OMM Building in Osaka's Temmabashi offers excellent access and versatility with its rental office and commercial space, exhibition halls and conference rooms. It comprises 11 halls of varying size, 9 conference rooms with capacity ranging from 12 to 500 persons and a gallery, all of which are available for trainings, seminars and presentations. The conference rooms are conveniently located on the same floor as the exhibition halls. Facilities are good and offered at reasonable rates. The building's excellent business support, with the medical center, and postal services available under one roof, and its range of tenants including offices and apparel companies and restaurants, make the entire building a source of business information. The building enjoys the environmental advantage of a waterfront location with plenty of greenery, as it fronts the Okawa River and is close to both Osaka Castle and Nakanoshima Park. It is also close by the Osaka Prefectural Government offices, the Joint Government Building and other public offices. The second basement level has direct connections to the Keihan Line and Osaka Metro Temmabashi Stations, and this superior traffic access is another feature that adds drawing power to the complex.
