ADDED ON AUGUST 2nd. Sorry if I confused some of you! The straps are cell phone straps and they are all made of plastic! Japanese LOVE cell phone straps (or maybe some countries call them charms?)!
And I just saw this picture today online. It is so amazing I thought I would share. There was a "matsuri" or festival in Tokyo and of course, there were "hannabi" (fireworks) which literally translated means "fire flower"! You can also see the new (and not yet finished) Tokyo tower which is actually called "sky tree".
