This book is a supplement to the textbook Basic Technical Japanese. It introduces 100 new kanji and more than 700 new words and phrases that appear frequently in documents dealing with solid-state physics. The text offers ten lessons, each presenting key vocabulary and ten new kanji that reappear in the exercises for that lesson and in subsequent lessons, reinforcing learning. The exercises emphasize vocabulary building, kanji recognition, definition matching, and translation skills. An introductory lesson reviews the katakana and hiragana writing systems. The lessons in this book have been keyed to the final ten chapters of Basic Technical Japanese, so that students can use the two volumes together to build a Japanese vocabulary and to practice translation related to solid-state physics and engineering.
