People

Controversial people are more likely to appear in this list because they attract more media attention than regular people just living their lives day by day. Additionally, controversial people may be more focused on giving up their original nationality as opposed to acquiring Japanese nationality.For every person listed here, there are hundreds of thousands of people who are naturalized who go about their daily lives without ending up in the news. You should not expect that average naturalized people have the same experiences or opinions regarding naturalization.

Note: there are some cases where the official legal name(s) (pre-naturalization or post-naturalization) of a person have not been confirmed or acknowledged. In these cases we use the names they use in public and the media. Some people continue to use stage names or their original names even after they naturalize.
Names are sorted in Japanese dictionary order by their naturalized names.
