Formation
Verb (plain form) + とあれば
Noun + とあれば
Explanation
とあれば is used to express a strong or decisive condition.
It means that if a certain condition is met, then a natural, often strong reaction, decision, or action will follow.
Compared to ～ば / ～なら, とあれば emphasizes that the condition is important or compelling, often enough to justify a change in behavior, attitude, or decision.
This grammar is mainly used in formal or written Japanese, but it can also appear in serious spoken contexts.
