• ショーJLPT N1approx.Common
  nounPrimarily 'show': a performance or entertainment presented to an audience. Its 'exhibition; fair' senses exist, but for a large-scale expo or exposition it is seldom the word you want.

For the event itself choose 博覧会, the general term for a large exhibition, or 「エキスポ」, the direct loanword for 'expo'; 「ショー」 means a show or performance and is rarely right for expositions.
