Vissel Kobe announced Monday that manager Ryo Adachi will step down from the helm with the expiration of his contract this season.

A successor for the 45-year-old Adachi has yet to be determined.

Adachi was promoted from head coach to manager of Vissel in November 2012.

He guided the club to second place in J2 with a record of 25-9 with eight draws to earn Vissel a promotion to the J. League first division for the 2014 season. So far this year, Vissel is 11-8 with 12 draws.
