West Japan General Exhibition Center is only a 5 minute walk from JR Kokura Station North Exit.

The center consists of two buildings: the Main Building, which has an area of 7,000m², and the New Building, which has an area of 8,000m². Both buildings provide a vast open space that can be divided into partitions according to the nature of the event.  The kinds of events held here include anything from entertainment, such as game or character shows, to trade fairs, exhibitions, bazaars, fairs, and flea markets. The 3^rd floor of AIM also has an exhibition hall and meeting rooms.

For some events, stalls are also set up in the space between both buildings, and the whole area becomes bustling with visitors.
