The Orix Buffaloes and Seibu Lions will have a three game match from April 22nd ~ 24th at Kyocera Dome in Osaka. It has been reported that 9 member Korean girl group, SNSD will be in attendance.
Orix players Lee Seungyeop (34 y.o infielder) and Park Chanho (37 y.o pitcher) are from Korea, so SNSD will be attending to support them. The members of SNSD are scheduled to visit during any of those three matches and will be singing the Korean national anthem during the opening ceremony of the match. It seems that April 23rd seems the most likely date for SNSD to attend.
