About This Documentation
What Is Life Like Inside a Cage?
This website documents the reality of cage egg farming in Japan through a daily record of life inside a commercial egg farm.
All of the photographs, videos, and written records published here were documented inside the same egg farm.
The housing conditions shown on this website reflect the conventional cage systems that are still widely used today.
Rather than focusing only on exceptional incidents or the worst moments, this website records the ordinary reality of daily life inside the cages. Events are presented one day at a time, in chronological order. Each video and accompanying description documents only what was observed on that particular day.
Although this is the record of a single farm, it reflects many of the welfare problems commonly found in cage egg production.
What This Documentation Shows
The purpose of this website is simple.
By understanding the reality of cage egg farming, both consumers and companies can choose cage-free eggs.
We hope these records provide the information needed to make that choice.

Life Inside the Cage
What do hens experience inside cage systems?
The scenes shown below are not rare or exceptional—they represent conditions that occur routinely in cage egg production.

Pecked and Featherless
Weaker hens are often pecked by other birds until much of their feathers are torn away. Inside a cage, there is nowhere to escape. Losing their feathers causes severe stress for the hens.

Trapped in the Cage
Some hens become trapped in gaps around the egg collection area, leaving them unable to move.
Unable to reach food or water, some die where they are trapped.

Severely Injured Foot
This hen has lost almost all of one foot.
The injury appears to have been repeatedly pecked by other hens.
No veterinary treatment is provided.
Voices of Support from Around the World
Japan’s continued use of cage systems is drawing attention from around the world.
Animal protection organizations overseas are also supporting Inside the Cage and adding their voices to calls for change in Japan.

Message of Support (English Translation)
“In the name of limitless productivity, most laying hens have been reduced to machines that produce more than 300 eggs a year, at an enormous cost to the hens, who are more exhausted than ever before in the history of their species. As if that were not enough, they have also been deprived of natural light, fresh air, and the space to move around or even stretch their wings. This must change.”

„În numele productivității fără limite, majoritatea găinilor ouătoare au fost reduse la niște mașinării care depun peste 300 de ouă pe an, iar asta vine cu costuri imense pentru bietele găini, mai epuizate ca oricând în istoria speciei lor. Fiindcă nu era suficient, acestea au fost private și de lumină naturală, aer curat și spațiu să se miște ori măcar să-și poată întinde aripile. Acest lucru trebuie să se schimbe.”

AnimaNaturalis

Message of Support
“At AnimaNaturalis, we stand firmly with ARCJ and the Inside the Cage campaign. Cages cannot be reformed to be made acceptable — they must be abolished entirely. In Japan, around 98.5% of laying hens remain confined in wire cages, unable to spread their wings, lay their eggs in a nest, or perch, denied any semblance of a dignified life. Ending this system is an ethical responsibility that knows no borders: what happens inside those cages in Japan concerns us as much as what happens on farms here in Spain. We strongly urge companies and decision-makers in Japan to commit to a cage-free future and act without delay for the welfare of these hens”
