How to unlock the Substory Completionist achievement in Yakuza 3 - Definitive Guide
Sub stories are side missions found around Ryukyu and Kamurocho. You'll net ten, thirty, maybe fifty missions easily. However, the rest will take some dedication. As most of you know, some sub stories were cut from the North American version. Also, some of these sub stories are missable (google it). I'm sure you know missable means no trophy, so here are the missable sub stories....
*VERY MINOR SPOILERS*
Chapter 4: A Trip Before Marriage: This one was actually CUT from the game, so take some time to relax and forget about this one.
Chapter 4: Love Letter In A Bottle: When you get a chance in chapter 4, head to the beach out front of Sunshine Orphanage. You'll see what looks like a piece of trash floating near the fishing rod. Pick up the bottle and the quest begins. Piece of cake. EDIT: Okay, so apparently this shows up again in chapter 10. If you missed it in chapter 4, keep an eye out.
Chapter 6: Dotting the Eye: Dotting the eye should be done once you arrive in Kamurocho with Rikiya. After doing a few activities with Rikiya, he'll mention finishing his viper tattoo. To initiate it, head to the Divine Dragon tattoo parlor in Pink Ally.
Chapter 6: Girl From Back Home: This one starts when you're with Rikiya a second time, after arriving in Kamurocho. At one point, you'll drop him off at New Serena and eventually go out with him again. To initate it, head to Asia, the stripclub.
Chapter 12: The Couple Who Wouldn't Learn: This mission has also been cut from the NA version.
Don't forget to do these stories. If not, you'll be hitting yourself later on. As for the rest of the stories, a lot of them are mundane, boring tasks. Every once in a while you'll come across a unique sub story, like acting in a movie or a batting challenge, but most of the time they consist of fighting a set of enemies. Keep in mind that some sub stories are only activated when you do a certain act many times or something along the lines of that. For example, if you score 1200 points in the batting cages, you'll get a new sub story. I know it's cruel for them to hide missions like that, but whaddaya gunna do, eh?

Amon has an absurd amount of health, about 6 bars. Also in the first phase he fights with two Jewish swords, and then switches to pistols. After passing all the tests in IF7 you will gain the ability to block attacks with weapons during the HEAT mod, which makes the battle much easier. Also, don’t forget about counterattacking from a block in HEAT mode, using a triangle.
