Kanji characters are one of the most fascinating, but also the most troublesome, aspects of the Japanese language—and that goes not just for foreign learners but also for Japanese natives. The Kanji Kentei is a standardized test that you can take to prove your kanji knowledge, but after being drilled on the kanji throughout their school lives Japanese people might not be taken by the idea of sitting for even more exams on the subject.
That’s why the Kanji Kentei administrators, in an effort to encourage people to give up their free time to study kanji and take their exams, has fallen back on the failsafe go-to of Japanese advertising: cute, nostalgic anime.
