NTT Communications RFC was founded in 1976. They won promotion to the expanded Top League of 14 teams at the end of the 2009–10 season. They made their Top League debut for the 2010–11 season. After their first season, they finished 12th place with 4 wins and 9 losses. They had to play a play-off to keep themselves in the Top League, in which they beat Canon Eagles 31–19. In the 2011–12 season, they finished in ninth place.

In July 2022, following the establishment of a new rugby business and sports company by parent company NTT, the Shining Arcs formally rebranded to the Urayasu D-Rocks.[3] The new company, NTT Sports X, was established at the end of the 2022 season and is alleged to have begun with JP¥2.5 billion (US$17.8 million) in capital.[5]
