その為(ため)にFor that reason, Because of that, To that end

The two Japanese phrases, すると and そのため(に), are used in different contexts. すると is used to indicate a natural or logical outcome or consequence of a certain action, it is often translated as 'and then', 'if', or 'when'. On the other hand, そのため(に) is commonly used to express the cause or reason for a certain outcome, it is often translated as 'for that reason', 'because of that' or 'hence'.

そのため(に) and それで both show cause and effect. それで is casual and used in everyday speech: 道が混んでた。それで遅れた ('The road was crowded, so I was late.'). そのため is more formal and can also express purpose, e.g. 健康のため、運動している 'I'm exercising for my health.').

These share the same core construction, using ため(に) to express 'in order to (A)' or 'due to (A)'. ため(に) is used within a sentence after a noun, verb, or adjective phrase. そのため is used at the beginning of a sentence to mean 'for that reason' or 'due to that', referring back to what was just said.

そのため(に) can be seen as a more specific version of ために. ために follows a noun, verb, or adjective phrase to express purpose or reason. そのため(に) appears at the beginning of a sentence and means 'due to that' or 'in order to do that', referring back to what was previously said.

Both expressions relate to cause and effect, but in opposite directions: なぜなら〜から gives the reason for something previously stated, while そのため(に) introduces the result of a prior situation. Additionally, そのために can also express purpose, a meaning なぜなら〜から does not carry.

Both せいで and そのため(に) show cause and effect, but せいで follows a word or phrase and implies a negative result or blame, e.g. 台風のせいで試合が中止になった ('The game was canceled because of the typhoon'), while そのため(に) is used at the beginning of the sentence and neutrally shows a logical result of whatever was previously stated. そのため(に) can also express 'for the purpose of (A)', which is a nuance せいで cannot have.

These expressions are similar in that both are used at the beginning of a sentence to express the effect of a cause mentioned just previously. そのため(に) implies a direct, logical cause, like the English 'due to that', while その結果 focuses on the ultimate condition or situation brought about by the cause, like 'as a result of that'. そのため(に) can also express 'for the purpose of (A)', which is a nuance せいで cannot have.

Both are typically used at the beginning of a sentence to show what follows from a certain cause or situation. そのため(に) more clearly states the relation and can mean either 'due to that' or 'for that purpose', while そこで is less clear about the relationship between the previous thought and what follows, similar to the English 'as such' or 'in light of that'.

Both express cause and effect, but with different tone and usage. おかげで implies a positive result and gratitude, e.g. 先生のおかげで合格できた ('Thanks to my teacher, I passed.') そのため(に) is neutral, objective, and often appears at the start of a sentence. It can also mean 'for that purpose'.

Both introduce reasons, but そのため(に) shows a direct consequence or effect from what was previously stated, while という理由で introduces a reason more abstractly and with a greater degree of formality. They also differ in how they connect the reason to the consequence, with そのため(に) always appearing at the beginning of a sentence, and という理由で being able to appear either at the beginning or in the middle of a sentence.
