To tie in to the Jubilee, I've put together a UK themed English board. There's a large banner, a fair few trivia questions (with Japanese translations), and various photos.
I'm planning on having the questions up on the board, with the answers covered with a bit of folded coloured paper. The students can then reveal the answers themselves. Debating whether to remove the Japanese translations, but may keep them in to engage some of the less enthusiastic students.
