Here is the message I received from them:

We would like to express our deepest thanks for your article and comments regarding the ‘Japanese in Anime & Manga’ website (http://anime-manga.jp, produced by the Japan Foundation, Japanese-Language Institute, Kansai).
We have just added two new sets of contents to the site, a “Ninja Kanji Game”
and “Samurai Expressions by Scene”. Please take a look!

More good stuff to learn a little bit of Japanese in a fun way!
