Kiso Sansen Park is an urban city park located in Kaizu City, Gifu Prefecture. The park first opened in 1987 and is the largest urban park in all of Japan. In fact, it is Japan’s largest National Government Park with the whole park straddling Aichi, Gifu and Mie Prefectures. The center of the park is located in Kaizu City, from which visitors can see the surrounding area which includes the Nobi Plain and Ise Bay.

The name Kiso Sansen refers to the three great rivers (Nagara River, Kiso River and Ibi River) that all pass by the park.

The great thing about this park is that it can be enjoyed all year round with the beautiful seasonal flowers that adorn the park. It is also ideal for families with a large children’s playground called “Adventure Land” that is filled with lots of fun playground equipment and facilities. There is a large grassed area for sports, and it 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” with the flowers representing the three rivers and famous waters of the area. The flowering season is between April and May with a range of early, middle and late flowering tulips.


The park also has an observation tower that offers spectacular views of the surrounding area and the three famous rivers. You can see 360 panoramic views from the top of the 65 meter tower. There is also a cool exhibition center in the tower as well that presents the history, climate and nature of the area. The exhibition center is very interactive with lots of information, attractions and games that can be enjoyed by the whole family. Entry to the tower is 600 yen for adults and 300 yen for children.
