According to the AKB48 official blog, the 18+ age restriction to watch SDN48′s “Yuuwaku no Garter (誘惑のガーター)” theatre performance has been officially lifted.
With effect from 16 Jun 2011, fans that are below 18 years old will be able to attend the stage performance during the timeslots before 7pm. The age restriction will only apply to the shows after 8.30pm timslot. The tickets prices also appear to be different: 3,000 yen for 18+ shows and 2,000 yen for under 18 shows.
Anyway, I just managed to see the SND48 girls in action on Friday and they were really good. Hope that they do return back to Singapore for another performance soon.
