Source-derived summary

Toshiya Sukegawa (Japanese: 助川 敏弥, romanized: Sukegawa Toshiya; 15 July 1930 – 26 September 2015) was a Japanese composer, music critic and magazine editor.

Biography

Born in Sapporo, Sukegawa entered the composition department of Tokyo University of the Arts in 1952, where he studied with Tomojirō Ikenouchi, graduating in 1957. While still a student he won first prize and a special prize in the composition division of the Music Competition of Japan in 1954 with his Passacaglia for Orchestra.

In 1958, he joined Yagi No Kai (the Goat Group), a group of Japanese composers including Hikaru Hayashi, Michio Mamiya, and Yuzō Toyama. The Goat Group sought to create distinctively Japanese music assimilating Japanese folksongs and traditional music into the western art music in which they had trained.

Alongside his concert works Sukegawa wrote extensively for broadcasting, particularly for NHK. He received an Encouragement Prize at the Ministry of Education Art Festival in 1960 for his Partita for Orchestra and an Excellence Prize from the Agency for Cultural Affairs Art Festival in 1971; in 1973 the NHK entry Children and Words, which he composed, won the Prix Italia. He later taught at the University of Tokyo and served as representative director of the Japan Music and Dance Conference and as editor-in-chief of its journal Ongaku no Sekai ("The World of Music").

Sukegawa died of lung cancer in Tokyo on 26 September 2015, at the age of 85.

Works

Sukegawa composed music for most western art music instruments, including orchestra, piano, and marimba, as well as electroacoustic music. His early output consists largely of orchestral and chamber works, beginning with the Passacaglia for Orchestra (1954); after entering the world of broadcast music he broadened his output to include choral works and pieces for traditional Japanese instruments, and from the 1970s onwards concentrated particularly on piano music.

Editorial summary

Begin with the source’s own compact description: “Toshiya Sukegawa” is japanese composer (1930-2015). The dossier treats that line as a proposition to test through Toshiya, Sukegawa and Japanese, not as a finished interpretation.

Editorial reviewA useful biographical orientation record, particularly for establishing names, roles and a first chronology. The current lead gives the account dated anchors—1930, 2015, 1952, 1957—that can be checked directly. The linked authority record independently contributes the date 1930-07-15. For this dossier, Toshiya, Sukegawa and Japanese is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “japanese composer (1930-2015)” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

The entry’s evidential value lies in the named roles, institutions and publications that can be tested against primary documentation. The source revision retrieved here is dated Aug 18, 2026. The linked authority identifier is Q11399809. VIAF identifies the subject as 114893216. The Library of Congress control number is nr96032632. 3 of 5 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1930, 2015, 1952 and 1957.

Critical limits

Later biographies can compress uncertainty and repeat inherited reputations, so apparently settled claims may still require comparison. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
