These cute, little books use manga-style graphics to help English speakers learn the Japanese writing systems. Kana de Manga: A Fun, Easy Way To Learn the ABCs of Japanese! teaches the hiragana and katakana syllabaries, the closest that Japanese has to an alphabet. For each kana are provided the sound, a word using the sound with accompanying illustration and cultural note, the stroke order for drawing the kana, and empty grids for practice. Front and back matter provide kana contractions plus more information about the kana systems. Almost 40 pages are devoted to practice grids, unnecessary for library readers. The volume is inexpensive, cute, and useful, although other kana tutorials that use mnemonics-that is, likening the kana to an image-can be effective, too.
The four Kanji de Manga volumes teach 320 of the more complex Chinese-based kanji characters, of which some 2100 are used in standard Japanese. These books teach kanji only through the kana. This may be a good discipline, but most English-speaking readers would have greatly appreciated Romanizations, too, even if relegated to a back section in place of practice pages. There's no Romanized index or glossary, either. Not a priority purchase.
Japanese Sound FX! is likely to be the most useful of these books, with Romanizations, cultural explanations, and illustrations for many of those untranslated sound effects sprinkled tantalizingly throughout manga. This last is recommended for libraries where manga is popular.
