The Snowball Earth manga is in its final arc with over 1 million copies in circulation, while the anime's second season has been announced and merchandise lines are expanding. Kotobukiya's OSHI WORKS figures of Tetsuo Yabusame and Ao Nogi are available for pre-order.
The television anime adaptation of Yuhiro Tsujitsugu's manga Snowball Earth ran its first season on NTV's Friday night block starting April 3, 2026, produced by Studio KAI with Munehisa Sakai directing and Shigeru Murakoshi on series scripts. Viz Media publishes the English manga, which began in Shogakukan's Monthly Big Comic Spirits in January 2021. The season concluded with episode 13 on June 26, 2026, and a second season was announced the same day with a trailer. The finale drew criticism for a final boss fight that ended in under four minutes followed by a long slice-of-life epilogue.
Episode reviews traced a consistent problem: the villain Sagami's late sympathetic backstory across episodes 6, 9, 11, and 12 was called forced and illogical, while the CG animation for kaiju and action sequences was repeatedly criticized as awkward. A strong 2D shot of Ao atop her flaming chicken kaiju in episode 8 and fluid choreography in episode 7 were noted as exceptions to the show's uneven visual quality.
On the publishing side, the manga passed 1 million copies in circulation and entered its final arc, announced by Tsujitsugu on X with a celebratory illustration. The 12th compiled volume arrives September 30, and Viz Media publishes the 10th English volume on December 15. Merchandise has expanded: Kujibikido ran an online lottery from July 23 to August 20, 2026, with Japanese Modern themed visuals, and Kotobukiya opened pre-orders for two OSHI WORKS painted figures of Tetsuo Yabusame and Ao Nogi.

The television anime adaptation of Yuhiro Tsujitsugu's manga Snowball Earth has been renewed for a second season.

Anime News Network reviews episode 12 of Snowball Earth, criticizing a late-stage flashback sequence that attempts to humanize Colonel Sagami. The review argues the redemption arc feels forced and illogical, contrasting it with protagonist Tetsuo's more reasonable desire for a peaceful life. A kaiju reveal provides some payoff but stretches the series.
Episode 11 of Snowball Earth attempts to give villain Sagami a sympathetic backstory involving parental abandonment, but the review argues the late reveal does not make him more complex. Tetsuo, however, gets a strong character moment by directly confronting Sagami and ultimately transferring his savior role to him.
Anime Feminist reviewed the premiere of Snowball Earth, a series about a socially awkward boy named Tetsuo Yabusame who pilots a sentient mecha named Yukio to fight intergalactic monsters. The episode opens years after Tetsuo befriends the mech in his father's lab, then follows him on a disastrous mission where his crew and Yukio are destroyed. He returns to Earth to find the planet entering a new ice age. The review praises the setup of humanity being overwhelmed by monsters but criticizes the tonal disconnect between the harsh war reality and Tetsuo's humorous social anxiety struggles. It notes that Tetsuo's genius-level piloting ability feels anticlimactic, and his social awkwardness is his only trait, making him a generic wish-fulfillment protagonist. The reviewer found the mystery of mechanical failures on Tetsuo's ship and the cause of the ice age more compelling than his personal growth. The animation is described as decent, though CG for Tetsuo and monsters is distracting. The review compares the series unfavorably to Dead Dead Demons Dededede Destruction for balancing personal and global stakes.
The latest two episodes of the anime series "Snowball Earth" advance the siege on the survivors' hideout, a school building repeatedly called the Mishima Mall. Episode 8 follows Sagami and his subordinates as they close in on the hideout, which is protected by a barrier built by Hagane's mother. The episode is described as well-paced and tense, though the CG animation for the kaiju is criticized as awkward, with one bat kaiju's movements compared to a CG child throwing a tantrum. A standout 2D shot of Ao atop her flaming chicken kaiju at the end of episode 8 is praised for its color and intensity. Episode 9 continues the fight but is criticized for cutting away from the airborne kaiju battle to focus on Sagami's backstory, which the review finds unconvincing. The reviewer argues that Sagami's plan-slaughtering those who do not side with him to become a savior-makes him a weak villain, and the flashback meant to generate sympathy instead makes the worldbuilding seem illogical. The fight scenes are described as stretched out and interrupted by flashbacks and dialogue, creating narrative dissonance. The review notes that the show's inconsistent animation choices make the CG look worse by comparison, as brief moments of 2D animation tease a higher quality the series does not maintain.
Video Research released the Japanese animation household TV ratings for the Kanto region covering the weeks of May 11-17 and May 18-24. In the first week, Sazae-san led with a 7.1 rating, followed by Detective Conan at 6.5 and Chibi Maruko-chan at 5.1. The top ten also included Doraemon, Crayon Shin-chan, One Piece, Star Detective Precure!, Curious George, Oshiri Tantei season 10, and Bluey. The following week, Sazae-san remained on top at 6.9, with Detective Conan at 6.2 and Chibi Maruko-chan at 4.7. One Piece rose to 2.7, while That Time I Got Reincarnated as a Slime season 3 and Ascendance of a Bookworm Part 3 re-entered the chart at 2.6 and 2.5 respectively. Demon Slayer: Kimetsu no Yaiba rebroadcast tied at 2.3 with Crayon Shin-chan. Star Detective Precure! closed the list at 2.0.
Episode 6 of Snowball Earth reveals that antagonist Sagami's villainous plans stem from jealousy of a young child, Tetsuo. His backstory and motivations are laid bare, framed as childish and insipid. The episode also features poor CG animation and a retreat by Sagami's squad that extends the conflict for the remaining six episodes.
Episode 7 of Snowball Earth focuses on a fight between Sagami and the trio of Tetsuo, Yukio, and Hagane. The choreography is fluid and well-paced, and a brief moment of tenderness with Yukio's handmade loveseat offers a welcome break from the show's usually serious tone. However, the episode's reliance on CG animation undercuts the impact of key action sequences, creating a jarring contrast with the detailed 2D close-ups.
