Bird-Watching Guide: June’s birds in Oyama’s Ramsar Wetlands, Yamagata prefecture




Birdwatching in Japan offers the chance to observe an extraordinary diversity of resident, migratory and endemic species, and Tsuruoka is one of the best places in northern Japan to experience it. Nestled between the Ramsar-listed wetlands of Kamiike and Shimoike and the forested slopes of Mt. Takadate, the Oyama area provides excellent birdwatching opportunities throughout the year. Kamiike and Shimoike were designated Ramsar Wetlands of International Importance thanks to their crucial role as stopover and wintering grounds for migratory waterfowl along the East Asian–Australasian Flyway.
From elegant Mandarin Ducks and Ospreys to colourful Japanese Paradise Flycatchers and Ruddy Kingfishers, more than 40 species can be observed in and around these rich natural habitats.
Within a radius of only a few kilometres, birdwatchers can explore wetlands, reed beds, satoyama woodland, coastal forest and low mountain habitats.
The area is also home to Oura Aichokan, Tsuruoka’s Bird Lover Center, where visitors can learn more about local wildlife before heading out into the field. Early morning is the best time to explore the lakes and surrounding forests, particularly during the migration season.
Oyama can be reached by train via the JR Uetsu Line (Uzen Oyama Station) or by bus bound for Yunohama Onsen via Zenpoji. The nearest bus stop to Hotoria and Oura Aichokan is Oyamaumamachi.
