actually its mainly Korea where Dog is a delicasy....
oh and Nyororin is a Lady
i dont think its fair to put a animal through the trauma of quarentine just for your own selfish wants; best to let it stay with people that can look after it; then if and when you find a place in japan that will accomidate your pet wants and needs; then start to look for one.
one point; if you plan to work in japan; hours and commutes can be long; having a dog maynot be ideal as it'd be even more tiring to look after it after a hard day at work...
