Koshimizu Genshoen is a precious natural environment located within the Abashiri Quasi-National Park and is officially registered as a Hokkaido Heritage site. This area has undergone significant changes in its vegetation due to past grazing and the influence of steam locomotives; however, intensive efforts are currently underway to restore its natural ecosystem. From early summer to autumn, you can witness a stunning display of wild flowers such as Ezo Lilies, Rosa rugosa (beach roses), and Eriocaulon (Ezo Kisuge) amidst the raw, beautiful nature of the Okhotsk region.
The history of this natural garden is deeply tied to the landscape's evolution. Until the 1960s, the area was shaped by grazing and the sparks from passing steam locomotives. By the 1980s, as grazing and steam locomotive use ceased, the landscape faced a challenge where overgrown grasses began to overtake the once-beautiful floral displays. To address this, a research team from Hokkaido University conducted surveys in 1990, leading to the introduction of a traditional management method called "Hi-ire" (controlled burning) starting in 1993. Even today, this cyclical controlled burning is used to maintain the environment necessary for wild flowers to thrive.

The greatest draw is the seasonal transformation of the wild flowers. In early summer, the landscape is painted with vibrant orange Ezo Lilies and the delicate white Eriocaulon. Beyond the flora, the garden is a known stop for migratory birds, allowing visitors to feel the rhythmic cycles of nature. Located near the Sea of Okhotsk, the area offers a sense of the vast, grand scale typical of Hokkaido's wilderness.
The best time to visit depends on what you wish to see. From May to September, the scenery shifts alongside the plant growth. The period from early summer to summer is particularly ideal for observing colorful blooms like the Ezo Lily. You can also visit during the winter to observe bird patterns. For the best experience, visiting during bright daylight hours is recommended to fully appreciate the vivid colors of the flowers.

Visitors can experience the natural cycle of the earth firsthand. For instance, in early May, the "Hi-ire" (controlled burning) process may occur—a vital cultural and ecological process to maintain the vegetation. This involves teams carefully creating firebreaks to protect the environment. Other popular activities include bird watching and nature photography, using the seasonal wildflowers as a stunning backdrop.
The surrounding area is filled with spots to enjoy the Okhotsk Sea's natural beauty. Nearby, you can visit Tofutsu Lake, famous for its beautiful sunsets, or the Koshimizu Lily Park to enjoy seasonal scenery. There are also local eateries serving seasonal ingredients and accommodation options like Koshimizu Onsen, allowing you to combine a nature walk with local culture and cuisine.

Protecting the environment is crucial during your visit. While there are no fees for entering the garden, please note that nearby facilities and restaurants may require cash or credit cards. English signage is limited, so we recommend checking information in advance. Photography of the landscape is encouraged, but please be mindful not to damage any plants. As this is a protected natural area, some paths may be unpaved; please wear comfortable walking shoes and stay on the designated paths to protect the delicate ecosystem.
