I know your original post was a year and a half age, but maybe you or someone will see this. I did answer the original post long ago, but would like to add a little more.
On the position of politics, and whaling for that matter. What is more important, your family or politics. You can exercise your ego discussing politics in a bar with your buddies but most politicians are not worth the effort it takes to listen to them. Your opinion is not of concern to them, only money is, and you or I canft change that. Donft push your opinions on your wife. Take a little test, what is more important to you, what you drive, where you work, your wifefs happiness, what music you like or some blow hard public or political opinion.
On managing wildlife there are many opinions on that. Yours may not be right, or wrong. But no one has the right criticize the Japanese to your wife. There are Japanese people and Americans on both sides of the issue. My wife is against whaling, but if I find someone criticizing the Japanese to my wife for the Japanese position on whaling. The bell for round one has just rung.
You should put your familyfs happiness first. If someone upsets or disagrees with your wife, the best thing to do is what I do. I tell them when they talk to her they are talking to me. If they upset my wife they are down the road period. That goes for anyone. Surprising that is what my wife does also.
There was one item you hinted at, but not mentioned, home ownership. To Japanese women family, and home ownership are of prime importance. Having a nice home is a saving of face sort of thing. It is hard to explain, but the first thing my wife does when new friends come over is to show them our home. That is also the first thing her friends do. When we were first married we did not have a nice home. Even after a while when we owned a farm the house was not up to the standards of most of her friends. Later we bought a beach house. It is embarrassing what I paid for it, but I have paid twice that amount for a small car. I completely remodeled it to her taste, we let the kids live in the farm, and we moved into the beach house, and life became good.
You may be very young, and being such have much to learn. My wife, who is Japanese, and I have been married longer than your mother and father have been alive, so I can say gbeen there done thath.
I hope things have worked out for you both.
