There are three types of Japanese script-katakana, hiragana, and kanji.
It is possible to read Japanese knowing only a limited number of kanji,
but it is not possible with only a limited number of katakana or
hiragana-one must know all of them. Let's Learn Katakana, and its
companion volume
Let's Learn Hiragana, is a textbook that introduces the learner to the
basics of one of these fundamental Japanese scripts. Being a workbook,
it contains all the exercises that allow the student to master katakana
by the time the book has been finished. Let's Learn Katakana is a
classic in the
field, and the huge number of students that have used it successfully is
a sign of its preeminence as a self-study guide.
