In the same year he scored the original Japanese version of Gulliver's Travels Beyond the Moon, but the film was re-scored by Milton DeLugg when it was dubbed into English.
The album featured electronic renditions of contemporary rock and pop songs, while utilizing speech synthesis in place of a human voice.

[14] 1978's Kosmos featured his renditions of Arthur Honegger's Pacific 231, Charles Ives's The Unanswered Question and the Star Wars theme.
He credits himself with "The Plasma Symphony Orchestra", which was a computer synthesizer process using the wave forms of electromagnetic emanations from various stars and constellations for the sonic textures of this album.
He gave a big concert in 1984 at the annual contemporary music Ars Electronica festival in Linz, Austria called Mind of the Universe, mixing tracks live in a glass pyramid suspended over an audience of 80,000 people.
His last SoundCloud event was in Nagoya, Japan in 1997, featuring guest performances by The Manhattan Transfer, Ray Charles, Dionne Warwick, and Rick Wakeman.
In the late 1990s, he composed a symphonic fantasy for orchestra and synthesizer titled The Tale of Genji, inspired by the eponymous 11th-century Japanese story.

In 2012 Tomita performed Symphony Ihatov in Tokyo, directing the Japan Philharmonic, an accompanying choir, and featuring cyber-celebrity/diva, Hatsune Miku, a digital avatar created by the Japanese company Crypton Future Media.
The same year, in recognition of his long career and global influence on electronic music, Tomita won the Japan Foundation Award, an award launched "to honor individuals or organizations who have made a significant contribution to promoting understanding and friendship between Japan and the rest of the world through academic, artistic and other cultural pursuits".
