Woke up this morning and was quite surprised to see this mt fuji from my balcony. Up till this morning, mt fuji was still without her "white cap", but I guess the temperature has really gone down last night.
You will find this, or something similar enough, in every Japanese office and dormitory (as far as I know). It serves as a "status indicator", i.e. whether you are in or out. Finding mine in the picture should not be difficult.
