ものとするFormal rule: shall or is to

ものとする formally establishes an action, requirement, or procedure as a governing rule. In laws, contracts, policies, and official procedures, it often corresponds to “shall” or “is to.”

What the construction does

This construction does more than describe what usually happens. The provision itself establishes what is required. Its English translation should therefore preserve that rule-setting force with wording such as “shall,” “must,” or “is to,” depending on the document and legal context.

Positive and negative provisions

A positive form establishes a required action or procedure; a negative form establishes a prohibition.

しんせいしゃは、つうけたからとおないひつようしょるいていしゅつするものとする

The applicant shall submit the required documents within ten days of receiving notice.

Analyze

The provision identifies the responsible party, the deadline, and the required action.

ようしゃは、かんしゃきょなくりょうがいさないものとする

Users shall not remove materials from the premises without the administrator’s permission.

Analyze

The negative verb establishes prohibited conduct rather than merely predicting that users will not do it.

Make the rule unambiguous

Formal provisions commonly state who must act, what triggers the rule, what action is required, and any deadline or condition. Although Japanese can omit information understood from context, omitting the responsible party in an isolated rule may leave unclear who has the duty.

A procedure triggered by a condition

けいやくないようへんこうするあいは、そうほうしょめんごうするものとする

If the terms of the contract are changed, both parties shall agree to the change in writing.

Analyze

The condition activates a formally established procedure.

Rule, assumption, existing arrangement, or decision?

ものとする has identical wording when a document sets a working assumption or treats something as having a particular status. The difference is its job: the present point governs conduct or procedure, while the assumption use supplies a basis for analysis. By contrast, ことになっている reports a rule or arrangement that is already established, ていしゅつすること gives a concise instruction, and ことにする expresses a person’s or group’s decision.
