Yakuza 4 Remastered

All you have to do is cast a fishing rod 5 times at the dock (I did 3 in a row then bought more bait from the fisherman and then did 2 more, catching a Tuna, 2 oil drums, a briefcase, and missing once, meaning you don't have to catch something for it to count, however I did not try to exit the minigame to save time before failing it).
Then I went to the golf course (only available during the day, I did this in Part 5) and chose to practice (it's free, I chose hole 1 and 2) doing a single stroke then choosing to Quit when the menu popped up. I did this a total of 5 times and the achievement popped.

Save game first if all you’re doing is going for achievement, so you can reload the save after it pops. Use taxi during DAYLIGHT hours in order to play golf.

This is pretty self explanatory, but I wanted to add that you don’t actually have to play 5 entire rounds of golf. I simply played one hole then backed out of the mini game, paid entry, entered tournament and did it again. After the achievement popped, i reloaded my save file to get my money back.

I was not able to play Golf until Part 3 with Tanimura because it has to be daytime to do it, and unless I missed it, this was the first opportunity that I was aware of.

For Fishing, simply chose Docks from Taxi and fish 5x. Buy bait from dude at the docks. Just to be sure, i backed out each time and then chose to fish again to make sure it counted as going fishing 5x. I wasn’t sure that simply catching 5 fish in one fishing session would do it, nor do I know if you have to actually catch a fish for the fishing session to count. What I do know is that backing out each time after catching one fish worked.
