His current pseudonym is derived from the pronunciations of the individual kanji that make up the compound for the Japanese word for "sushi."
His art style is largely influenced particularly from series Mobile Suit Gundam and Megazone 23, and fellow superiors in the industry, such as Tsukasa Dokite, Masamune Shirow, Masakazu Katsura, Kenichi Sonoda, and Masami Obari.
Tsukasa's 1990s anime style works are defined as wild, making the use of vivid colors and soft but stark contrasting shades, and somewhat exaggerated features of human anatomy along with realistic features, including that of puffed up cheeks, which he helped launch into popularity as they were in style at the time for defining cute characters and aesthetics.
[2] Into the current day, his style is defined by more subdued but more flowing coloring and an emphasis on darker and thicker lining work.
Outside of work in the anime industry, Tsukasa is a lifelong fan of Gundam and video games, particularly of King of Fighters and Pokémon.
