Overview of De Rijke Park
The park was completed on April 15, 2009. Otani River flows through the grounds, where the historic De Rijke Weir remains as a reminder of the engineering work undertaken to control erosion and prevent sediment from washing downstream. Its distinctive curved stone structure is both functional in design and visually striking, blending naturally into the surrounding landscape.
The History of the De Rijke Weir
The De Rijke Weir was constructed between 1886 and 1888. Measuring approximately 97 meters in length and 3.8 meters in height, it is one of the largest surviving weirs associated with Johannes de Rijke in Japan. The structure remains in remarkably good condition, with its stone-faced surface demonstrating the sophisticated construction techniques used at the time.
In 2002, the weir was registered as a Tangible Cultural Property of Japan in recognition of its historical and engineering significance. Today, it stands as an enduring example of the efforts made to protect riverbanks and surrounding communities from erosion and sediment runoff during Japan’s modernization.
Seasonal Beauty and the Tulip Festival
One of the park’s main attractions is its spectacular spring display of more than 10,000 tulips. During the annual Tulip Festival, the grounds burst into color, creating an inviting setting for photography, leisurely walks, and picnics. Festival activities and small market stalls beneath colorful parasols add to the lively atmosphere, attracting families and visitors from across the region.
The park is worth visiting throughout the year, too. In summer, the lush greenery and the flowing waters of Otani River create a refreshing natural setting. Autumn brings beautiful foliage, while winter offers a quieter atmosphere and a different perspective on the surrounding scenery. Each season reveals another side of this small but historically significant park.
Johannes de Rijke and His Contribution to Japan
Johannes de Rijke was a Dutch civil engineer invited by the Japanese government during the Meiji era to help improve the country’s rivers and flood control infrastructure. At a time when erosion and sediment accumulation posed serious challenges, he contributed expertise in river engineering and guided projects involving weirs and other structures designed to manage water and soil.
The De Rijke Weir was part of this wider effort. Working under his guidance, local engineers and workers built the structure across Otani River to help prevent sediment from flowing downstream. Its continued survival illustrates the lasting value of the engineering knowledge introduced to Japan during this period.
Getting to De Rijke Park
By Car
The park is conveniently located in the central area of Mima City. From Wakimachi Interchange on the Tokushima Expressway, the drive takes approximately 8 minutes. Parking is available at the park, making it an easy stop for visitors traveling by car, including families and small groups.
By Public Transportation
Travelers using public transportation can take a JR Shikoku train to Anabuki Station, then continue by taxi or bus. Bus services in the area are limited, so check the timetable in advance and plan your journey accordingly.
Nearby Attractions
Udatsu Historic Streetscape
About 10 minutes away by car, the Udatsu Historic Streetscape in Wakimachi preserves traditional merchant houses and storehouses dating from the Edo period (1603–1868) through the Meiji era. The distinctive firebreak walls known as udatsu rise above the roofs, reflecting the prosperity of the merchants who once lived and worked here. A stroll through the district offers a fascinating glimpse into the region’s history and traditional architecture.
Mima City Museum
The Mima City Museum is another worthwhile stop for visitors interested in the area’s heritage. Its exhibitions introduce the local history, culture, and natural environment, helping visitors gain a deeper understanding of Mima City and its surroundings.
A Scenic Park with a Remarkable Engineering Legacy
De Rijke Park brings together seasonal flowers, peaceful riverside scenery, and a valuable monument to Japan’s modernization. The historic weir, built under the guidance of Dutch engineer Johannes de Rijke, gives the park significance beyond its natural beauty. Visit in spring to see thousands of colorful tulips, or combine a relaxing walk through the park with a trip to the historic streets of Wakimachi. For travelers exploring Mima City, it is a rewarding place to discover the connection between landscape, history, and engineering.
