Simeji is a Japanese keyboard app that offers an enormous number of customization options and lets you type using kanjis in a very smooth way. To pick from several kanjis, for example, just tap one of the keys for a second and swipe lightly in the desired direction.
Like lots of modern keyboard apps, Simeji lets you customize the look of your keyboard as desired. You can either download themes straight from the app itself or create your own using the images and colors of your choice. The possibilities when it comes to creating your own themes are nearly infinite.
Other interesting features in Simeji include the possibility of transcribing text using the device's microphone or automatically translating any text between Japanese and English. You can also conveniently access several extra keyboards with emoji and kaomoji to use with just one tap.
Simeji is an excellent keyboard app, especially recommended for Japanese users who often need to type in Japanese. The app's customization options are also impressive, with lots of features that are superior to other Android keyboards.
