History

Founding as NTT Communications RFC

NTT Communications RFC was established in 1976 as the rugby football club of the Tokyo branch of Public Corporation (Den-Den Kōsha), the predecessor organization to the modern NTT Group, aligning with the company's initiatives to promote sports among employees for health, morale, and community engagement. This corporate-backed formation reflected Japan's emphasis on company-sponsored athletics, where teams like NTT's served as platforms for talent cultivation within the workforce. In its formative years, the team, operating initially as Den-Den Kōsha RFC and later NTT RFC, engaged in regional corporate competitions across , prioritizing player development through recruitment from company staff and graduates to build a cohesive unit tied to NTT's operational structure. Participation centered on lower-tier leagues, including the Kantō region's social person leagues, where the emphasis was on steady growth rather than immediate dominance, fostering skills in a semi-amateur environment. The corporate model allowed for balanced integration of rugby training with professional duties, promoting long-term loyalty and technical proficiency among players. Key milestones during the and underscored the team's consistency in lower divisions, particularly through strong showings in the annual NTT Rugby National Tournament, an internal corporate competition that highlighted regional representatives. As NTT , the club secured notable results such as 1st place in B Block in 1988, 2nd place in B Block in 1994, and 1st place in A Block B Part in 1996, alongside multiple top-five finishes in A Block throughout the decade. These achievements in the tournament, which drew from NTT's regional branches, demonstrated progressive improvement and established a foundation for competitive rugby within the Kantō area.

At the conclusion of the 2009–10 season, NTT Communications RFC secured promotion to Japan's Top League by clinching the Top East League title, marking their entry into the nation's premier professional competition for the 2010–11 campaign. This achievement followed a period of steady development in regional play, positioning the team among the elite clubs. Concurrently, the club underwent a to NTT Communications Shining Arcs, adopting the "Shining Arcs" moniker derived from NTT's corporate symbol introduced in 1999, which evokes imagery of light, arches bridging connections, and forward ambition in and beyond. The name change reflected the team's aspirations for growth and visibility in the professional era, aligning with the company's global outreach themes. During their Top League tenure from 2010 to 2022, the Shining Arcs established themselves as a consistent mid-table performer, frequently securing ninth-place finishes without capturing major titles or advancing to championship contention. For instance, in the 2012–13 season, they ended ninth on the table with a balanced record of wins and losses, demonstrating resilience in a competitive field dominated by corporate powerhouses. Similarly, the 2018–19 campaign saw another ninth-place result, capping nine consecutive years in the Top League and underscoring their stability amid fluctuating league expansions and relegation battles. The team relied on a mix of domestic talent and international recruits to maintain this positioning, though they never breached the upper echelons, often finishing outside the top eight that qualified for postseason play. The 2021–22 season stood out as the Shining Arcs' final year in the Top League before the league's restructuring into , with the team navigating a condensed schedule impacted by the ongoing while integrating high-profile signings to bolster their squad.

Urayasu D-Rocks entered Division 2 for the 2022–23 season, marking a period of adaptation under the new identity and structure. The team showed promise in the regular season but suffered a playoff defeat in the promotion/relegation matches, remaining in Division 2 for another year and focusing on squad development to address inconsistencies exposed in high-stakes games.
