To get the fishing pole
Alright, now. I know many of you don't need to know this, but this is for some newbies. I didn't know this question, but then I solved it.
You get the fishing pole from Zach, (I think thats his name), and he is the shipping guy. He shares his house with Won. They live on a cottage right next to Kai's house on the beach. When you go over to his house one day, he will say, "Hmm, what do I do with this." You then acquire the fishing pole. I am not positive if you need to befriend, but you probably should anyways. Just give him a fruit or vegtable every now and then when he comes to pick up your shipment, which is at 5 p.m.
How long this takes, I don't know. I got my fishing pole in Winter, Year 1, but I'm slow in these things. Hope this helped!
