The Japanese really dig doodads that dangle from their phones, purses and backpacks. These can be obtained nearly anywhere but my absolute favie is their bubble machines (also called Capsules.) Plug in 200 yen (about $2 US dollars), twist the handle and collect your prize. Here is my collection from this particular trip.

Some of them are so ornate and detailed (and bizarre!) from the asparagus stalk phone charm to the DIY theater seat (complete with separate soda to place in the drink holder.)
My Entire Collection from All My Trips & When I Lived There
And yes, that is sperm charm the red arrow is pointing to.
