Send My Conscience Home in a Taxi

Just before Christmas, we got this beautiful card (postcard?) from Japan, for one of the previous residents of our house.
Front:

Back:


Anyone out there speak (or read) Japanese?

It's addressed to a "Mrs. Mihori Sotharand", and looks like it's a custom card made by the rather cute family on the front. One of those "family christmas cards" some folks make.

It'd be ace if it's intended recipient saw this! Pass on the word!

Looking at it again, it's got a return address, perhaps I should just send it home... :-(
