The Japanese town of Kitakyushu, in a 4-hour drive from Tokyo, is known for his flower garden Kawachi Fuji Garden's. One of the most striking sights of the place is Wisteria tunnel. The name comes from a plant whose branches cover the tunnel. This is Wisteria, although it has another name - Glycine.
