After converting driving license

Hi.
I`m from Italy living in Japan with an Italian driving license. I know that I don`t need to take any test to covert it, but I would like to know what I have to do once I get the Japanese license: must I give my Italian license back? Or can I keep both?
If somebody has gone through this and could help me out I would be very thankful!

As for me with a German license I didn't have to turn it in. Got it translated to Japanese (by JAF??), paid my fee at the license center, took my eye test, watched the video and listened to the briefing and got my Japanese license. That easy. I still got my German / European (pink) license and use it whenever I return home (to Germany, of course). Hope this helps?!?!

Why on earth would you have to give your Italian license to the Japanese authorities? It has nothing to do with them and would be damned inconvenient should you happen to return to Itlay on holiday and want to drive.

A lot of publications misleadingly explain the situation as "exchanging" or "converting" your license into a Japanese one. As others have pointed out, you just keep your Italian license afterwards.
