Firstly, this app has been specially created with people who not only are big fan of Apple Watch but also are interested in Japanese words or Sake brewing or Sake / rice wine itself 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 Sake brewery name or Sake brewing process 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 Sake brewery name selecting from a Sake brewery name list page. The third way is also to practice a process of Sake brewing name from a Word list page.

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