After unlocking the mountain through using two tablets, you'll need to start gathering tulips, stone, and wood. The house north of Naomi and Sally's needs all of these, and 1,500g, to repair. The day after, you should be able to get a fishing pole from the new tenant in the form of Cyril, wandering upon your farm starving. Give him something to eat and he'll return your kindness with the pole.
