Official documents (floor plans, price lists, terms)

Operating rules (from the official website and documents)

Load-in and load-out

Load-in and load-out go from the loading area on B1F up to the 3rd floor by the freight elevator. Load-in and load-out is possible from 7:00 to 23:30. The elevator interior is W1,800 x D2,300 x H3,000 mm with a load capacity of 2,000 kg, and the door is W1,300 x H2,400 mm. A security card is required on the day, which the representative picks up at the hall office (3F). Load-in and load-out using the visitor elevators is prohibited. Floors, walls and similar must be protected. For advance procedures, write the items, times, vehicle size and number of vehicles on the load-in/out notice and submit it to the building through the person in charge at least 2 weeks before the event (the load-in route map says to contact the facility person in charge by 1 week before). The Operations & Preparation Q&A gives the load-in/out hours as "23:30 to 7:00 the next day", which conflicts with 7:00-23:30 on the load-in route map. Load-in and load-out may not be possible without prior application. Advance mailing of packages needs coordination with the events before and after, so consult the person in charge and send them with arrival specified for the day before the use date (guideline: up to 10 boxes, 180 cm or less in the sum of three sides and 30 kg or less).

Delivery vehicle rules

Vehicles allowed to enter are up to 3,000 mm high x 2,200 mm wide x 6,400 mm long, up to a 2-ton short truck (load capacity 2,000 kg). Loading and unloading at street level is not possible; the loading areas on B1F (2 spaces) are used. The loading area is free for the first 30 minutes after entry, then 250 yen per 30 minutes. Vehicles cannot be left standing; leave promptly when work is finished (the Operations & Preparation Q&A says to move in principle within 30 minutes). The freight elevator and loading area are common areas of the building, so do not obstruct other tenants or visitors. Parking cars, motorcycles and bicycles on the street is prohibited by the terms of use.

Parking

The hall has no dedicated parking lot; use the paid mechanical parking lots underground. Osaki Bright Core underground has 35 spaces (for sedan-type cars), with vehicle limits of 1.55 m high, 1.85 m wide, 5.0 m long and 1.9 t. Osaki Bright Tower underground has 51 spaces (for wagon-type cars), with limits of 2.05 m high, 1.95 m wide, 5.30 m long and 2.3 t. Neither can be reserved. From 7:00 to 23:30 the fee is 250 yen per 30 minutes (maximum 1,800 yen); from 23:30 to 7:00 the maximum is 500 yen and entry and exit are not possible. There is no parking discount. There are parking vouchers that can be settled when paying the balance; if you use them, notify the venue at least 2 weeks before the event. Bicycle parking is on the grounds around the outside of the building.

There are 3 waiting rooms. Waiting room 01 is 29㎡ (8.7 tsubo), waiting room 02 is 29㎡ (8.7 tsubo), and waiting room 03 is 25.2㎡ (7.6 tsubo). Waiting rooms 01 and 02 can be used as one.

Catering and outside food/drink

Eating and drinking is allowed in all areas. Open flames and cooking are not allowed. For boxed meals and the like, the venue can arrange several companies (pickup handling, trash disposal and consolidated billing are available), and no fee is charged when the user arranges directly. There is no designated-vendor system. When arranging directly, consult in advance about the load-in route and the like, and the people involved do a site inspection. The user disposes of or takes away boxed-meal trash. Trash up to a total of 540 L is disposed of free if sorted. A standing reception in the foyer is 5,500 yen per person (tax included) for food plus 2 hours of free-flow drinks.
