Sunport Hall, which was created as a center for civic culture, is equipped with numerous cultural and convention functions, and a variety of events can be held here. With a maximum of 1,500 seats, the Grand Hall can be used for performing arts events, as well as conventions and meetings. Sunport Hall is also equipped with two smaller halls and 12 different-sized meeting rooms, as well as rehearsal rooms.

This is the ideal form of a convention center, including the multi-purpose space and large-scale tent area that sets the scene for vibrant events under the sun and sea breezes, the conference rooms that are equipped with world-class facilities and offer excellent views, and the Grand Hall where full-scale performing arts events can also be held.

Private meeting rooms, exhibition facilities, and media support facilities, which are all needed during an international conference, are located adjacent to compact areas. By partnering with surrounding facilities and networks, it is possible to carry out the smooth and efficient management of meetings.

It is possible to use this hall as a rental space for specific purposes, including the north hall for lectures and conferences, exhibitions, and parties, and teahouse in the courtyard. The north hall overlooks the northern garden that has a courtyard and lawn, which can be used for garden parties and events to enjoy the seasons in the elegant atmosphere of the outdoors.

Inside one of the famous most gardens in the world, the "Sanuki guesthouse" allows visitors to enjoy the traditional architectural techniques and styles of Sanuki during the Meiji era. This is where memories of warm hospitality is born.
