The Astor Ballroom is the city's most prestigious venue for meeting, banquet, conference, and social galas. Hand crafted ceilings and crystal chandeliers create a magical atmosphere that is both majestic and intimate in the same instance.
High 3.5-meter ceilings illuminated with contemporary crystal chandeliers, accents of silver leaf in a deep corniced ceiling, and wall paneling in light celadon green tones are among the elegant details that define the Astor Ballroom. This grand event space in Osaka can be easily divided into two 105-square-meter rooms.
On one side, drapes open to stunning views north along Midosuji Boulevard looking toward Osaka Central Station. On the other, a mantle and fireplace feature topped by a large mirror gives the room a warm and welcoming ambiance.
Overlooking Midosjui Avenue through floor-to-ceiling windows under 3.5-meter ceilings, the Founder Suite is a supremely tailored room decorated in neutral tones with rich wood accents. It includes a fireplace and mantle feature topped by a round mirror, crystal chandeliers.
