GiGO Shinjuku Kabukicho

Open until 1am, which is rather the point of it. GiGO's Kabukichō arcade takes the bottom two floors of the Daini Toa Kaikan, three minutes from Seibu-Shinjuku Station, and it's still going long after the Akihabara branches have closed. (GiGO)

No retro floor here — for that you want Building 3 in Akihabara. The second floor is GiGO Poker, an amusement poker room that reopened in December 2025. (GiGO, GENDA GiGO)
