Japan is still in a situation where 99% of eggs are produced from battery cages, and the industry is clinging to this old rearing method. However, there will be no future there.
In USA, sale of caged eggs have been banned starting in Massachusetts, then in California, Washington, and Oregon. Furthermore, Other states tried to ask the Supreme Court to repeal the law in Massachusetts but the Supreme Court did not accept the lawsuit.
Eggs in the US are inexpensive. Unlike in Japan, it must be advantageous to be able to produce feed within the country, and to have large production volumes with large facilities.
It seems that Japan wants to sell eggs overseas, but are battery cage eggs still even accepted? It will be difficult. Although common sense would indicate that the demand from the world will never increase for eggs that totally oppose animal welfare — eggs from not even enriched cages but battery cages that completely limit the dignity of the hens and the natural behavior of these animals, coupled with
detection of insecticides (pesticides) — the country and the industry seem to have different prospects.
