I am currently travelling in Japan and finally saw horses in the Mount Aso area, which is in the southwest. Most of them were draft or draft crosses, pastured with cattle, so thought they are probably being raised for meat. Also have seen horse on the menu in several restaurants and no, I did not try it!!!
Have travelled quite abit around the country on mostly trains, some buses and most of what you see is rice paddies. No cattle or other livestock, not until I was in the area mentioned above finally saw cattle. Have been travelling up the east coast above Tokyo the last couple of days and have seen several trucks carrying cattle, but no farms.
Although, I personally don’t like the idea of horses being eaten but here and in Europe, it is part of the culture. Other countries import livestock for food. Yes, the shipping conditions need to improve. If we were to look at horses as just livestock, like cattle, pigs etc., we probably wouldn’t not have a problem with them being eaten.
