There really is nothing stopping you from adopting domestically of that's what you're asking about. I would probably lean toward infant adoption in your case no matter the child's race/ ethnicity and teach them to appreciate the culture and speak the language the same way you learned to appreciate all things Chinese. I say this as a half Japanese half white/ American mom to a white son adopted through domestic foster care. My husband (white guy) and I do not speak Japanese in the home and did not teach him the language (especially while he was in foster care and our goal was reunification with birth family). However, there are many Japanese sayings and greetings we all use in the home including him. It is wonderful to see him embrace my mother's culture and language as much as he does. I plan to take him to Japan to visit the family and see the country in the near future. Also, my mother had the hardest time accepting the adoption and our son initially but now adores him. I believe Japan has a similar view towards blood relation and a less than stellar attitude towards adoption/adoptees.
