The first thing you should do is contact your credit card issuer to have
them cancel your credit card as soon as you notice the card is missing.
You should also report the missing credit card to police. Even after you’ve
gone through the necessary procedures, unauthorized charges are made with
your credit card, and you have no grave negligence, many credit card issuers
have some kind of insurance to protect credit card holders from fraudulent charges made with your lost or stolen credit
card. Consult your credit card issuer. Japan Credit Card Association.

You can make an inquiry with the Taxi Center
(06-6933-5618.5619) to see if they have received a report of your missing purse
from a taxi you took. If you cannot locate your purse at the center, report the
loss with police and at the same time, have your Alien Registration Card reissued
within 14 days of the loss of your card.
