Sapporo Icicle Festival 2020


Thank you for waiting "Sapporo Icicle Festival 2020" that came this winter!

Icicle is the old name of "Tsurara" and it can also be called a column of ice, which . It was indispensable for the winter scenery in Hokkaido, but recently it has become rarer. It can be said that icicle is a mirror of the environment and art of nature that created in the ever-changing temperature and humidity.

SIAF Lab has been focusing on icicles since 2016 , and has been thinking about the culture and environment of Sapporo and Hokkaido through icicles. The "Sapporo Icicle Festival" has continued to rediscover the winter in Sapporo by considering the icicles declining in our daily lives from the perspectives of art, science, and culture. Furthermore, this year, as a culmination of our efforts so far, we introduced works that has been changed day by day for the winter environment in Sapporo in a more attractive way.

Spectral Icicle of Milieu

Icicles are objects made from water by the  environment, but if we replace water with other materials, what will happen?. This work expresses icicles as a wall of light based on the environmental information (temperature, humidity, atmospheric pressure) acquired in real time.


Artificial Icicle Making Machine

The production of this device started from the short sentence,  "I want to sing icicles!" said by a SIAF Labl member. This device, which  can control the amount and angle of water by computer to create artificial icicles that can’t be found in nature, has undergone numerous experiments and trial and error. It  showed us icicles with different shapes this year.

Rotating Icicle Forming Machine

Radial icicles created from sticking water droplets sprayed onto a rotating shaft. An impressive and mysterious rotating giant icicle installation. The size and formation of icicles change according to the weather conditions of the day.

The Icicle Hut

What a building made from icicles would look like?. This hut, which is called a icicle hut, has a special structure controlling the transmission of  heat to make the formation of icicles easier. How big and what shape will the  icicles be this year?
