifting sound while wrapping heavy themes in accessibility, contributing to its enduring appeal among listeners.[30] Western anime outlets acknowledged the song's strong thematic alignment with Jujutsu Kaisen's Hidden Inventory arc in coverage tied to the series' premiere. While the title track garnered acclaim, the B-sides include the upbeat "Suteki na Shūmatsu o!" and a cover of "Love Song" by Kirinji. Aggregated scores from music platforms averaged around 8/10, reflecting broad approval tempered by occasional notes on the EP's reliance on anime-tie-in tropes.[31] The single's reception evolved from initial digital buzz on July 7, 2023—aligning with the anime's season 2 debut—to heightened enthusiasm as episodes aired, amplifying its emotional resonance within the series' narrative.[32] This positive critical foundation contributed to subsequent recognitions in anime music categories.Accolades and awards
"Where Our Blue Is" received significant recognition in the anime music community, highlighted by its success at major international awards ceremonies. The track won the Best Opening Sequence category at the 2024 Crunchyroll Anime Awards, praised for its emotional depth and synergy with the visuals of Jujutsu Kaisen Season 2.[33][34] This accolade stemmed from the song's critical praise for capturing the arc's themes of loss and resilience, contributing to Jujutsu Kaisen Season 2's sweep of eleven awards overall at the event.[35]| Ceremony | Year | Award | Result | Ref. |

Role in Jujutsu Kaisen
"Where Our Blue Is" was selected by the anime's production studio MAPPA and music distributor Sony Music Labels as the opening theme for the Hidden Inventory arc in Jujutsu Kaisen Season 2. The track premiered alongside the season on July 6, 2023, and featured in episodes 25 through 29 of the series overall.[49] The song's lyrics resonate with the arc's central themes, evoking the intimate bond and shared sanctuary between Satoru Gojo and Suguru Geto amid their high school days as sorcerers, where "blue" symbolizes Gojo's striking eyes and their idealized world as an emotional refuge from external conflicts.[25] This alignment underscores the narrative's focus on youthful camaraderie, hidden potentials, and the bittersweet undercurrents of their diverging paths.[50] The opening sequence vividly captures these elements through fluid visuals of Gojo and Geto in action, interspersed with symbolic imagery of blue hues and sorcerer domains that foreshadow the arc's emotional depth and key confrontations.[51] Its role significantly amplified the season's success, contributing to record viewership highs on streaming platforms and earning acclaim as the top anime opening of summer 2023. A creditless version was officially released in July 2023 to further engage fans.[52]Acoustic version and adaptations
In 2025, Tatsuya Kitani released an acoustic rendition of "Where Our Blue Is" as the theme song for the Jujutsu Kaisen compilation film Hidden Inventory / Premature Death, which recaps the anime's second season arc.[53] The version debuted in the film's first trailer on March 22, 2025, at AnimeJapan, where its stripped-down arrangement—featuring only acoustic guitar and Kitani's vocals—amplified the emotional depth of the story's reflective tone.[53] This adaptation, titled "Where Our Blue Is (Acoustic version)," was officially released as a digital single on May 30, 2025, via Sony Music Labels Inc., running approximately 3 minutes and 24 seconds.[54] The film grossed about $9.3 million worldwide as of November 2025, further boosting the song's popularity.[55] Earlier adaptations emerged shortly after the original track's 2023 debut as the opening theme for Jujutsu Kaisen Season 2. In August 2023, Kitani performed a live rendition on THE FIRST TAKE, a popular YouTube series known for one-take recordings, capturing the song's raw intensity with minimal instrumentation and garnering millions of views.[56] By August 2024, electronic producer Alex Kade released a big room and future bass remix, transforming the track into an upbeat dance version available on streaming platforms, which highlighted its versatility for club and remix culture.[57] The song's enduring appeal led to its inclusion on Kitani's debut album ROUNDABOUT, released January 10, 2024, where the original version appeared as a key track amid new material, solidifying its place in his discography.[58] Fan communities have further extended its legacy through numerous covers, often shared on platforms like YouTube and TikTok, ranging from piano solos to orchestral interpretations that emphasize the lyrics' themes of loss and connection.[59]Content details
