Operating rules (from the official website and documents)
Load-in and load-out
The loading dock is on B2F. Vehicles up to 2,300 mm wide x 8,700 mm deep x 3,200 mm high can enter. It is available 24 hours, but the shutter is closed from 1:00 to 5:00, so an application is required. Use the hall's dedicated freight elevator (3,000 mm wide x 6,000 mm deep x 3,000 mm high, load capacity 10 t, vehicles can be carried in) to go up to the 3rd floor, where the hall is. The diagram marks "card key required" in front of the elevator. The load-in and load-out schedule is decided at the final meeting 2 weeks before the event. When using incidental equipment, hold a meeting with the operator on the load-in/out plan and other documents at least 1 month before the first day of use. (Source: Load-in Route Diagram as of November 2024, Facility Overview as of September 1, 2021, Steps Before Use, Terms of Use revised March 20, 2024). For advance mailing of packages, send them with arrival specified for the day before the use date. Packages that arrive before the day before cannot be stored.

Loading vehicles cannot enter B3F (the ceiling height is 2.9 m, so there is a risk of contact). You cannot go down directly from the B2F loading dock to the B3F parking lot; exit once and enter again. Parking bicycles, motorcycles and cars on the street at or near the hall is prohibited by the terms of use. (Source: Load-in Route Diagram as of November 2024, Terms of Use revised March 20, 2024)
