A question related to vocabulary
Hi everyone. I'm now working in a translation project, from Japanese to English. There are so many names in Japanese that I need to translate into English, it'll be ok if these names are company's name for instance because these companies usually have their English names determined. But when it comes to other names such as that of movies or services,.. it's pretty difficult, if not to say it's impossible to find the equivalent English names as those movies or services,... are mostly domestic.
So for that situation, I have to write down a note in order to make readers understand that the English names are my translation only and not official English names. What word or phrase should I use to imply that? Please help me with this. Thanks a lot !
