During the heart of the Edo era, the sea surrounding the nearby Edo Bay had a larger abundance of fish and shellfish, much more than the current day and age. Villages built up a thriving fishing lifestyle and market, catching a variety of delicious fish like horse mackerel, shrimp, clams.

Step back three hundred years ago, and experience what it was like to work in a coastal village in Japan. Players are fishermen trying to earn a living in one of nature's best providers: the sea. Over the course of five rounds, you'll need to bring back enough fish, and use your connections to help your fishing livelihood survive. Make wise choices to increase the number of actions you can take, and borrow money carefully to help further your finances.

In Isaribi, players have a limited number of action points, and on their turn they perform actions such as get fish, sell the fish, upgrade their fishing ship or net, and gain more AP. Whoever is able to gain the most wealth wins.
