Hi futaro,
Because wordreference forum is divided into many sub-forums,I don't know which sub-forum you orignally used to post your message,but if you would like to translate English into Japanese, you should post your message in other language forum.
your thread was moved to Other languages by me (from Comments and suggestions I think) because only moderators can move threads. You do not have to do anything now. But next time be more careful when choosing the appropriate forum.
