T-Square, stylized in all-uppercase T-SQUARE, is a Japanese jazz fusion band formed in 1976. They became famous in the late 1970s and early 1980s along with other Japanese jazz bands. They are known for songs such as "Truth", "Japanese Soul Brothers", "Takarajima", and "Omens of Love", among others.
During the first years simply The SQUARE was printed on the frontsides of their albums. After the renaming of the band to T-Square the imprint changed to T-SQUARE and their typical logo became a capital letter T printed over a red square. The logo has been modified several times, reflecting the change of band names such as T-Square alpha, T-Square plus.
"Truth" was used as the theme for Fuji Television's Formula One coverage from 1987 to 1998 and starting in 2012. Special arrangements of this song were used as the theme for Japan's F1 2001 to 2006.
The band has won, all told, 12 Japan Gold Disc Awards. In the 80s, "SPORTS", "Truth", "Yes, No", and even their "F1 Grand Prix" compilation album won Gold Discs in the Jazz-Fusion category. In the 90s, "Natural", "Impressive", "Human", "Natsu no Wakusei", "B.C. A.D." and "Gravity" all won Gold Discs.
