のはXの方だ

The pattern のはXの方だ is used to emphasize that a specific thing (X) is the one that stands out or is preferred among options. It often contrasts X with other possibilities and is used when you want to single out X as the main point or correct choice. In many cases, the front clause introduces the subject being contrasted (or the context), and の方だ marks the tailing noun phrase as the “the one” that fits the speaker’s judgement. Typical contexts include choosing between alternatives, highlighting what you consider the true/most appropriate thing, or correcting a mistaken assumption by pointing to the correct item. Note that X can be a noun phrase, and the overall sentence often ends with の方だ to make the assertion strong and definitive; it can sound slightly formal or emphatic. Example details often rely on a broader conversation about options, preferences, or evaluations.
