Nintendo’s first dedicated mobile app, Miitomo, is due for release in the West this month. In the meantime, Nintendo is busily promoting the app, which launched in Japan this week, with the latest trailer above showing off just what you’ll be doing in Miitomo.

Not surprisingly, you’ll be creating a Mii avatar, but you’ll also be able to customize your character more than ever, from the tone of your voice to your personality, and of course the clothing style of your Mii-self.

It looks like the app is a chat app of sorts, where your Mii will ask a question of you, and post your answer to your friends, to which they can reply.

Check out the video above to learn more about Miitomo and let us know your thoughts in the comments section below.
