Yokohama Yamate Seiyokan Halloween Week

Pull on your costume, bring the kids and stroll around Yokohama for this confusingly named one-day event taking place at a total of 13 locations in the city. Pick up a stamp card at any of the designated spots and start your adventure – free candy will be handed out at every stop, and anyone collecting nine stamps or more will receive a prize at the end. You can also take part in the costume contest, fill up on festival food and have your face painted for a small fee. See the official website for a full map of the day's course, and make sure to arrive early – only 6,000 stamp cards will be available.
