Operating rules (from the official website and documents)
Day-before setup
Usage time includes setup and cleanup time (price list). Hall rates are in 8-hour and 12-hour categories (the 24-hour column is "-"). Night-time or 24-hour use may not be available depending on the bookings before and after, so consult in advance. The official FAQ states that "except for some venues, the venue can be used 24 hours a day, 365 days a year." Advance arrival of packages is in principle designated as arrival on the day before the event, and an advance load-in notice must be submitted at least 1 week before the load-in date (valuables are not accepted, and no responsibility is taken for damage to packages). In principle, up to 5 boxes per hall are received as advance-arrival packages. Large quantities or large packages not notified in advance are treated as renting the venue for a fee as a storage space. (Source: Hall price list updated July 3, 2026; Advance Load-in Notice; FAQ; Terms of Use 2026ver2 Article 20)
Source: bellesalle.co.jp (PDF)Load-in and load-out
If there is load-in/load-out, submit an advance load-in notice at least 1 week before the work date (the loading area cannot be used if it is not submitted). Delivery vehicles for load-in and load-out must enter and leave from the designated place within the usage time, and the venue may adjust load-in times and the like. Loading and unloading work is in principle limited to 1 hour. Load-in is from the B1F loading area (shared with the building). The load-in door is 1,000 mm wide x 2,600 mm high; the elevator (No. 10) has a door 1,000 mm wide x 2,600 mm high, and inside the car 2,000 mm wide x 2,050 mm deep x 2,700 mm high, with a load capacity of 2,000 kg. The on-site manager completes check-in procedures at the Sumitomo Fudosan Onarimon Tower 1F Service Center before starting work. The building entrance is open on weekdays 7:00-20:00.

Source: bellesalle.co.jp (PDF)Delivery vehicle rules
The loading area is used only for loading and unloading; if parking is needed, use an outside parking lot. When multiple vehicles are used, they share one vehicle's loading space in staggered turns. Illegal parking, parking outside the designated parking lot, and roadside parking around the building are strictly prohibited. Products, packing materials, decoration materials, trash and the like may not be left in the loading area during the usage period. If delivery vehicle traffic is expected to be congested, traffic staff are placed at the entrance and so on. The permitted dimensions of the loading area are 3,600 mm overall height x 6,000 mm overall length, for vehicles up to 2 tons (long vehicles not allowed). The vehicle limit in the equipment list is 3,600 mm high x 6,000 mm long, 2.0 t.
