Geographical/topographical features

This hilly forest, while located adjacent to the urban district of Shiraoi town, has a primitive and ancient air. Bougakudai Observation Platform offering panoramic views of mountains, including Mt. Tarumae, Mt. Horohoro and Mt. Shiraoi, and magnificent vistas of Pacific Ocean and its coastline
Historical/cultural features
Before its designation as a Recreation Forest in 1976, Poroto forest served as a sapling nursery, where trees were grown for planting on the mountains. Among the trees cultivated here were todomatsu, Todo fir (Abies sachalinensis). In 2020, the Symbolic Space for Ethnic Harmony (National Ainu Museum and National Park for Ethnic ) is due to open in an adjacent site, so this area is expected to become a center for disseminating Ainu history and culture.
Climate, flora and fauna
The tree species planted in the Recreation Forest include Todo fir; karamatsu, Japanese larch (Larix kaempferi); and ezomatsu, Yezo spruce (Picea jezoensis). Growing naturally among them are mizunara, Japanese oak mizu-nara (Quercus crispula Blume); harunire, Japanese elm (Ulmus davidiana var. japonica); yachidamo, Manchurian ash (Fraxinus mandshurica var. japonica); sen (harigiri) (Kalopanax pictus); and kuri, chestnut (Castanea crenata). Large trees in excess of 100 cm in diameter can be seen here and there in the forest. Poroto Recreation Forest is also home to mizubasho, Asian skunk cabbage (Lysichiton camtschatcensis), along with other herbaceous wetland plants. Among the animals living in the forest are ezoshika, Yezo sika deer (Cervus nippon yesoensis); kitakitsune, Ezo red fox (Vulpes vulpes schrencki); ezomomonga, Russian flying squirrel (Pteromys volans orii); and ezorisu, Hokkaido squirrel (Sciurus vulgaris orientis). In addition, it provides a habitat for around 80 bird species, including akagera, great spotted woodpecker (Dendrocopos major); oruri, blue-and-white flycatcher (Cyanoptila cyanomelana); and kurotsugumi, Japanese thrush (Turdus cardis).
Poroto Recreation Forest has a walking trail (cycle track) of 6 km long around the Lake Poroto, which enables visitors to enjoy the seasonal change of nature. Other footpaths lead to an observation tower with a view of Mount Tarumae, and to Momiji-daira, where visitors can soak up the spectacular sight of red and golden leaves in autumn.
The forest is equipped with all facilities to help visitors relax and unwind, including a campsite, cabins, a cookhouse, and toilets. In winter, Lake Poroto freezes over, offering the chance to enjoy ice skating and fishing for wakasagi, wakasagi smelt (Hypomesus nipponensis).
