Yookoso!, meaning welcome in Japanese, is the second volume of a two-volume series for beginning Japanese courses. Based on modern principles of second-language acquisition, it was the first beginning Japanese text to integrate the teaching of all four language skills (reading, writing, listening, speaking) and to be accompanied by a full complement of ancillary materials. Grammar is treated as a tool for developing the ability to communicate in Japanese, not as the focal point of the text. The illustration program (photographs, line drawings, realia) and the two-color, hard-cover format is unique in this field, providing an attractive context for language learning.
