Where print personalized postcards?

Hello,
I live in Tokyo for few months and I don't found a shop or a machine for printing personalized postcards with my own photography.
It's not for printing a lot of postcard, just for family and friends, so I think an automatic machine is OK.
Someone can help me? I'm looking for in Tokyo around the Yamanote line.

Thanks to your answers.

Look for 55 station(printing company) near train stations like Meguro and Yoyogi stations.

If you can read Japanese, you can check out their website - http://www.55station.co.jp.

You can even create postcard online - https://www.fdinet.fujifilm.co.jp/fdinet/entrance.do?asp_id=5
