Aitakatta ~Hashira wa Naize!~ (会いたかった～柱はないぜ!～ I want to meet you ~there is no pillar!~?) is AKB48's first concert outside the theater. It was held at the Nippon Seinenkan (日本青年館?) and serialized into two CD/DVD versions: Normal and Shuffle.
- The concert ran over 1.5 hours past its scheduled finish time due to the individual members' long catchphrases.
- The concert venue has 5 times more seats than the theater, able to accommodate up to 1400 people.
- Because the concert was not a full house, the empty seats were covered so that they would not stand out.
