Wakka Wild Flower Garden is located in Sakaeura near Tokoro in Kitami, Hokkaido. The garden is part of Abashiri National Park and is situated near the Okhotsk Sea coast and on the shore of Saroma Lake, one of Japan's three biggest lakes. As a natural treasury, it has been designated as a site of Hokkaido Heritage.

'Wakka' in the language of the native Ainu people means 'drinking water' or 'springwater'. On the long sandbar dividing Saroma Lake and the Okhotsk Sea, there is a spring called Wakka Flower Holy Water. The name Wakka here refers to the rich supply of water in the area. The sandbar is 200~700m wide and about 20km long. It is the biggest area of seaside grassland in Japan.

Varying ecosystems have formed within the forest, grassland, dunes and marsh. More than 300 kinds of plants and flowers grow here including species from outside. The area is also a natural habitat for various wild birds.

Wakka Wild Flower Garden is also known as Ryugu Highway and features vivid natural scenery.
