For both the hall and the conference rooms, bookings are made for time that includes setup and teardown. The standard usage time is 9:00-21:00, and 8:00-9:00 and 21:00-22:00 incur an after-hours extension fee, technical management fee and personnel costs. The hall's basic venue fee is 1,130,000 yen (9:00-21:00, excluding tax). The layout for both the hall and the conference rooms is finalized by 14 days before the use date (excluding Saturdays, Sundays and holidays).

Load-in and load-out

Loading in and out is done from the loading dock on B2F of Nihonbashi Muromachi Mitsui Tower, and goods are taken up to 3F by the loading/unloading elevator (F-1, load capacity 2,000 kg, B2F to 3F). The loading dock reception (in-house logistics center) is open weekdays 7:00-19:00 and Saturdays, Sundays and holidays 7:00-17:00. Outside these hours, loading in can start without any procedure. The "Loading/Unloading Registration" must be submitted to Muromachi Mitsui Hall & Conference by 10 days before the use date (excluding Saturdays, Sundays and holidays), and the in-house logistics center issues a permit. Only air carts with stoppers may be used as hand carts; up to 3 are free at the hall, and beyond that it is 100 yen per 30 minutes (tax included) at the in-house logistics center. When carrying goods by any means other than an air cart, protective covering (curing) is required inside the elevator and along the loading route.

Delivery vehicle rules

Loading/unloading vehicles must obtain a permit in advance, display it on the windshield, and enter the B2F loading dock from the entrance on the Nichigin-dori side (one-way). Vehicle limits are height 2,980 mm, length 6,600 mm and width 2,400 mm. The loading dock fee is 250 yen per 30 minutes (tax included), and 250 yen for each 30 minutes after that. With a permit, the first 20 minutes are waived. The number of vehicles that can be accepted at the same time is limited, and you may be asked to enter one vehicle at a time in turns. Fees to the in-house logistics center apply when 3 or more vehicles load in or out, for work outside the logistics center's hours, when the loading/unloading elevator is used continuously for 1 hour or more, and the like. The Terms of Service prohibit parking vehicles such as cars on the street. (Source: Loading and Unloading Guide as of August 5, 2026, Terms of Service)
