具体的に言えば

You usually drop this at the start of a sentence. It follows a general statement you just made. For example, you might say, 'I want to eat healthy.' Then you follow up with, 具体的に言えば、毎日サラダを食べます (Specifically speaking, I will eat salad every day). It acts as a logical connector. It prepares the listener's brain for data, numbers, or specific names. It is very versatile and works in almost any setting.

This is a lifesaver in business meetings. If a project feels too vague, use it to pin down tasks. It is also great when giving directions or explaining a complex hobby. Use it when you see a confused look on your friend's face. It shows you are being helpful and clear. Use it when you want to prove a point with evidence. It makes you sound organized and thoughtful.

Don't use it if you are just going to repeat yourself. If your 'specific' point is just as vague as the first one, it feels redundant. Also, avoid using it in very emotional, heat-of-the-moment arguments. It can sound a bit too clinical or cold when someone is crying. It is a logical tool, not a poetic one. Don't use it if you are being intentionally mysterious or vague. It ruins the surprise!

Japanese communication often relies on 'reading the air' or kuuki wo yomu. This means people are sometimes intentionally indirect to avoid conflict. However, in modern Japan, especially in tech and business, clarity is becoming king. 具体的に言えば is the tool used to cut through the fog of politeness. It allows for precision without being rude or aggressive. It shows a respect for the listener's time by getting straight to the point.

You will often hear 具体的には (Gutaiteki ni wa), which is a bit shorter. In casual settings, you might hear 詳しく言うと (Kuwashiku iu to), meaning 'to say it in more detail.' If you want to be very formal, you could use 具体的に申し上げますと (Gutaiteki ni moushiagemasu to). All of these serve the same purpose of narrowing the focus. Choose the one that fits your current 'vibe' and social standing.
