From around early June to mid-June each year, Nagaoka's Echigo Hillside Park is home to a rose festival, with blooms in a variety of different colors and from different regions of the world. Along with the visual treat that the roses present, there are also a range of rose-themed items for sale, including rose-flavored soft serve ice cream at the on-site Rose Cafe.
Do note that since the festival dates are reliant on when the roses bloom, there can be some fluctuation from year to year. Please visit the official website for further information closer to June.
Adult admission to the park is priced at 450 yen. Children who are junior high school-aged and younger receive free admission.
