1. Sekai - Yachi alpine meadows
A series of alpine meadows on the foothill of Mt. Kurikomayama in western Miyagi. These meadows are devided into several areas on the different histories of each. They are very important for realisations of the histories of our land and climate based on the pollens in their peat.
2. Lakes Izunuma and Uchinuma
Two lakes on the Sendai Lowlands. They are shallow and rich in water plants. It is very short time to be frozen up in winter. These factors results in a highest number of larger waterbirds (swans and geese) wintering in the lakes in our country -- Most individuals of Anser albifrons in Japan spend the winter here. Two lakes are protected as Prefecture Nature Conservation Area of Miyagi and are designated as Ramsar site.
3. Lake Kabukurinuma
A lowland lake having very wilderness landscape lying c.10km south of Lakes Izunuma and Uchinuma. It plays roles of water storage for illigating rice fields around and of flood mitigation. Recently another importance as habitat of wild birds including waterbirds draw the attention of peoples. It is current task to manage the lake having a high capacity of water storage without ecological degradation.
4. Onoda Lakes
