Alongside the big Splatoon content update, Nintendo also launched a dedicated Splatoon web app today. Once you log in with your Nintendo Network ID, there are several functions available to you:
Friends List: See which of your friends are online and send messages to your friends inviting them to play Splatoon with you.
Ranking: View your friends’ current ranks, levels, gear and how many points they’ve scored with each weapon.
Equipment: View your own profile. Only works if you’ve updated your game to version 2.0.
Schedule: Check out the current and upcoming map rotation.
The catch, however, is that the website is only available in Japanese right now. Hopefully we’ll see translated versions of it soon.
