Comparable Halls


Which is more appropriate for a 1000-person function, the Main Hall or the Annex Hall?

The Annex Hall holds 1000 people, and has an exclusive entrance and lobby, ensuring a higher degree of autonomy than the Main Hall. However, the Main Hall is more suitable for performances using video, lighting, or stage equipment. We can provide proposals for attractions, video and lighting plan, stage decoration design, and more.
*Our designated contractor will operate the equipment.

Which is more appropriate for a musical event or concert, the Main Hall or the Event Hall?

The Main Hall allows simple musical or dance performances for opening ceremonies, etc., but it utilizes a sound system that is generally more suitable for speeches and conferences than music. Furthermore, the stage depth is 8 m, and the stage floor is carpeted.
The Event Hall is a pillar-less space of 3,000 ㎡, and you may install a temporary stage or speaker system if desired. It also has a stage with elevating platform in the back of the hall.

How many front-row seats with tables and back-row seats with side tables are there on the 1st floor of the Main Hall?

400 seats each. The Main Hall may be used for 400-person events as well.

Are the Main Hall seats numbered?

The seats are not numbered. If you wish to have assigned seats, you may use stickers, as long as they do not leave marks and you make sure to remove them after your event.

Can a reception area or display booths be installed in the Main Lounge in front of the Main Hall?

Yes, but we recommend that you hold your reception in the main entrance corridor for security and traffic flow reasons.
You may install displays in front of the stained glass between the entrances on either side of the Main Hall, or in the space with hexagonal seats, but you are required to inform our sales staff in advance.

When using the Main Hall, where is the most convenient location for VIP waiting rooms, secretariats, or headquarters?

Located close to the stage wings, Rooms 158, 159, and 160 are convenient for VIP waiting rooms, and Room 157 is convenient for your secretariat.
