Yakuza 4

You collect Memo’s as you progress through the story and interact with people, and also as well as exploring the city. Like the trophy describes, you can check your progress at anytime by accessing the Pause Menu with

As you’re wandering around Kamurocho, both on the streets as well as the rooftops, you’ll notice certain people at times will have a blue triangle on top of them. Talking to these people will unlock a Memo.

Once you've gotten your last Memo, you must go into the Memo Menu in order for the trophy to pop.

If you somehow missed a Memo, note the Memo's carry over to Premium New Games, so you can collect the ones you missed then.
