A countermeasure against “three-year-old children with wings”
Crows are really as smart as humans. So we asked Mr Sugita known as “Dr Crow”, a professor of animal production science at Utsunomiya University, to work together. We successfully developed a new device designed to keep crows at bay by using the intelligence of the bird.

Keep crows away by just hooking Iyagarasu
果樹園から牛舎、ベランダまで様々な場所に設置できます
As it is made of stainless, Iyagarasu is very light. And it can be easily used by just hooking.
To counter against crows breaking into various places relentlessly, the device needs to be placed everywhere. This item alters territorial disputes with crows to your advantage as it can be used wherever you need.

With pride as a spring producer, we are “bound” to stop crows from making you cry.
We usually produce springs, which are used in various places of life. Having supported your life for a long time behind the scenes, we wanted to help farmers and ordinary people who were feeling the fear of crows every year.

Springs are the symbol of our company

I was waiting for such an item!
I was waiting for such an item. Vegetables were
targeted by crows, which was a real headache.
Its effect was more than I had expected. I apply
it to cucumbers now and use 40cm-type of
Iyagarasu with wings in the fields, which swings
well and shows good effect on crow removal. I'd
prefer the one with wings to normal one. It'll be
great if propellers are sold individually. I am
arranging the device and learning by mistakes.

Wishing crows a happy life
Our aim is not to ill-treat crows
but to co-exist with them.
It is the fact that humans are seizing
the territories of other animals. So,
returning crows to the wild is one of
our missions. In the production
development process, the love of
animals was a priority for us too.
