Lost and found luggage

A suitcase belonging to me was left on a train at Tokyo central this morning (20th May) at 8.45am.
I boarded the wrong train and got off at the next stop and went back to the station to board the 9am NEX express to Narita airport.
I forgot to collect the luggage on the rack and had no time to report it as I was late boarding the train (Nartia express 13) to the airport.

Also, on the luggage is my full address details and a photocopy of my passport in the zippered panel of the suitcase.

So sorry for this gross oversight on my part, but I hope you can locate and return to me.

Regards
Chris Kirkpatrick.
