How to say "blockbuster" in Japanese

• ブロックバスター
  nounThe loanword, taken straight from English and covering the same sense — a hugely successful film. It is less common, however, and seldom the word you want: ヒット作 or 超大作 are safer choices.
• ヒット作ヒットさく
  nounThe 'hit' or 'bestseller' sense: a film, song, or book that is a big commercial success. Choose it when the point is a work's success rather than its scale or spectacle.
• 超大作ちょうたいさく
  nounThe 'spectacular production' sense: a tremendous, large-scale work. It stresses sheer scale and spectacle rather than commercial success, unlike ヒット作.

Choose 「ヒット作」 for the 'smash hit' sense — a film, song, or book that succeeds commercially — 超大作 for the 'spectacular, large-scale production' sense; 「ブロックバスター」, the direct loanword, is less common and seldom needed.
