Load-in and load-out
Reception for the loading area is 7:30-19:00 on weekdays and 9:00-17:00 on Saturdays. Outside these hours the loading-area shutter is closed, so call the Conference Center (03-6206-4855) and a staff member will come to meet you. An advance application form is required to use the loading area and the load-in/load-out elevator; submit it through the application form by 3 days before the date of use (if the day 3 days before falls on a Saturday, Sunday or holiday, by the preceding weekday). The load-in elevators (No. 25 and No. 26) have a maximum load of 1,700 kg, a car size of W1,400 x D2,000 x H3,000 mm and a door size of W1,400 x H2,500 mm.

Organizers cannot bring in, arrange or serve food and drink themselves; request it through the operator's partner vendors (the usage rules also prohibit bringing in food and drink from anyone other than the operator-designated vendors). Individual participants may bring in their own. For boxed lunches and social gatherings, you receive proposals from several partner vendors to match your needs and budget, and then arrange it. If any participants have allergies, tell the venue in advance and you will be told which vendors and methods can accommodate them (usage rules as of June 1, 2026).
Source: solacity.jpRestaurants in the venue or building
There are restaurants on the B1 floor of sola city and in WATERRAS Mall (a restaurant district on floors 1 to 3), which is connected by the B1 passage. The official website introduces cafes and restaurants in the same building and nearby as places to use before and after events and for after-parties.
