Murata in Ariake

There is also a parking lot on the Big Site site. Temporary parking lot is available by event. I remember that there were 5 to 6 locations around the big site and 2 to 3 locations on the site at the time of a big event. I think that the price of the parking lot was around 1500 yen ~ 2000 yen a day.

Is it better to stay a few stations away from 8 o'clock in the morning?

Differs depending on the event. You must check which to need the reservation for the event that you want to go is. (Ex. Website) (Japanese translation) Whether reservation is necessary or not depends on the event to be held. However, for common facilities such as entrance hall and restaurant, anyone can use it within business hours. As the East and West Hall are used at the event, please contact the organizer of the event in advance. (It is generally stated on the website of the event.)

There is a food court on the ground floor, where you can drink after the event. But closing is early

Although it is expensive, I think it is safe because it is large in space.

There are many exhibitions.

If you get off at Yurikamome's International Exhibition Center Main Gate, you will be in front

I don't think so.
