A number of vending machines are put along the wall in Akihabara station.
This is called “Gachapon” or “Gachagacha” and there is a miniature animal or food toy in a capsule. As all the miniature toys are elaborately made, they are popular among adults as well as children.
By the way, I have been collecting “Akabeko” a traditional folk craft of Fukushima Prefecture.
