Nipopo doll, sold in Abashiri city, in Hokkaido, are made by prisoners in Abashiri Prison. In an old advanture game 'Oho-tsuku ni Kiyu', this item relates some key point of story, especially the doll cried when case of murder occrured. Therefore, some of old Japanese gamer know this doll cries even though he don't know the reason. Of cource, I visited to Hokkaido and bought it.
