Calling for submissions for the First Ikimon Coloring Contest!

Sep. 23, 2020

Ikimon means "living organisms" in the Japanese Kansai dialect.

The bodies of living organisms are very complex, and at the same time, very beautiful. This is why we decided to make a coloring page featuring living organisms!

The theme this time is "The Lungs". Humans breathe air in and out of their lungs roughly 20 times per minute or 30,000 times per day. What does the inside of the lungs look like? Inside the lungs are many tubular structures in which air passes through. These tubular structures are lined with various types of cells, with each cell type having different functions.

Imagine the drama taking place inside the lungs as you color the cells that make up this organ!

Submission period:
September 23 – October 20

How to enter the contest:
Download the coloring page from the website, color the picture, and submit using one of the following two methods. If you prefer to print and color, please download the PDF version.
