Kawa no Nushi Tsuri

Kawa no Nushi Tsuri is a fishing RPG for the NES/Famicom where you play as a young fisherman in a river valley town. After your sister falls ill, you quest through different river sections like Keiryuu, Jouryuu, and Chuuryuu to find the legendary River King (Nushi) fish. Gameplay mixes exploration with top-down map navigation, bait selection, and timed fishing mechanics. Battles are timing-based with a white cursor you aim at enemy weak points by pressing A; you can also eat or escape. Progress by catching fish to sell for better rods, lines, and equipment. Characters include your sister (sick child), mother, and yourself as the protagonist. It stands out for combining light RPG elements like random wildlife encounters and password saves with realistic pastoral fishing on Famicom hardware.
