I have made a couple kahoots for elementary 6th grade and 5th grade using New Horizon books, but mostly for middle school using Here We Go. I use my own photos and such in some of them so feel free to duplicate and change anything you'd like. I have two accounts, you can check out either one.

On ones where it has 聞 in the title, those kahoots have listening practice in the form of needing to match what the ALT reads out loud. For example, on 聞く練習 (答え) questions, I will read out a question, and they need to choose from the choices which answer best fits that question. 聞く練習
(質問) is the opposite.
After each question I usually explain why each other answer option is wrong. This also helps with keeping the class under control because my classes can go wild during kahoot. If your Japanese isn't that good you can ask your JTE to help explain. Explaining is important because it doesn't leave the people who got it wrong wondering why they got it wrong.
I hope this helps!
