This is a simple game app that explains katakana words in Japanese.

The questioner explains randomly displayed katakana words without using katakana words.
Other than the questioner, if you listen to it and answer what katakana word it is, you will get points.
It can be enjoyed by two or more people with one smartphone.

Since it is a simple game that katakana words are displayed every time you tap the button, you can freely decide the rules such as the time limit and order.
You can also change the number of displayed katakana words, so you can choose your favorite katakana words for the question.
