Nakajima Park is an extremely popular park in Sapporo. It one of the main three. The other two being Odori Park, and Maruyama Park. Since 2004, a new festival has started in Sapporo, that being the Autumn Illumination Festival. It is held in Nakajima Park in the evening and is truly stunning. During the day there is a Red Terrace Event on, in one section of the park. This has a dozen stalls and an eating area. They sell mainly sweet potato dishes. During the evening, it is lit up with hanging lights and is quite romantic. At 18:00 is when the real magic happens. Places in strategic spots around the park, the trees are lit with colored lights. Red, yellows, and greens. What makes it particularly beautiful is the reflection on the water from the central pond in the middle of the park. The Japanese Gardens inside the park are also illuminated and are a must see. 

There are some events that are held out through the park to add to the experience. At the Hoheikan Hall building, there is the Meigren Dance Performance. This is a traditional geiko dance and is performed by geisha in their beautiful kimonos. Each dance goes for 15 minutes. There is also a tea ceremony at Hoheikan Hall where you an enjoy Japanese tea and sweets. There is also a tea ceremony in the Japanese gardens by the Hasso-an (Tea House). Oshiruko is sold here. Oshiruko is a traditional Japanese dessert made from sweet red bean paste and mochi.
