Tsuburaya Productions and Toei Animation released a new teaser trailer and the third key visual for the 3DCG anime film Kaiju Decode: The Ring of Aidara on October 18, 2026. The update confirmed that the project is scheduled for a 2027 release in Japan.

This feature-length production follows the previous shorts in the franchise and introduces the lead voice cast. The film is set in Sakai City, Osaka Prefecture, in the year 2070, focusing on the relationship between a boy from a high-tech urban center and a girl from a monster-infested zone.

What We Know

Kaiju Decode: The Ring of Aidara (Japanese title: Kaiju Decode: Aidara no Yubiwa) is a co-production between Tsuburaya and Toei Animation. The animation production is handled by Arect and Toei Animation. The film is directed by S/N, who previously worked on the franchise's short films, with a screenplay written by Katsuie Shibata.

The project features a notable design team, including Masatsugu Saito (Xenoblade Chronicles) for the character Coco and Sei Nakashima for the character Maru. Masayuki Gotoh of Tsuburaya Productions is responsible for the monster designs. Producers Masahiro Onda and Kouichi Noguchi are overseeing the project. The teaser trailer also confirmed the primary voice cast: Aya Yamane will voice Maru, and Karin Takahashi will voice Coco.

Why It Matters

It builds upon the world-building established in a 2021 CG short film and a VR experience. By bringing together staff with expertise in both high-tech character design and traditional monster aesthetics, the production aims to expand the franchise for a worldwide audience.
