When to use it

Use ～を前提に when stating the assumption or precondition that some action, plan, or discussion is built on. It is common in business writing and meetings to make explicit what has been taken for granted — budgets, deadlines, approvals, contract terms. The fuller ～を前提として is slightly stiffer and appears in contracts and formal reports.

Formation

  • Noun: 名詞 + を前提に／を前提として／を前提にして (例:値上げを前提に)

  • い-adjective: plain form + ことを前提に (例:納期が短いことを前提に)
  • な-adjective: 〜である + ことを前提に (例:実現可能であることを前提に)
