But I strongly encougage you to contact any station along the Nankai Line as soon as possible. For example, the phone number of Nankai Line Namba station is 06-6631-1351.

If anything is found inside the station, it will stay within the railway company for about a week. Also, if you contact them now and they say they don't have it, try again a few days later. Small items often show up after a time lag.

If you happen to have any language barrier, ask your hotel or an information counter for assistance. Good luck.
