Geographical/topographical features
Lake Eniwa, nestled in a Recreation Forest, is an artificial flood control lake created by damming the Izari River that flows through Eniwa City. The name "Izari" is derived from "ichan," which means a salmon and trout spawning ground in the language of the Ainu people. The river basin has supported humans and a diverse array of other organisms since time immemorial.
The Eniwa Valley is upstream from Lake Eniwa, while Midori no Furusato Forest Park and Sakura Park lie to the south and west (downstream) of the lake, respectively. In the Eniwa Valley, a tributary of the Izari River, the Rarumanai River, flows with many waterfalls along its course. The area has been designated by Eniwa City as Rarumanai Nature Park, a scenic spot boasting beautiful autumn leaves.
Historical/cultural features
[Legend of Yoshitsune's hidden treasure] According to local legend, famous samurai Minamoto no Yoshitsune, who was believed to have committed suicide at Hiraizumi, actually fled to Ezo (today's Hokkaido). He is said to have buried his treasure in the Kumanosawa marshland in Eniwa and to have left behind a treasure map containing notes and a golden treasure inventory bearing his family crest, the "Sasarindo," which depicts bamboo grass and gentian blossoms.
[Banjiri forest tramline] The tramline was constructed in 1927 to enable a power plant to be built for Oji Paper Co., Ltd., and was purchased by the Eniwa Forest Management Office in 1931. The tramline was then extended to the upper reaches of the Izari River and was used to transport timber for post-war reconstruction until its closure in 1955.
[Eniwa Mine] Gold and silver were mined at the Eniwa Mine located in the vicinity of the upper Izari River. Around 1940, a mining town developed with public facilities, including an elementary school and a post office. The mining town disappeared when the mine closed in 1943, and only the ruins of a few buildings―such as a crematory―remain today.
Climate, flora and fauna
The Recreation Forest is a mixed forest of broad-leaved trees such as Yachidamo (Fraxinus mandshurica var. japonica), Mizunara (Japanese oak mizu-nara (Quercus crispula Blume)) and Ezoitaya (painted maple (Acer mono Maxim.)) and conifers, including Ezomatsu (Yezo spruce (Picea jezoensis)) and Todomatsu (Todo fir (Abies sachalinensis)). It provides a habitat for a variety of forest birds, including Kumagera (black woodpecker (Dryocopus martius)), which has been designated a natural monument, migratory summer birds such as Kibitaki (narcissus flycatcher (Ficedula narcissina)) and Ezomushikui (Sakhalin leaf warbler (Phylloscopus borealoides)) and resident birds such as Higara (coal tit (Periparus ater insularis)) and Hashibutogara (marsh tit (Poecile palustris hensoni)).
The Eniwa Valley lies along the Rarumanai River, a tributary of the Izari River, and it can be reached by driving about 18 km along the Prefectural Road Eniwadake-Koen Line from the Eniwa city area going in the direction of Lake Shikotsu. The valley has three impressive and very different waterfalls: graceful Hakusen Falls, which are 15 m high and 18 m wide, and which resemble an open white fan; powerful Rarumanai Falls, which gushes down between giant trees; and Sandan Falls, where the rushing white water falls down, dramatically striking three levels of rock through the Eniwa Valley.
The Lake Eniwa Jiyuhiroba / Sakura Park and the Midori-no-Furusato Forest Park can be found along the way to these waterfalls. The Lake Eniwa Jiyuhiroba / Sakura Park is spotted with pergolas and flowerbeds, and Sakura Park sports beautiful spring cherry blossoms and colorful autumn leaves. Visitors to the Midori no Furusato Forest Park can get in touch with the abundant natural beauty, observe animals and plants and participate in educational activities concerning the forest environment.
