Odd Request / Question: Appliance Delivery / Pickup Proxy (“key holding”)

Weird one. I am not sure that this exists, but I am looking for a service in Tokyo that could help with a furniture rental pickup while I am out of the country.

I was schedule to leave Japan in a 3 weeks, but have to return home fairly urgently. Managed to get everything packed up, cleaned out and sorted in the apartment BUT I have a rental refrigerator in the apartment and it looks like the earliest it can be picked up is next Wednesday.

Curious if there is any sort of legitimate "key holding" company that could come into the apartment, open the door and allow the delivery people to pick up the fridge, and then lock the door and return the key to the mailbox when they are done. Landlord is okay with it.

The apartment will already be fully cleaned out and empty, so fairly simple request. It seems like there are lots of disposal and junk removal services that can do un-attended clean ups and key return, but not sure if that would be applicable. Although, maybe an easy job for them that day.

Any ideas / help would be greatly appreciated!
