Yoshihara, 45

 Company employee (Japanese)

It would be convenient, but I wonder if it is really necessary. The current system seems to be working and I don't have any complaints about it. If they started this, I would be worried about security and the leaking of information.

It would be undesirable if private information was leaked. If you were applying for private health insurance and someone could see your medical history, it might affect the ability to get insurance and the amount you might have to pay in premiums.

Akiko Nakahara, 30s

Housewife (Japanese)

I've heard about this issue on the news and at first I thought it would be a good system, but now I'm worried about the possible leaking of information and who is going to be in charge of all the data.

Hide, 50

Electrician (Japanese)

I'm worried about whether there would be just one ministry in charge, or if it would be spread out among different ministries. If the latter, would they be able to share information? It would be convenient, but I wonder if our privacy could be ensured.

Joshua Roccofor, 36

Musician (American)

I'm generally not too crazy about anything like that. Any time you've got a number that is attached to anything, there are security concerns, and I've had my credit card and ID stolen. An ID number might be efficient, but there's probably a better way.

Donna, 21

Student (Australian)

Given that there are so many people in Japan, it might be a good thing. We don't have such a system in Australia so I'm not sure how it would work. It might make it easier to process things.
