Rengeji-ike Park, Public park and historic pond in Fujieda, Japan

Rengeji-ike Park is a 31.3-hectare general park in Fujieda, Shizuoka Prefecture, centered on a 1.5-kilometer-loop pond. It has about 1,300 cherry trees, 300 plum trees, and 250 wisteria trellises, plus three giant slides, an outdoor music hall, a boat dock, and a Japanese garden.

The pond began as a marsh turned into an irrigation reservoir in the early Edo period, when a dike was built; it was named after Rengeji, a Muromachi-period temple that stood on the hill to the north. In 1869 three local headmen blocked a land-reclamation plan and kept it as a pond. The park was designated in 1973 and opened in 1985.

The park's wisteria, about 250 plants, is the city flower of Fujieda, and the Wisteria Festival runs from late April into May, drawing visitors from beyond the prefecture. A fireworks display is held every year on 7 August. The outdoor music pavilion, built in 1984, hosts festival events and high school choir practice.

The park is accessible throughout the year with plenty of space to walk and explore around the pond. Wear good walking shoes as the paths can be uneven or wet, especially after rain or during rainy seasons.

On the western ridge of the park stand the Wakaoji burial mounds, square and round tombs from the 5th and 6th centuries, protected as a Shizuoka Prefecture historic site. A "Tumulus Square" laid out among 28 of the tombs lets visitors walk right up to them.
