I had a late arrival at Haneda and dashed through immigration because I was worried about catching the last train. I didn't notice that the immigration agent did not give me the small piece of the entry document that is torn off, kept in the passport, and returned when leaving the country. When I realized that I didn't have it, I figured that I was going to have the opportunity to learn what happens when someone loses that paper.

However, someone told me that there is a new entry document for Japan, and that the new form does not have the piece that gets torn off and kept in the passport. I used the old form when I arrived, and I can't find mention of a new immigration document in the forum here.

Does anyone have any information on this? Will I have problems on departure because I don't have the paper in my passport? Thanks!
