Hello, Nanae. Would you mind if I gave you some advice about your choice of words? Please be very careful how you use the words 'foreign' and 'foreigner'. It can be seen as rude to call someone 'foreign'. This word means 'strange''/'different'/'alien'. I am not a 'foreign person'. I'm British, and I live in Britain, so I don't consider myself to be a 'foreign person'. I'm sure that none of the other members who have answered your question would describe themselves as 'foreign people' either.
I understand what you are trying to say when you say 'foreign people'. You mean 'non-Japanese' people. But it can seem quite offensive to when you refer to all the hundreds of nationalities in the world who aren't Japanese collectively as being simply 'foreign'. A more polite way of phrasing this would be this
I have a question for people from other countries.
And to answer your question, yes, I love Japanese food, especially sushi and miso soup. I also really like the taste of ginger and wasabi. What I especially like is that I feel 'clean' after eating it. Some types of food are good to eat, but feel heavy and greasy afterwards. Japanese food isn't like that. It's light, healthy and tasty. Yum.
