Biography

Masayuki, credited then and now under the single mononym, is Yamaguchi Masayuki (山口正幸), born 3 January 1961 in Nagano Prefecture. He attended Tokyo Designer Gakuin's animation course, where he was a classmate of fellow future Gainax pillar Shoichi Masuo and Naohito Takahashi. After graduating he joined Studio Giants. The Sakuga Wiki notes that he decided to become an animator after watching Hayao Miyazaki's Future Boy Conan in high school.

Inside Giants his speciality was extreme wide-angle perspective drawings (広角パース). He has admitted in interviews, quoted in the Gainax Interviews collection, that he originally wanted to do Miyazaki-style action animation, but TV-series time and frame budgets at Giants would not allow it. So he reverse-engineered an approach: "how do I rise in this industry without the time and frame counts?" The answer was the dynamic extreme-angle action style that Yoshinori Kanada was pioneering at Toei, and Masayuki became one of its leading practitioners.

PAC's opening team, supervised by Kubo, brought him in. The brief was the entire 75-second sequence: storyboard, key animation, the lot. The finished opening is roughly 1,750 TV frames at the standard 24fps. According to a later technical breakdown by the OP's production team, all of the cuts in the opening are Masayuki's key animation except the Mumm-Ra cuts and effects, which had corrections applied in post. The Sakuga Wiki note adds: "his work on the ThunderCats OP caused a minor sensation inside the industry."

He moved to Gainax shortly afterwards, working on Royal Space Force: The Wings of Honneamise in 1987, the production where he befriended Hideaki Anno and, by his own account, sat down next to him and never really got up. The Sakuga Wiki has the story: Anno told animator Shinya Hasegawa during the production of Evangelion episode 9, in which Hasegawa was the animation director: "Masayuki's key animation, you either pass it through completely untouched, or redo all of it. Those are the only two options." Hasegawa's episode 9 went out largely untouched.

His Evangelion credits run continuously from 1995 to 2021: episode director and animator on the original TV series (including the iconic closing sequence); director on parts of Death & Rebirth and End of Evangelion (1997, where Anno made him 'Visual Water Artist' after he went to the beach instead of finishing his work); co-director, with Anno and Kazuya Tsurumaki, of all four Rebuild of Evangelion films through 2021's Evangelion 3.0+1.0.

Today he is 相談役 (sōdan-yaku, senior advisor) at Studio Khara, Anno's own studio. The ThunderCats opening was his first major credit.

On ThunderCats

Sole key animator and storyboard artist on the opening title sequence. ~1,750 TV frames in 75 seconds, on commission from PAC via Studio Giants. Animation supervised by Tsuguyuki Kubo. Per the Sakuga Wiki, all OP cuts are his key animation except the Mumm-Ra cuts and effects.

From the actual workbook

Studio Khara published two volumes of original keyframes from Evangelion: 3.0+1.0 (the final Rebuild film, 2021) under the title Shin Evangelion Theatrical Animation Original Drawings Collection. Masayuki is credited on the original-key-animation roster alongside Anno, Tsurumaki, Nakayama and the rest of the Khara core. The press kit released by Khara to Famitsu in 2022 included full-page samples of the interior pages. These are not literally photographs of Masayuki at his desk, but they are the next closest thing: the actual pencil-and-correction workbook that came off it.

Why this credit matters

Masayuki's ThunderCats opening is the strongest single argument for the \"the kids drawing this stuff in Tokyo were the future of anime\" thesis. He is now one of three names listed under directorial credit on what is widely considered the most ambitious anime franchise of the 21st century. He started here, on a loan-out job to an American children's show, at 23.
