Almost all flowers are gone but these bright yellow ones. They're spray chrysanthemums or more commonly known as spray mums.
Chrysanthemums are the symbol of Japanese imperial family, and as some of you may know, the former Princess Mako married her college sweetheart Kei Komuro last week despite challenges, such as her parents' (i.e., Prince Akishino and Princess Kiko)'s opposition and the criticism about Komuro's handling of his mother's financial problem. I found their marriage interesting because it's exposed a couple of issues for the family; can or do the members of the imperial family have human rights; and should Japan keep maintaining the imperial system?
The first question is relatively easy to answer. The imperial family members can and do have such rights. They're human beings and the fact that Mako was born into the imperial family should have nothing to do with her right to marry someone she loves and any other human rights. The thing is, however, that some Japanese are unaware that obstructing their marriage is a human right violation. Even some say that Mako has no right to marry freely because she's a member of the imperial family, and her dependence on taxpayers' money obligates her to seek some kind of approval or support from the public for her marriage.
Chrysanthemums are native to East Asia, but have been cultivated in the U.S. to produce multiple flowers on a stem, then coming back to Japan as spray mums. Things change, and the imperial system is just one such thing.
