While Uonuma City in Niigata Prefecture is often associated with snowy winters and world-famous rice, summer reveals a quieter side filled with lush greenery, mountain breezes, and fresh seasonal produce. One of the best ways to enjoy this summertime charm is by visiting Marie's Farm.

From July to mid-September, Marie's Farm opens its gates for an all-you-can-eat blueberry picking experience. With around 1,000 trees and 30 different blueberry varieties spread across a wide, well-maintained field, visitors can roam freely and sample fruit straight from the bush. There's no time limit, so you can take your time tasting your way through the orchard while surrounded by nature.

What makes these blueberries stand out from others is the water used in the growing process. Uonuma's soft, mineral-light water (with a hardness of just 16 mg/L) plays a key role in producing berries that are not only sweet and juicy, but also remarkably clean in flavor. Different varieties ripen at different times, which means that repeat visits throughout the season offer something new each time.

The farm is also designed for comfort. The paths are covered in plastic sheeting to keep shoes clean, and strollers are welcome. Trees are kept low, making it easy for children to reach the berries, so it's perfect for a relaxed family outing. Regardless of whether you're a serious fruit lover or just looking for a peaceful summer activity, this is a great way to enjoy the natural beauty of Niigata while cooling off in the countryside.
