Many thanks to those of you who answered my poll (Poll: Show alien registration card when re-entering Japan?) and left comments via the post, Google+, Twitter, etc. (Commenters, you're mentioned in the article below!)
If you're interested in reading everyone's comments and the results of the poll (as of the date of the column), check out:
To carry or not to carry your 'gaijin card' upon re-entry? - Japan Times, October 25th, 2011
Also, if anyone has an interesting story to share about being stopped at Immigration without their alien registration card, please let me know, and I may use it for a future column.
Happy weekend to everyone!
