Although the entire book is written in Japanese, it provides an English translation, summarizing the content of the e-mail. On the bottom of each page is a list of vocabulary used for the letter, and additional furigana pronunciations are written above the kanji to provide you with enough clues to help you determine the meaning of the vocabulary. From the get go, you'll learn the proper format of a letter such as the salutation, opening of a declination, declination, ending and signature.
A recommended study item for intermediate and advanced students of the Japanese language.
