Lost Phone found by Bus Company but they don't ship internationally

I recently went to Japan as part of a school trip and lost my phone on the Bus Ride to Haneda Airport. I got an e-mail that said my phone was found, but they said they do not ship internationally. I do not have any friends or family who live in Japan either.

What options do I have at this point? I very much do need my phone as I rely on it for a lot of 2FA, but the idea of buying a plane ticket to retrieve my phone is not exactly economically responsible at the moment.

Edit: Looking at the e-mail again, I don't think they ship at all as they said to respond with a date for retrieval.

Update: I was able to get in contact with one of the former foreign exchange students at my University through one of my professors. They were able to pick up my phone for me and are currently looking at shipping my phone to me.

Before my professor got back to me; I was looking at [https://ossanrental.thebase.in/?utm\_source=Tofugu](https://ossanrental.thebase.in/?utm_source=Tofugu) though I can't say how well it would have worked as I did go through with it. Would have likely required contacting them through their listed contact information and negotiating with them.

The Bus Company suggested [https://www.japan-lost-item.jp/eng/](https://www.japan-lost-item.jp/eng/) but I have heard rather mixed reviews on it.
