Based on an agricultural TV show, Daichi-kun Crisis is facing serious issues after a witch called Jaren creates a series of volcanoes, and a black path, which in turn unleashes monsters on to the land.
The player takes control of the titular cow farmer Daichi-kun. The aim of the game is to build up a successful arable farm by planting and harvesting crops, then selling them for money to buy farming supplies, while clearing monsters and the ash they deposit to protect the crops. Success of the farm is dependent on keeping the Geiger No Machine running.
Gameplay involves using various farming tools to clear land, plant and harvest crops, and manage resources. The player must also navigate the island's geography, avoiding obstacles and managing resources carefully in order to achieve success.
