There are a lot of ways to celebrate Halloween in Japan. You could go to the Kawasaki Halloween Parade — one of the biggest parades in the nation — join a school party or dress up and head down to Shibuya Crossing to drink with ゾンビ (zonbi, zombies), 狼男 (ōkami-otoko, werewolves) or 鬼 (oni, demons).
However, this year Halloween falls on a Tuesday and the aforementioned events all took place over the weekend, which means the scariest thing you're likely to encounter on Oct. 31 is the commute home after work. Fear not (pun intended): One good way to inject some 恐怖 (kyōfu, fear) into your Halloween night is a good old-fashioned ホラー 映画 (horā eiga, horror movie) marathon.
If you're going to binge-watch a bunch of 怖い (kowai, scary) films, learn a few Japanese words and phrases to practice shouting at the screen and kill two birds with one stone (一石二鳥, isseki ni chō).
