Hamanako Garden Park

Hamanako Garden Park is a 33-hectare public park located on the shores of Lake Hamana in Shizuoka Prefecture, Japan. The park was originally developed as the site for the Pacific Flora 2004 international horticultural exposition, which attracted over 6 million visitors during its six-month run. After the exposition concluded, the site was transformed into a permanent public park that opened to visitors seeking recreational activities and natural landscapes along Japan's largest lake by area.

The park showcases diverse botanical collections across multiple themed gardens, including a Crystal Palace greenhouse that houses tropical and subtropical plants year-round. Seasonal flower displays feature tulips in spring, sunflowers in summer, and cosmos flowers in autumn, creating rotating displays throughout the year. The park's design incorporates Japanese garden aesthetics alongside international garden styles, reflecting the horticultural themes of the original exposition. A 50-meter observation tower provides panoramic views across Lake Hamana and the surrounding Enshu region, allowing visitors to appreciate the relationship between the cultivated gardens and the natural lake environment.

Visitors can explore the grounds via walking paths, rent bicycles, or board a small train that circuits the park. Water activities include boat rentals for touring the park's canals and waterways. Children's play areas, lawns for picnicking, and shaded rest areas accommodate families spending several hours at the site. The park includes several restaurants and cafes serving regional Shizuoka specialties, and shopping facilities offer local products and plant-related goods.

Hamanako Garden Park is accessible from Hamanako Garden Park Station on the JR Tokaido Line, with the park entrance located directly adjacent to the station. The journey from Hamamatsu Station takes approximately 20 minutes by local train. Visitors arriving by car will find parking facilities on site. Admission to the park is free, though certain facilities such as the observation tower and greenhouse charge separate entrance fees typically ranging from 300 to 500 yen per person. The park remains open throughout the year with seasonal variations in garden displays.
