Sony Sendai was founded in 1968 and for much of the team's history it remained a small company club representing only the Sendai branch of Sony Corporation. Playing in the Miyagi Prefectural League, they received little attention from head office. With the formation of the J-League in 1993, however, a five-year plan was introduced by club management, which aimed at strengthening the team within the JFL. The following year, Sony Sendai won the Prefectural League title to gain promotion to the regional Tohoku League and by 1997, had claimed three consecutive Tohoku League championships. Indeed, so dominant was Sony that in 1997 it finished with a victory margin of nineteen points over Morioka Zebra and TDK Akita -- not bad for a fourteen-match season! The team was clearly ready for a new challenge, and in 1998 Sony Sendai took its place in the JFL.

The team's performance in the JFL since 1998 has been somewhat inconsistent, but generally speaking it has established itself as a top-half team. The best finish to date came in 2002, when Sony finished fourth. At the beginning of 2005, Sony got off to a flying start, winning the first six matches of the season. But as the year wore on they were overtaken by others, and continued slipping down-table to finish seventh. The team generally attracts around 500 fans to home matches, suggesting that Sony would have a difficult time meeting the requirements for J.League admission. However, the parent company has long maintained the intention of keeping Sony Sendai as a completely amateur, company team. This probably is for the best, since the team shares its home town with the wildly popular J2 team Vegalta Sendai. It is unlikely that the team will join the competition for a J.League spot in the foreseeable future.
