Can anyone explain this with the stages for me? I've searched like everywhere but can't find any answer.
Maybe I'll try to answer this too.
Actually you can get some clue in AKB48's official website.
AKB48 is kind of theatre group. They perform every day. That's how they gain singing, dancing... all kinds of performing experience from. They name performace as 'stage'. So 1st stage means '1st performace'. For example, for Team A, 1st stage performace 'Party ga Hajimaru yo" starts from 2005.12.28 to 2005.3.31. Then 2nd stage performace 'Aitakatta' starts from 2006.4.15 to 2006.8.11, with totally new songs. So you know AKB48 includes 3 teams namely Team A, K and B. Team A is the first team formed so that they perform the earliest. You can see from AKB48's official website that Team A is currently performing 4th stage songs while Team K is performing 3rd stage songs.
