500 koinobori swimming above rapeseed fields with the Nasu mountains behind
An annual spring event at Nasu Heartful Farm in Tochigi. Over 500 colorful koinobori are raised above a vast 4-hectare field of yellow rapeseed flowers. The snow-capped Nasu mountains form a stunning backdrop, creating a breathtaking contrast of yellow blossoms, colorful streamers, and the residual snow. Children can freely walk through the maze-like flower field while koinobori swim overhead, making it a highly photogenic destination. It has become a signature spring sight in the Nasu Highlands and a popular family destination during Golden Week.
