However, it changed suddenly in 1993 when they embarked on a challenging task to reach the former Japan Football League within 5 years.

As a result of the 2011 Tōhoku earthquake and tsunami, Sony Sendai, with permission from the JFL, did not contest the first half of the 2011 season.

They expectedly earned last place on points, but due to Machida Zelvia and Matsumoto Yamaga being promoted to Division 2 and JEF Reserves withdrawing from the competition, they were spared relegation.

On 27 September 2024, Sony announced the dissolution of the team, effective at the end of the 2024 JFL season, after fifty-six years of existence.
