My wife is Japanese, I am Swiss. First, we lived many years in Switzerland, then many years in Japan.
When we lived in Switzerland, my wife has adopted much of the Swiss way of life. I think, that she liked it and also the Swiss "expect" in a way, that foreigners integrate in as many aspects of Swiss life as possible.
Now, in Japan, I don't integrate that much into the culture; the Japanese kind of "expect" me to be, act and dress "foreign". Plus, I like to have bubbles in my bath and refuse to have mayonnaise on my pizza
Basically, we do as we please, adopt, what we like and leave out, what's not for us. We follow some traditions, that are fun and ditch others, that we think, are useless or nonsense. The language we speak bases loosely on English, but is really GermJapLish gibberish, that only us and our dogs can make any sense of, really. Same basic concept goes for what we cook and eat. A mix of everything we like and I have no problem eating sushi with a fork
