Matsuaki Aya, Ouchi Mai is a common Chinese name and there are many actresses with this name. Without additional context, it's challenging to determine which actress you're referring to. If you can provide more information about the actress, such as her full name, notable roles, or awards she's received, I can attempt to translate her name more accurately.
However, based on the limited information provided, I would translate Mai to Mai in English, as it is a phonetic transcription of the Chinese name. It's worth noting that the transliteration of Chinese names into English is not always straightforward, and there may be variations in how different sources render the same name.ko
