Japan’s Wisteria Festival
Ashikaga Flower Park in Japan's Tochigi prefecture, just 2 hours from Tokyo Station by train, is the host of the festival, and boasts over 350 wisteria trees that fill the park with dazzling colours year after year. Visitors can also walk through an 80 metre-long tunnel covered by unique white wisteria flowers. The wisteria floribunda tree is native to Japan, and some of the trees in Ashikaga are more than 150 years old, making them a landmark of Japanese natural heritage.
The Great Wisteria Festival of 2017 is set to start on April 15, and will last until late May. Ashikaga Flower Park was previously listed as one of CNN's "dream destinations for 2014," with one travel writer remarking that the wisteria trees looked "nearly identical to Avatar's spiritual Tree of Souls." If you can't afford inter-dimensional travel, then a trip to Tochigi just might do the trick.
