Operating rules (from the official website and documents)
Day-before setup
Usage time includes setup and cleanup time (price list). The hall rates are for 8 hours and 12 hours (the 24-hour column is "-"), and the conference room rates are for 4 hours, 8 hours and 12 hours. Night-time use of the hall may not be available depending on the bookings before and after, so consult in advance. Advance arrival of packages is in principle specified 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 the operator takes no responsibility for damage to packages). Large quantities of packages or large packages that have not been notified in advance are treated as renting the venue for a fee as a storage space. (Source: 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 or load-out, an advance load-in notice must be submitted 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 within the usage time from the designated location, and the venue may adjust load-in times and the like. The loading area is on the 1F, and loading and unloading work is in principle limited to 20 minutes. The permitted dimensions of the loading area are 3,000 mm total height x 6,000 mm total length (including when the gate is lowered).

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 and roadside parking around the building outside the designated parking lot are strictly prohibited (roadside parking around the building is grounds for cancellation of the usage contract or suspension of use). 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 similar points. The vehicle restriction in the facility list is 3,000 mm high x 6,000 mm long, weight 2.0 t (including when the gate is lowered). Bellesalle's dedicated parking lot has 1 space, and leaving a vehicle parked is allowed (advance reservation required).
