While word lists from March on are for members, any word lists prior to that are free to everyone, and always will be.
Here is the Hello Kitty word list. I got the words from an article (which is linked at the top of the list) about a Hello Kitty exhibition in Los Angeles. If you want to practice listening, the Hello Kitty YouTube clip is there for you too. (and at the top of this post)
Each month we put out new subjects. An article, 30 words, and a test on 10 of the words (but you don't know which 10). This is followed up with your test result, and 30 more English/日本語 definitions.
The subjects for April are: Cherry Blossoms, Who is going to look after Japan's elderly?, and Caroline Kennedy.
Send us an email at firstname.lastname@example.org to find out how you can try one, two, or all three of these subjects in your free trial month.
