About this app

Type Japanese easily with Koto – a fast, customizable Japanese keyboard for Android.

Koto Japanese Keyboard gives you multiple ways to type Japanese, including Kana flick input, Romaji typing, Hiragana, Katakana, English, and offline Kanji conversion.

Whether you're learning Japanese, chatting with friends, writing notes, or typing every day, Koto provides a simple and comfortable Japanese typing experience.

JAPANESE KANA FLICK KEYBOARD

Type naturally using a Japanese-style Kana flick keyboard.

• Tap for あ
• Flick left, up, right, or down for い・う・え・お
• See Kana alternatives directly on each key
• Use ゛ for voiced and semi-voiced Kana
• Use 小 to quickly type small Kana such as ゃ, ゅ, ょ and っ

ROMAJI JAPANESE KEYBOARD

Prefer QWERTY typing? Use the built-in Romaji keyboard to convert Roman letters into Japanese.

Examples:

• nihongo → にほんご
• kya → きゃ
• shi → し
• tsu → つ
• doubled consonants → っ
• nn / n' → ん

Switch easily between Hiragana, Katakana and English while typing.
