If you've played Cards Against Humanity, then you know how to play this game!
I didn't come up with this idea, but I thought I'd share my materials to hopefully save someone else some time.
There are two types of cards; black and white (I printed a black pattern on the backside of the answer cards). Students make groups of 4-5 people. Each student is given 5 black cards and the rest are placed in the middle. The white cards are also placed seperately in the middle. One student takes a white card and reads it to the group. For example, "I like ________." The other students must choose 1 of their cards to fill in the blank. The first student then chooses which of those cards they agree with the most. This is a little different from CAH because the aim is to use the students' knowledge of their classmates, not necessarily to make a funny answer. The person who played the winning card then recieves the white card as a point. It can also work as an ice-breaking activity for new classes!
I find that the best way to explain this game is through a demonstration. I choose a model group and have the other students gather around as we play one round (I will take the first white card). This way students can understand how to play the game without giving any instructions in Japanese.
I've mainly used vocab and grammar from ES, but it still makes a good review for my JHS as well. You could also level up the game by changing the content on the white fill-in-the-blank cards.
Feel free to edit the cards as you see fit (you will have to make a copy first). Here's a link to the Google Sheets:
