📝 Usage Notes

to assume; to suppose ~

📖 How to use it

This pattern expresses that something is regarded or assumed to be the case, often as a basis for action or discussion.

Attaches to Attach to the dictionary (plain) form of a verb or adjective, or to a noun + だ (which becomes である before ものとして). For な-adjectives, use なものとして or であるものとして.

This pattern is used when you take a certain situation or claim as a given assumption, even if it may not be fully true or verified. It often appears in formal or written contexts, such as in contracts, policies, or logical arguments. The nuance is that you are setting a premise: 'let's assume X' or 'we proceed on the basis that X.' For example, a company might say '採用するものとして進める' meaning 'we proceed on the assumption that we will hire him.' It can also sound like you are taking responsibility for a decision or interpretation, as in 'あなたが同意したものとして扱います' (we will treat it as if you agreed).

この書類に署名したものとして、契約が成立します。
Kono shorui ni shomei shita mono toshite, keiyaku ga seiritsu shimasu.
The contract is considered established on the assumption that you have signed this document.
彼は無実であるものとして、調査を続けるべきだ。
Kare wa mujitsu de aru mono toshite, chousa o tsuzukeru beki da.
We should continue the investigation on the assumption that he is innocent.
この計画は成功するものとして、予算を立てましょう。
Kono keikaku wa seikou suru mono toshite, yosan o tatemashou.
Let's set the budget assuming this plan will succeed.
Not とする (to assume/suppose) とする is more direct and often used for setting a hypothesis or making a decision, while ものとして emphasizes a state or condition that is taken as a given. For example, 彼が犯人だとする means 'suppose he is the culprit,' while 彼が犯人であるものとして means 'on the assumption that he is the culprit,' focusing on treating it as a basis.
Register This is a formal, written expression, common in legal, business, and academic contexts; it sounds unnatural in casual conversation.
