Judgement Day reached number 5 on both the Oricon and Billboard Japan charts, making it the band's highest-charting record to date.

[3] As soon as Fami was made a member, the guitarist sent her the digital data for the 10 songs on the album and asked her to record the bass parts in the following 2–3 weeks.

[6] Also returning, The EasyRabbit CreArtions, a duo of Spanish artists David López Gómez and Carlos Vincente León, provided the cover art.

[5] Asami, who worked on the song with the band's frequent collaborator Mao, said the first part sounds like thrash metal, but from there it develops in the "usual Lovebites way" and has the impact she expected after first hearing the riff.

[3] Believing thrash metal to be an essential part of the Lovebites sound, Asami cited "Dissonance" as her favorite track on Judgement Day.

Limited Editions A and B include a DVD or Blu-ray featuring a documentary on the auditions for a new bass player, the three songs Fami played with the band during the final selection, and the studio performance of "Bravehearted" which was used to reveal her as their new bassist.

[10] Victor released a limited edition 2-disc vinyl LP record version of the album, titled Ashita e no Sabaki (明日への裁き, "Toward Tomorrow's Judgement") in Japanese, on February 22, 2024, with new liner notes by Masanori Ito.

50 people who ordered the edition that features a t-shirt were randomly selected to receive a CD sleeve that was signed by the members of the band.

[20][21] Catherine Morris of Metal Hammer called Judgement Day a relentlessly fast-paced ode to the likes of Helloween and Stratovarius.

"[15] Dom Lawson of Blabbermouth.net gave Judgement Day an 8 out of 10 rating, writing that Lovebites "adhere to a more-is-more ethos, wherein speed, power and a never-ending stream of wild, technical solos are the keys to the kingdom.

With vocalist Asami scaling the octaves like some possessed Broadway star, every one of these songs is a full-on, no-holds-barred heavy metal rager".

[12] In an 8/10 review for Distorted Sound, Sam Khaneka wrote that while it is not very different from Lovebites' previous material stylistically speaking, they are tapping in to a more ferocious tone on the album.

He found this most-evident in the title track, where "battering ram guitar riffs, histrionic stabs of strings and looming background choirs" evoke a "classical nightmare".

Khaneka described the Baroque-infused synths on "The Spirit Lives On" as providing a counterpoint to the song's remorselessly fast rhythms while paving the way for some impressive vocal gymnastics in the chorus, and "My Orion" as the album's most direct track that leans more towards late 1980s pop metal.
