The event hall is suitable for various types of events such as trade fairs, industrial exhibitions, festivals and concerts. (http://www.oki-conven.jp/english/event.html)
I wonder if the term 'event hall' commonly used in English for
such a thing as above.
If not, is there any other term for it?

Thank you.

Yep. Very common. Usually distinguished from a theater by it's purpose (generally not plays or performances, but lectures, presentations and demonstrations). Event halls are very large rooms. The layout has flat, rather than tiered, seating arrangements.

Thank you very much for the valuable information.
