A circus troupe comes to Yomogi Town, a nature-rich countryside town in Japan situated between mountains and the ocean. As the son of the circus ringmaster, enjoy a special summer filled with whimsical action and adventure!

The Acorn Shooter is super handy! Stun bugs with well-aimed shots and add them to your bug collection. Now compatible with Steam Deck’s gyro controls!

The entirety of Yomogi Town and the areas surrounding it are an open world for you to explore with utmost freedom. Immerse yourself in nostalgic scenery filled with towering clouds, beautiful sunsets, cicada hums, and the warm glow of lights from homes at night.

You can chill in the shopping district, listen to live music in the afternoon, or go on a wild and exciting adventure. It's all up to you.

Feel like climbing up a tall, steep cliff? Or hopping from one rooftop to the next? Maybe look for a hidden gem at a remote spot? No problem! Even if you drop from a very high place, you'll be perfectly fine because you're the protagonist of this game.

You can spend time in an open field, quietly admiring the little flowers.

See all the bugs you've caught by clicking on them through the menu. You can observe them closely by looking at them in your bug collecting kit. What a beautiful butterfly!

Go fishing at a river or the sea! Donate rare bugs and fish to the museum for their exhibits! Or have the fish you caught cooked into a delicious dish! Join the local detective agency, raise a wild pig, dig up fossils, ride a train, earn money... Record your daily activities in your own fun picture diary!

During the summer festival, fireworks and the Bon Festival dance liven up the night. You decide where you take in the sights. You can even help run the Fireworks Show!

And you'll be directing the performance of the circus troupe in the latter half of your summer vacation. What a huge responsibility! Are you up for it?

Make your own, unforgettable memories during your summer vacation filled with unique experiences!

This is the latest work by Kaz Ayabe of Millennium Kitchen, creator of several games themed around summer vacation and childhood nostalgia. Natsu-Mon: 20th Century Summer Kid comes to Steam.
