Japanese use Chinese characters which can have several ways to pronounce. It's difficult even for a Japanese person to properly pronounce names because they most often use Chinese characters. As such, there are fields to Last Name, First Name, and Address fields (furigana fields) on how they are pronounced. These fields are often used to soft rather than the Last Name, First Name, and Address fields themselves.
These additional fields are present in all Japanese documents including names.
I would like to have these fields available for Japanese users.
