Just before boarding my flight home to Hokkaido I realized I left my airpods at Kansai Airport in the waiting room at my gate 🙁 It was the one lucky flight this past Sunday that was able to fly out due to bad weather in Chitose, Hokkaido so I couldn't at all go back for it. Does anyone know where this is or any tips to maybe try to get it back? It was left in KIX but someone seems to have picked it up and traveled at this location with it. My number should be there during lost mode but they might think not to call bc it is different US area code.

I want to see what my chances or if I should accept the L and get a new pair for Christmas. I've had them for about 4 years and they were a gift from my mom so hopefully I can see what I can do but it's not the end of the world if I don't
