Can I stay in a hotel without a foreigner landing card?

Passports are also valid documents, which can be used as check-in documents, not just ID cards.

When you go out, as a substitute for your passport, please be sure to bring the "Alien Landing Certificate".

If the police want documents, we have an obligation to show them. Because I carry it with me every day, it may be lost or stolen.

So write the login number in other places (such as your notebook) and keep it safe. Similarly, passports should be kept in this way.
