We’ve had many requests for including japanese characters in the Twitterfountain animations. The reason this feature wasn’t included from the start is that the twitterfountain animation cannot use system fonts (for example, a Japanese font on the computer of a Japanese user). System fonts simply don’t look very good when used in animation!
We’ve finally come up with a solution. When displaying a Twitterfountain, you can open the settings menu and click ‘load kanji’. This will load the Japanese characters (Kanji and Kana).

Loading Japanese characters (also usable to display Chinese) comes with a small price: an additional download of 1MB. By comparison: the regular font is just 16KB.
When embedding a fountain, you can choose to load Japanese characters by default. Just tick ‘load kanji’ before getting the embed code.
Please preview the new font-enabled Twitterfountain and tell us if you find any irregularities! When all goes well, we will replace the old TwitterFountain.
