About

A circus troupe comes to Yomogi Town, a rural town in Japan situated between mountains and the ocean. As the son of the circus ringmaster, enjoy a special summer filled with adventures!

All of Yomogi Town and the nature surrounding it are an open world where you can enjoy summer to its fullest. Immerse yourself in nostalgic scenery filled with towering clouds, beautiful sunsets, and the sound of cicadas.

Summer days are always filled with activities like fishing at the river or catching rare bugs in a field. Help the circus succeed and interact with the townspeople if you’d like. Enjoy a night at the summer festival, dancing and watching fireworks. There’s even a train so you can visit a neighboring town.

Your own special summer vacation filled with unique experiences awaits you!
