Otsu Kosigan Nagisa Park is a beautiful facility located along the shores of Lake Biwa in Otsu City, Shiga Prefecture, designed to bring people closer to the water and greenery. The park spans a vast area from Hama-otsu to the Omi Dai Bridge, characterized by its tranquil lake views and lush, well-maintained vegetation. Despite its proximity to the urban center, the park offers an expansive, open landscape that allows visitors to feel deeply connected to nature.
The area has been developed as a place of relaxation for both locals and visitors while preserving the stunning scenery of Lake Biwa. The landscape is part of a region with historical significance, including connections to the "Awazu no Seiran" (clear breeze at Awazu), one of the scenic views of Omi Hakkei. This area has long been cherished for its beautiful waterfront-scapes, and nearby parks also relate to the history of local castle ruins.

The park is divided into various areas designed for different uses. You can enjoy diverse landscapes, such as multi-purpose lawns for relaxing, open plazas with excellent views over the water, and even areas with sandy shores. Seasonal flowers add vibrant colors to the scenery, especially during the spring when the landscape is filled with bright, colorful blooms. From the lakeside promenade, you can feel the vastness of Lake Biwa right beside you.
While the park shows different faces throughout the four seasons, certain times are particularly special. In spring, the blooming flowers create a colorful and picturesque setting. In summer, the park is a famous viewing spot for the "Biwako Great Fireworks Display" held every August, where the contrast between the fireworks lighting up the night sky and the dark lake surface is truly spectacular. During the daytime, the contrast between the blue sky and the sparkling lake creates a refreshing, resort-like atmosphere.
The primary activity here is walking and strolling along the well-maintained promenades. The paths following the shoreline are perfect for a leisurely walk while gazing at the scenery. You can also take a break in the open plazas to rest and recharge. Visitors can also watch large sightseeing boats cruising across the lake, providing a peaceful and rhythmic experience unique to the lakeside.
The area surrounding the park features various cultural and accommodation facilities. Nearby, you can find one of Japan's leading opera halls, hosting various cultural events. The shoreline is also lined with resort hotels and residential buildings, creating a unique blend of urban life and natural beauty. The coastline also features stretches of sandy beaches and pine groves, offering a variety of scenic changes.
When strolling through the park, comfortable walking shoes are highly recommended. Depending on the season, please bring a hat to block the sun or a light jacket to manage temperature changes. As this is a public space, please be mindful of other visitors. If you plan to use parking lots or nearby facilities, we recommend checking local information in advance.
