Kiso Sansen Park also called Kiso Sansen Koen is an urban city park located in Kaizu City, Gifu Prefecture, Japan. The park first opened in 1987 and is the largest urban park in Japan. Kiso Sansen (木曽三川) refers to the three great rivers that all pass by the park. The three rivers are the Nagara River, the Kiso River and the Ibi River.
The park can be enjoyed all year round with its beautiful seasonal flowers and large grassed area. There is a large children’s playground with lots of facilities and the park is an ideal place for relaxation, recreation and time together with the family.
Kiso Sansen Park comes alive with colour every spring with the famous Tulip Festival. There are around 260,000 tulips and muscari bulbs with about 125 different types and lots of amazing colours. The tulips are arranged and designed in the theme of a “flowing river” and the flowers represent the three rivers and famous waters well.
There are many different types of tulips in the park including the popular single flowering type, double, lily-flowered, parrot and fringe tulips. The flowering season is between April and May with early, middle and late flowering tulips.
The Observation Tower offers spectacular views of the surrounding area and the three rivers (Nagara, Kiso and Ibi). You can see 360 degree panoramic views from the top of the 65 meter tower. There is an exhibition center as well that presents the history, climate and nature of the area and is very interactive with lots of information, attractions and games that can be enjoyed by the whole family.
