池袋弁輸入法 · A Japanese keyboard for learners
Japanese,
one word at a time.
When you know what you want to say but can’t remember one word, look it up right on your keyboard and keep writing.
Available for iPhone. Android APK available; Google Play release submitted for review.
INTERACTIVE EXAMPLE
Start writing in Japanese.
01 / THE KEYBOARD
Keep your train of thought.
e dou is a system keyboard for learners who want to write their own Japanese. Each tool helps with a different kind of pause.
えーと word lookup
Find the word without leaving the sentence.
Tap えーと when you get stuck. Search in Zhuyin, Pinyin or English and choose a Japanese candidate with its reading. The word joins what you’re already typing, so you can finish the same sentence.
xiaguan → 下関（しものせき）
Translation draft
Translate a whole thought when you need to.
Open a separate draft for a full message. Type or dictate the source, review the translation, then insert it where you were writing. The iPhone voice flow starts in the e dou app so you can choose the language you’re speaking.

02 / EVERYDAY PRACTICE
Try it with the Japanese you actually need.
The small gaps in a message are a good place to learn. Read the candidate, notice how it fits, and use it in your next conversation.
Meeting a friend
Where shall we meet?
浅草で会いましょう。
Find 浅草（あさくさ） and finish the rest in Japanese.
Writing an address
A place in Yamaguchi
山口県下関市
Look up 下関（しものせき） when you know the characters but aren’t sure how to read them.
Making plans

04 / FAQ
A few practical questions.
What’s the difference between word lookup and translation?
Use えーと for a word inside the Japanese sentence you’re composing. Open Translation for a full message you want to write or dictate first, then review and insert.
Do I need an internet connection?
Basic Japanese conversion and built-in word lookup run on the device. Cloud translation needs a connection and sends the draft when you request a translation. Dictation availability depends on the selected language and your device settings.
Does the browser example install a keyboard?
It walks you through one sample sentence. The iPhone app supplies the system keyboard.
Can I download e dou now?
Yes. The iPhone app is on the App Store, and the signed Android APK can be downloaded here. The Google Play release has been submitted for review; availability follows approval.
