Access DB w/t Japanese Character

When I add Japanese character to access db by <form method=post action="add2.asp">; then, I can read Japanese character through browser, but by opening the database (table) in local, those character get garbage. Oppositely, when I enter Japanese character in the access db table and upload the database in hosting; then, those character looks garbage. Somebody mentioned that I need to convert the character in post method so that I can retain the character. How can I do that? Can anybody help?
