Japanese !!! it's 5/18/17
Japanese hasn't launched on the web yet . Why is that ???
It's still not even 2:00 AM on the west coast of United States. They'll most likely release it during the day, which sadly means evening/night for the rest of the world.
Japanese has launched on iphone only, so far. According to the most recent post (3 days ago) on the incubator: "The course will launch into beta phase on May 18. Please be patient until we support the course on all platforms. Because of "something new", we'll need an extra effort to support the course on different platforms. Thank you for understanding and look forward to the Japanese course!" Hope this helps!
