How to tell them apart
あとで treats the first action as a completed event and then places the second action somewhere after it, so it works even when the two are not back-to-back (日本へ行ったあとで病気になった). てから chains actions in order and stresses that the second thing happens once the first is done, often as an immediate next step or an ongoing state since that point (シャワーを浴びてから寝る). Swapping them sounds off when you need the gap or the since sense.
- あとで Use あとで when the second event simply happens sometime after the first, not necessarily right away.
- てから Use てから when the second action follows directly after finishing the first or marks a point something has continued since.
