を通じて・を通して

を通じて／を通して are used to express that something happens or is achieved through a channel, method, or period. They emphasize the process, medium, or means by which something occurs, rather than the result itself. を通じて often sounds a bit more formal or official, especially in written or institutional contexts, while を通して is common in everyday speech. This grammar can refer to a physical route, a media or channel (such as letters, media, or organizations), or a broader span like a period or experience that enables something to happen. It can also imply ongoing or repeated actions during the channel. When the focus is the means or medium, use these phrases to show that effect comes through that conduit.
