About 80 omoigawa-zakura cherry blossoms bloom every year along the embankment of the Omoigawa River, and the promenade along both sides creates a light pink cherry blossom tunnel. Omoigawa-zakura cherry blossoms came into existence due to a mutation and were discovered in Oyama City in 1954. The shape of these trees has a characteristic supple gracefulness to them. They are illuminated after dark as well, so visitors can enjoy the uniqueness of the omoigawa-zakura in the city both day and night.
