Let the Carps Grow: Origami Koinobori

Origami carps are finding new homes now

Would you like to adopt our origami koinobori?

Thanks to your contributions, we now have five fully grown carps (approximately 2.4 metres long) that are seeking new homes.

Please use the form below if you would like to adopt them for classroom decoration, etc. If there is a high volume of requests, we will hold a draw and the winners will be notified via email. The Origami Koinobori will be sent to their new homes via post at our expense.

This origami project finished at the end of May, 2021.
Any information below is for reference purpose only.

Celebrate Kodomo no Hi (Children’s Day) with us as we combine two objects characteristic of the day, kabuto (samurai battle helmets) and koinobori (carp streamers), as part of a fun artistic project.

To get involved, you may drop off your premade origami kabuto in our collection box set up at our library’s front desk, or fold kabuto in person at the library using origami provided by us. Every day, we will continue to join your origami creations to form koinobori with various colourful patterns. We will publish photos of the koinobori growing day by day here on this page so that you can stay updated on their progress, so be sure to check back frequently!

We will raise koinobori in five different colour groups

Message from our origami advisor Midori Furze

Midori Furze

This project was well-received at an origami workshop in Tonga, 2019, which I was invited to by The Japan Foundation. I particularly like that this project is based around the concept that people can work together to create a large collaborative work while anyone can participate in at their own pace. Furthermore, I think this is a project that suits our current situation, where social gatherings are restricted but our desire to be connected with others remains. The Japanese hoist koinobori every year in May, allowing them to swim in the blue skies of spring in Japan. It is these koinobori that wish for children’s good health. I wish that our origami koinobori brings us similar good health here.
