Meaning
Assuming that / treating … as / on the premise that → something is handled as an established fact, rule, or condition, whether or not it is actually true
Formation
Clause (plain form) + ものとして + Clause
Noun + として + 扱う／考える／判断する
※ same logical use when explicitly stating “treat as”
Explanation
ものとして is used when the speaker sets an assumption or premise, and then acts, decides, or reasons based on that assumption.
The key idea is:
“Even if it’s not actually true, we will treat it as true for the purpose of judgment or discussion.”
Important nuances:
The assumption is intentional
The sentence proceeds as if that condition already holds
Often used for:
rules
planning
legal or administrative reasoning
Tone is formal, logical, and objective
This grammar is very common in:
regulations
contracts
academic writing
hypothetical or procedural explanations
