Firstly, this app has been specially created with people who not only are big fan of Apple Watch but also plan to visit Japan or are interested in Prefecture name of Japan or Kanji letters in particular. And, you can also select between 2 languages, such as English or 日本語, at the bottom of the page.

Secondly, on this app, there are three ways to practice Japanese letters, Kanji that relates to Prefecture name of Japan in particular. The first way is to practice a single Kanji letter selecting from a Letter list page. The second way is to practice a Prefecture name selecting from a Prefecture name list page. The third way is also to practice a Prefecture name though; you can make sure where each prefecture is located in Japan the Digital Crown before practicing a Prefecture name you have chosen on the map.

Lastly, I would like you to feel like having a bit of Kanji letters and a simple map of Japan up your Apple Watch, as the saying goes, "have something up one's sleeve."
