仮名鍵盤 「かなけんばん」 – kana Keyboard
Clicking the button above toggles between:

the button, which displays the words in Unicode entities,

the button, which displays the words in rômaji, and

the button which displays the words in kana.

Use the buttons to shift the keyboard between hiragana, katakana and katakana used for foreign sounds.
Please Note: This keyboard uses a unicode font for the kana characters. For proper display of all characters, in Windows, either install files for East Asian languages under Regional and Language Options in Settings; or install Arial Unicode MS in the Fonts folder; preferably install both.
