How to say "launch" in Japanese

  That company just put up a web page.
• オープニングCommon
  nounA loanword noun for the opening or start of an event or show; its 'launch' sense is secondary, so it is seldom the word you want for launching a business or product.
• 打ち上げるうちあげるCommon
  ichidan verb, transitive verbThe verb for launching something physically into the air, such as a rocket; it also means shooting something up or hitting a ball high, so it concerns upward flight, not starting a business.

  They shoot them off over the lake.
• 打ち上げうちあげCommon
