What it means
そのために links a previously stated cause or situation to its result. It means “for that reason,” “because of that,” or “as a result,” and is commonly used at the beginning of a new sentence or clause. It is especially useful in explanatory and somewhat formal writing, reports, and presentations.
Usage note
そのために can also mean “for that purpose” or “in order to do that.” The intended meaning is determined by context: a preceding cause leads to the result in the “for that reason” use, while a goal or intended action leads to the purpose-related use.
