Japanese Keyboard is a free iPhone app developed by Christian Rusche. As the name suggests, this app provides a convenient keyboard specifically designed for typing Japanese texts. With a built-in dictionary, it allows users to easily find and select Japanese words while typing in English.

The main feature of Japanese Keyboard is its ability to show users possible Japanese texts based on the English word they type. This eliminates the need to switch to a separate app or perform copy/paste actions. Whether you need to type in Hiragana, Katakana, or Romaji, this keyboard has got you covered.

Overall, Japanese Keyboard is a simple yet powerful tool for anyone who needs to type Japanese texts on their iPhone. Its user-friendly interface and built-in dictionary make it a valuable addition to the Education & Reference category of apps. Plus, the fact that it is free makes it even more accessible to users who want to enhance their Japanese typing experience.
