Halloween has come a long way from its origins in Christian festivals for the dead and ancient harvest festivals marking the end of summer. These days it's more about looking as silly as possible (no, even that Scream costume is not scary), a custom that was popularised in the US in the early 1900s. In Japan, too, there is none of the doom and gloom of the holiday's historical association with death, which may have something to do with the fact the celebration first made waves at Tokyo Disneyland.
Even if you're not planning an all-nighter on the last weekend of October, it's still worth heading down to Shibuya or Shinjuku just to laugh at the outlandish costumes on show. And if you're one of those donning an outlandish costume, check out our event guide for both All Hallows' Eve and the week before the big day.
