Respect for the Moon and Rabbit Day

I love owning a Japanese cell-phone. We don't have fancy ones; they don't take pics or flip open with a reassuring little "ping", although we can do e-mail. No, we just have non-posh, run of the mill, Tuka phones.

What I love about Tuka is the little pics they send to our phones on special "days". Today, for example, is "Respect for the Aged" Day in Japan (I tried to get Matt to make me breakfast in honour of it, but he didn't get the hint). The quaint thing about Respect for the Aged Day was the pic we received from Tuka this morning.

A beautiful little diorama of two embracing bunnies under the full (and smiling) moon. Is there some link between rabbits and old people that I don't know about?
